There is no single tire size for every 2011 Hyundai Sonata. Tire fitment differs by trim and wheel package. This roundup compares five all-season listings in two sizes—215/55R17 and 225/45R18—only for vehicles whose door placard specifies the corresponding size and rating. The base GLS uses a different 16-inch size in tire catalogs, so this page does not cover that fitment. Check the placard and manual before buying.
The ratings shown below come from the listings. CarInsightPro has not road-tested these tires. Many marketplace offers are for one tire; one product below is listed as a set of four. Confirm quantity, selected variation, warranty, and return terms.

|---|---|---|---|
| Starfire Solarus AS 215/55R17 94V | 215/55R17 94V | Single tire listing | The listing describes an all-season touring tire and states a 50,000-mile warranty and M+S marking. Check the current written warranty and maintenance conditions. |

| Fullway HP108 225/45R18 95W XL | 225/45R18 95W XL | Set of four listed | The product title identifies four all-season high-performance tires in 225/45R18 95W XL. The listing reports no tread-life estimate; confirm that the selected package is still a four-tire set. |
| Uniroyal Tiger Paw Touring A/S 225/45R18 XL 95V | 225/45R18 XL 95V | One tire listed | The product page identifies an all-season tire in 225/45R18 XL 95V. It gives limited feature details; check the current manufacturer specifications and warranty before purchase. |
The two sizes are different fitments, not alternatives to mix on the car. The placard’s load and speed ratings control; confirm them even when a tire uses the same size code.

How to choose for a 2011 Sonata
- Identify the trim: cataloged sizes vary, including 16-, 17-, and 18-inch combinations. This list does not cover every trim.
- Match the full code: compare size, load index, and speed rating on the tire with the door label. Do not use a listing that has a lower rating unless Hyundai confirms it for your VIN.
- Check package count: one tire and a set of four are different offers; confirm the selected quantity before checkout.
- Read warranty requirements: mileage warranties can require regular rotation, alignment, and proof of maintenance. The written terms control.
- Ask an installer: have the tire shop confirm the correct size and rating, inspect the wheels, and mount/balance the tires to Hyundai specifications.
How the two listed sizes differ
The 215/55R17 and 225/45R18 sizes use different wheel diameters and sidewall proportions. They are separate factory fitments, not interchangeable tire choices for one wheel. A 17-inch tire cannot be mounted on an 18-inch wheel, and a size change can affect clearance, handling, speedometer readings, and wheel compatibility. Use the size on the car’s placard unless Hyundai has approved another complete wheel-and-tire setup for that exact trim.
Both selected size groups include V-rated examples, but the load index and construction still need to meet the placard. XL construction and a higher load index do not make a different size automatically suitable. Check the tire pressure recommendation for your vehicle; do not copy pressure from a product page or another trim.
Warranty mileage can help compare listings, but it is conditional. Rotation, alignment, pressure, road surface, temperature, and driving style affect wear. Keep purchase and maintenance records and read the written warranty before using its mileage figure to compare cost.
Frequently asked questions
Do all 2011 Sonata trims use these two sizes?
No. Catalogs list different sizes by trim and wheel package, including a 16-inch configuration not covered here. Read the placard on your vehicle.
Can I use 225/45R18 tires on a car with 215/55R17?
Do not treat them as interchangeable. Use only a size approved for the exact Sonata and wheel setup.
Why were 91-load-index 18-inch listings left out?
The tire references available for the 225/45R18 Sonata fitment show a higher load specification. A listing that does not meet the required rating should not be presented as a match; verify the placard and Hyundai guidance.
Are these choices ranked by testing?
No. This is a comparison of listed sizes, ratings, and package details, not an independent road test.
Does the listed price include four tires?
Usually not. The Fullway product here is listed as a four-tire set; the other selected pages identify a single tire. Check the current variation and cart quantity.
Conclusion
Choose by the Sonata’s exact placard size and rating, then compare products that meet that specification. This shortlist covers 215/55R17 and 225/45R18 options; if the placard says 205/65R16 or another size, use a listing for that exact fitment instead.
