About the 225/70R15 size
The late second-generation F-body and C3 Corvette size. The factory designation was GR70-15 in the mid-1970s and by 1980 the window sticker simply said P225/70R15, so this one is a genuine factory radial rather than a bias conversion; it is also the accepted substitute for F70-15. Raised-white-letter versions from Cooper and BFGoodrich are what most Trans Am and Corvette owners fit, narrow whitewalls come from the Hankook Optimo H724 and Coker, and bias-ply FR70-15 reproductions are available for judged cars. Ratings are S and T, the same ballpark as the original B and S. Diameter is 27.4 in, so it fills a 1979 Trans Am wheel opening correctly where a 60-series does not.
What the numbers on the sidewall mean
A 225/70R15 tire is 225 millimeters wide, its sidewall is 70 percent of that (about 6.2 inches tall), and it mounts on a 15-inch wheel. That works out to an overall diameter of roughly 27.4 inches. Every replacement has to match all three numbers, and the load index and speed rating on the placard inside the driver's door have to be met or exceeded.
In this size our picks are marked 100T on the Kumho Solus TA11 and Cooper Cobra Radial G/T (1,764 lb per tire, rated to 118 mph) and 100S on the BFGoodrich Radial T/A (1,764 lb per tire, rated to 112 mph). The first number is the load index, the letter the speed rating; a tire with equal or higher values than your placard is fine, a lower one is not.
Our guide on reading a tire size walks through the markings, and this one lists every load index and speed code.
Our three picks, side by side
One tire at each price level from what the retailer stocks in this size, with the mileage warranty and UTQG grades as published by the manufacturers and their retailers. Treadwear is the number to compare: it is a relative wear rate, so 700 should last roughly twice as long as 350 on the same car.

Frequently asked questions
How much do 225/70R15 tires cost?
Expect $82–$101 per tire for a budget brand, $101–$127 for a mid-range tire like the Cooper Cobra Radial G/T, and $127–$190 for a premium tire like the BFGoodrich Radial T/A. A set of four therefore starts at about $328. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 225/70R15 tires?
225/70R15 is original equipment on Pontiac Firebird Trans Am (1975-1981), Pontiac Firebird Formula (1977-1981), Chevrolet Camaro Z28 (1977-1981), Chevrolet Corvette C3 (1973-1982) and Chevrolet Caprice (1980-1990, 9C1 police), among others. Always confirm with the sticker inside your driver's door, because trim levels and wheel packages can change the size.
What is the best 225/70R15 tire?
For most drivers our mid-range pick, the Cooper Cobra Radial G/T, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the BFGoodrich Radial T/A is worth the extra. On a tight budget the Kumho Solus TA11 is a sound choice.
Can I replace just one or two 225/70R15 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
