EV-specific sizes — XL load rated
Reading your size, load ratings, size changes, and pricing
In 225/65R17, 225 is the tread width in millimeters (about 8.9 inches). 65 is the aspect ratio: the sidewall height is 65% of the width, or about 146 mm (5.8 inches). "R" means radial construction, which nearly all passenger and light truck tires use today. 17 is the wheel diameter in inches. Put together, the tire stands about 28.5 inches tall when new.
The code after the size, such as 102H, tells you how much weight each tire can carry and how fast it is rated to go. The number is the load index (102 means 1,874 lbs per tire) and the letter is the speed rating (H means up to 130 mph). Your replacement tires should meet or exceed the load index and speed rating on the placard in your driver’s door jamb.
An XL tire is built to carry more weight than an SL tire of the same size, and it reaches that higher capacity at a higher inflation pressure. Heavier crossovers, trucks, and many electric vehicles come with XL tires from the factory because of their weight. If your vehicle’s placard or original tires call for XL in a size like 225/65R17, replace them with XL. Putting XL tires on a vehicle that only needs SL is fine, though the ride can be slightly firmer.
Often, yes, within limits. A common guideline is to keep the new tire’s overall diameter within about 3% of the original. For 225/65R17, which is about 28.5 inches tall, that means roughly 27.7 to 29.4 inches. A taller tire makes your speedometer read low: with a tire 3% larger, it shows about 58 mph when you’re actually going 60. Also check that the new size fits your wheel width, clears the suspension and fenders at full steering lock, and meets your vehicle’s load rating. When in doubt, ask a tire installer before switching.
Each retailer sets its own prices and runs its own promotions. The total you pay also depends on shipping costs, installation and disposal fees, road hazard coverage, and manufacturer mail-in rebates, which can be worth $50 to $100 or more on a set of four. Stock and pricing can also vary by region. Compare the full cost at checkout, not only the tire price.
The prices we show are the per-tire prices listed by each retailer. Shipping, installation, taxes, and fees depend on the retailer and your location, and are shown at the retailer’s checkout.
Replacing all four keeps handling and braking even. If you replace only two, most tire makers recommend putting the new pair on the rear axle to help prevent oversteer on wet roads. All-wheel-drive vehicles often need all four tires to have closely matched tread depth to protect the drivetrain, so check your owner’s manual before replacing only some.
