Best Tires for Ford F-350 Super Duty Dually: Fitment Guide

The best tires for a Ford F-350 Super Duty dually must match the exact truck before their tread design becomes the deciding factor. This guide compares seven identifiable LT245/75R17 light-truck offers, including highway and all-terrain designs. That shared size is a conditional comparison group, not a recommendation for every F-350 model year, trim or wheel package. Read the truck’s tire information label and owner documentation, then confirm the full specification, wheel suitability and dual-rear-wheel requirements. A matching seventeen-inch rim diameter or heavy-duty label is not enough. The goal is to separate the products by their documented purpose while showing where exact variation, dual-load data and purchase conditions still need checking. No towing-capacity increase or vehicle-specific comparative performance result is claimed.

Quick Picks

All seven original designs remain relevant for comparison in the selected LT245/75R17 versions. Michelin’s configuration-specific selector supplies a fitment lead for a 2025 F-350 XL 4×2 DRW; it does not establish universal fitment or turn every tire below into Ford original equipment. Some retail titles abbreviate the service description, so the delivered sidewall and current supplier specification must establish the complete dual rating. Passenger or non-LT versions with similar size numbers are separate products. No tire was removed merely because a newer model exists, and no package quantity was counted as another design.

1. Michelin Defender LTX M/S2

The selected Michelin Defender LTX M/S2 is the LT245/75R17 load-range-E version with a 121/118S service description. Michelin identifies the corresponding LT size as MSPN 38846 and presents the family for on-road use. That makes it a highway-oriented candidate to compare when the truck’s approved specification matches. It is not interchangeable with Michelin’s non-LT 245/75R17 XL version simply because the first size numbers look alike. Confirm the LT designation and complete service description on the actual offer and delivered tire.

Michelin’s selector lists this LT version for a specific 2025 F-350 XL 4×2 dual-rear-wheel configuration. Treat that as a bounded fitment lead, not evidence that all F-350 years, trims, axle setups and modified wheels use it. The paired load indices distinguish single and dual service, which matters at the rear of this truck. Have the correct load and inflation requirements checked for the actual vehicle rather than multiplying a headline tire capacity into a new truck or trailer rating. Tire selection does not increase the manufacturer’s vehicle limits.

The practical reason to compare this design is a predominantly paved-road use pattern. The manufacturer’s comfort and tread-life positioning does not establish a noise measurement, stopping distance or service life on your truck. Review current warranty eligibility for the exact purchase and commercial use, rather than treating a family claim as guaranteed mileage. Plan the quantity and matching condition needed for a six-tire vehicle with a qualified tire shop. A newly purchased single tire should not automatically be paired with a substantially worn rear companion because both carry the same model name.

My Recommendation

Shortlist this LT version for a placard-compatible F-350 dually used mainly on paved roads. Confirm MSPN, full service description and dual-wheel suitability before ordering. Choose another properly matched design if your routes require a different tread emphasis; neither Michelin branding nor a selector example establishes universal truck fitment.

2. Michelin LTX A/T2

Michelin LTX A/T2 is the all-terrain alternative in this comparison, selected in LT245/75R17 E with a 121/118R description. Michelin publishes this size in more than one sidewall or original-equipment-coded version, including MSPN 06682 and 21691 entries. The selected Amazon title does not settle every one of those details. Confirm the exact manufacturer number and sidewall presentation before ordering, particularly when matching existing tires. A recognizable model and size establish the candidate, but they do not identify every selectable version.

The maker positions LTX A/T2 for paved and unpaved use, including gravel-road endurance. That is a stated design purpose rather than a measured advantage over the other six offers on an F-350. Do not convert it into a puncture-proof claim, an unrestricted off-road recommendation or a promise of better wet braking. A mud-and-snow description also should not automatically become a three-peak-mountain-snowflake claim. Check the exact delivered tire markings and current requirements for the conditions and jurisdictions where the truck will operate.

This design is worth comparing when maintained gravel and work-site access are a meaningful part of the route, provided the exact vehicle specification permits it. Keep the dual pairing, wheel dimensions and load requirements in the purchase plan. A tire’s intended terrain does not resolve rear clearance or matching diameter. Review the current warranty and original-equipment conditions for the actual version instead of assuming a headline family mileage statement applies to every purchase. The verified offer is one tire, so arrange the correct installation quantity rather than treating a single listing as a complete dually replacement set.

My Recommendation

Consider LTX A/T2 when the approved LT specification matches and gravel access is part of the truck’s normal work. Confirm the exact same-size version and matching requirements before purchase. Choose a highway-oriented alternative if your priority is predominantly paved use, without assuming either category wins every comfort or traction comparison.

3. Firestone Transforce AT2

Firestone Transforce AT2 is the commercial all-terrain candidate selected in LT245/75R17 E. The authenticated offer identifies article 000184 but abbreviates the service description to 121R. Firestone’s size catalog confirms the model in the selected LT size, and manufacturer product material distributed through the VA also identifies that article. Before buying for dual service, have the complete sidewall rating and current supplier data confirmed; the abbreviated single-load title alone is not the full rear-axle suitability check for a dually.

The intended distinction is commercial on-road and off-road use, rather than a claim that AT2 adds towing capacity or outperforms every highway tire. Firestone’s catalog does not list a limited-mileage warranty for this entry, so do not transfer a Destination-family mileage figure or another Transforce model’s conditions. A comparative maker claim against the original Transforce AT also is not proof of an advantage over all competitors. Evaluate the actual route and exact specification instead of treating a rugged tread photograph as a complete performance assessment.

The selected tire can remain a candidate when its complete load, wheel and dual-use specifications match the truck. Confirm article number, quantity and delivered markings with the installer before the tires are mounted. Check whether any current coverage terms differ for commercial service, and do not infer severe-snow certification from an all-season or all-terrain label. On a working dually, matching rear companions and maintaining correct cold pressure remain separate tasks from choosing the tread. If the seller cannot provide the missing dual information, choose a fully documented offer rather than assuming the first load index answers both service positions.

My Recommendation

Compare Transforce AT2 for a commercial all-terrain use case only after the complete dual rating and exact article are confirmed. Its named identity supports research, while the short retail title leaves an important check unfinished. Choose a documented alternative if the actual supply cannot establish the required specification before installation.

4. Bridgestone Dueler H/T 685

The selected Bridgestone Dueler H/T 685 title identifies LT245/75R17 E and abbreviates the service description to 121R. It is a different candidate from the non-LT 245/75R17 112T version that appears in other catalogs. Do not transfer that passenger-version load description, inflation information or warranty row to this LT offer. Manufacturer product material identifies an LT245/75R17 article 001341, but the selected retail title does not itself verify that full article identity. Confirm the exact supplied version and complete dual-load data before purchase.

Bridgestone discusses heavy-duty construction, wet-weather design and a footprint intended to promote even wear for the H/T 685 family. These are design statements, not measurements proving a particular result on your truck. Do not turn them into a higher allowable trailer load, freedom from hydroplaning or guaranteed tread life. The highway-oriented role is useful for organizing the comparison, but actual suitability still depends on the approved tire specification, load, wheels and installation. A brand page’s broad wording cannot replace those vehicle checks.

For mainly paved work routes, compare this exact LT version with the Defender and HT3 candidates after resolving the version details. Ask the supplier for the full service description and current technical data needed by the installer. Keep sidewall appearance and article identity consistent when matching existing tires, rather than selecting by a similar photograph. Review actual warranty terms for the supplied tire and intended service without borrowing conditions from a non-LT row. Arrange a complete replacement and matching plan appropriate to the six-wheel truck; a listing for one tire does not establish the correct purchase quantity or companion condition.

My Recommendation

Shortlist the LT H/T 685 for predominantly paved service if the supplier confirms its full dual specification and the installer verifies the truck match. Distinguish it from non-LT 112T versions. Choose a fully traceable alternative when article identity or dual-use data remains unresolved, rather than relying on a family name.

5. Atturo Trail Blade A/T

Atturo Trail Blade A/T has a documented LT245/75R17 version identified by the maker as item 16017, also shown as TBAT-I0048347. Its 121/118S description matches the selected offer. The manufacturer publishes separate single and dual load data and an approved rim-width range for this exact row. Those details provide a useful basis for the installer’s check, but they are not an automatic fitment approval for every F-350. Compare the complete row with the actual truck and wheels before ordering this selected variation.

The maker presents Trail Blade A/T as an all-terrain design and identifies the family with the three-peak-mountain-snowflake marking. That does not establish ice-braking performance, unlimited winter traction or a reason to disregard local winter requirements. Inspect the exact delivered tire markings and current specification. The retail material also discusses UTQG grades for passenger sizes; those figures should not be copied onto this LT version. Likewise, a ten-ply rating is a service-capability designation, not permission to state that every tire contains ten physical carcass plies.

This is an all-terrain comparison option for an approved LT configuration, not a verified cheapest choice or a measured winner for noise or wear. The published maximum pressure is not a universal cold operating pressure for the truck. Use the vehicle requirements and an appropriate load assessment with the installer. Confirm the full set and rear-companion matching plan, and review warranty conditions for the actual purchase rather than treating the mileage headline as guaranteed service life. If the wheels or spacing have been modified, resolve their suitability separately; the published tire width alone does not establish safe dual clearance.

My Recommendation

Consider this exact item when an all-terrain design suits the route and its documented LT and dual specifications match the truck. Check delivered markings and current warranty conditions. Choose another correctly matched design if your priorities differ; 3PMSF and a load-range letter do not settle ice performance or complete vehicle compatibility.

6. Cooper Discoverer HT3

Cooper Discoverer HT3 is the highway-focused pickup and commercial-van design in the selected LT245/75R17 121/118S E offer. Its authenticated identity remains relevant, and a manufacturer data-book search result also identifies the corresponding size and service description. The full data-book file could not be fetched during this review, so uninspected table details are not presented as independently checked specifications. Confirm current manufacturer and supplier technical information for the actual purchase instead of relying on a model name, old brochure or broad fits-trucks statement.

The product positioning emphasizes highway work, grooves and tread features intended to support wet traction and wear behavior. Those statements describe its design purpose rather than proving a stopping-distance, noise or mileage result on an F-350 dually. Do not broaden all-season wording into a confirmed severe-snow or ice-performance claim. Similarly, a satisfaction-program reference in retail features does not establish current eligibility for this seller, tire age or commercial use. Read the applicable terms before treating any trial or coverage program as part of the purchase decision.

HT3 can remain on the shortlist for predominantly paved routes when the truck’s full approved specification matches. Compare its actual supplied markings, wheel requirements and dual application with the installer, especially when replacing only part of the vehicle’s tires. The listing is a single tire, not a complete six-tire package. Obtain a matching plan appropriate to existing tread condition, size and construction instead of assuming a new tire is compatible with any old HT3 companion. If current technical or warranty information is unavailable, resolve that gap before ordering rather than substituting specifications from another Cooper highway product.

My Recommendation

Compare HT3 for highway-oriented use on a truck whose approved LT requirements match the selected version. Confirm current technical data, tire identity and supplier terms before purchase. Choose another documented option if those details cannot be established; the model’s commercial positioning does not independently prove fitment or a particular service life.

7. Hankook Dynapro XT RC10

Hankook Dynapro XT RC10 is the more rugged-terrain candidate, selected in LT245/75R17 E with a 121/118R description. The current US maker page identifies material code 2021368 and lists the dual index separately. That is a useful traceable specification rather than a generic aggressive-tire claim. Confirm the supplied code and complete markings against the actual truck requirements. Do not substitute a Dynapro AT2, AT2 Xtreme or another similarly named Hankook model because it shares the brand or a familiar tread appearance.

Hankook describes block and shoulder features intended for off-road traction and includes noise-management design elements. Neither establishes a measured comfort benefit, reduced road noise or improved traction on this truck against the other candidates. The exact size row also identifies the three-peak-mountain-snowflake marking. Treat that as a specific marking to confirm on delivery, not proof of ice performance or permission to ignore winter conditions. Choose the terrain emphasis for the route you actually drive rather than assuming the most aggressive appearance is the strongest choice for every loaded vehicle.

The published size row includes approved rim information, but that alone does not resolve an F-350’s dual spacing, wheel modifications or vehicle load limits. Have those conditions checked before installation. Current web specifications and an older catalog can differ in secondary measurements, so use current manufacturer data for the exact supplied tire rather than mixing rows into an invented specification. Maintain the correct matching condition and cold pressure for both rear companions. If the truck mainly covers paved routes, compare the highway candidates before accepting a rugged-terrain design whose additional emphasis may not serve the normal job.

My Recommendation

Shortlist RC10 when rugged-terrain use is a real requirement and material code 2021368 meets the truck’s approved LT and dual-wheel needs. Verify current data and delivered markings. Prefer a correctly matched highway option for a predominantly paved route if the rugged design adds emphasis you do not need.

How to Choose Tires for a Ford F-350 Dually

Identify the truck and its approved specification before comparing tread patterns. Model year, trim, axle configuration and wheel package can change the answer. Treat the selected LT245/75R17 offers as a comparison group only when your actual tire label and documentation permit it.

Match the complete specification and dual application

Check the LT designation, complete size, load range, single and dual indices and speed symbol. A non-LT version with similar numbers is not an interchangeable alternative. Read the tire information label and the correct model-year owner manual, and have the installer resolve wheel width, dual spacing and any modifications. A selector result for one 2025 XL 4×2 DRW configuration does not cover every F-350. Maximum tire capacity does not increase axle, wheel, vehicle or towing ratings. If a retail title abbreviates the dual information, obtain the complete specification before purchase rather than inferring it from the single index.

Choose the tread for the actual route

Compare highway-oriented models for predominantly paved service and all-terrain or rugged designs when unpaved access is a recurring need. These categories describe intended use, not an independent ranking of wet braking, noise or wear on this truck. Confirm exact winter markings; an all-season or M+S label does not automatically establish 3PMSF, and 3PMSF does not establish ice performance. Review the current warranty for the supplied version and intended commercial use. A mileage headline or satisfaction statement is conditional coverage, not a promise that every tire will deliver that service life.

Plan matching, pressure and the installation quantity

A dually has six road tires, but each verified offer must still be checked for its actual quantity. Have a tire professional assess existing wear and rear-companion matching when replacing fewer than six; shared model lettering alone is insufficient. Use the vehicle’s specified cold pressures and appropriate load guidance, not a sidewall maximum as a universal setting. Confirm access to inner valves and inspect both rear companions rather than relying on the visible outer tire. Our tire-pressure gauge comparison explains gauge choices, although an ordinary gauge still needs the range and valve access suitable for this truck. Follow the correct owner manual’s rotation and pressure instructions for the actual wheel configuration instead of transferring another year’s diagram. Verify the delivered tire identities before mounting and address any unresolved mismatch first.

Frequently Asked Questions

Is LT245/75R17 correct for every F-350 dually?

No. It is a selected comparison size. Read the actual truck label and correct owner documentation; year, trim, wheels and modifications can change the required specification.

Why do dual load ratings matter?

The paired rear installation uses the specified dual-service rating and appropriate inflation requirements. A single-load figure or multiplication of maximum capacities does not establish the truck’s permitted axle or towing load.

Can a non-LT 245/75R17 replace the selected LT version?

Do not assume so. Similar size numbers can hide different load capabilities and construction. Match the vehicle’s full approved specification and obtain professional confirmation before substituting anything.

Does 3PMSF guarantee good ice braking?

No. Confirm the exact delivered tire marking and suitability for the conditions. A severe-snow marking is not a universal winter-performance guarantee or a substitute for applicable local requirements.

Do I need to buy six tires from one single-tire listing?

First confirm the replacement plan and actual listing quantity with the installer. A dually has six road tires, but partial replacement requires a proper assessment of matching condition, specifications and rear companions.

Final Verdict

Match the actual truck first, then choose a documented tread design for the route. Defender LTX M/S2, H/T 685 and HT3 provide highway-oriented comparisons; LTX A/T2, Transforce AT2, Trail Blade A/T and RC10 provide different unpaved-use emphases. None is universally compatible with every F-350 dually. Resolve full dual specifications, exact versions and matching requirements before ordering, and do not treat tire ratings as an increase in vehicle capacity.
