About the 245/40R20 size
W/Y rated 20 in sport size; Camaro SS front (rear is 275/35R20). Summer UHP for the Camaro, grand-touring all-seasons for Impala owners.
The numbers mean: 245 mm section width, sidewall height 40 % of that width, and a 20-inch rim. Overall diameter works out to about 27.7 inches. Any replacement has to match all three, and the load index and speed rating on your door sticker must be met or exceeded. Our guide on reading a tire size walks through it.

What vehicles use 245/40R20 tires?
245/40R20 is original equipment on Chevrolet Camaro SS (2016-2024, 20 in front), Chevrolet Impala (2014-2020, LTZ/Premier), Cadillac CT6 (2016-2020, 20 in), Polestar 2 (2021-2024, 20 in), 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 245/40R20 tire?
For most drivers our mid-range pick, the Firestone Firehawk Indy 500, 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 Michelin Pilot Sport 4S is worth the extra. On a tight budget the Kumho Ecsta PA51 is a sound choice.
Can I replace just one or two 245/40R20 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.
