About the 245/40R18 size
Classic sport-sedan size, W/Y summer and V/W all-season. Michelin Pilot Sport 4S and Continental DWS06 Plus are the volume sellers.
The numbers mean: 245 mm section width, sidewall height 40 % of that width, and a 18-inch rim. Overall diameter works out to about 25.7 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.

Expect $84–$108 per tire for a budget brand, $108–$205 for a mid-range tire like the BFGoodrich Advantage Control, and $205–$323 for a premium tire like the Continental ContiProContact. A set of four therefore starts at about $336. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 245/40R18 tires?
245/40R18 is original equipment on Subaru WRX STI (2015-2021), Subaru WRX (2022-2024, Limited/GT), Audi A4 (2009-2016, Prestige), Audi A4 (2017-2024, Premium Plus), Audi A5 (2018-2024), Hyundai Sonata (2015-2019, Sport 2.0T), Mercedes-Benz C-Class (2015-2021, AMG Line rear), Chevrolet Corvette C7 (2014-2019, base front) and Chevrolet Corvette C6 (2005-2013, base front), 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 245/40R18 tire?
For most drivers our mid-range pick, the BFGoodrich Advantage Control, 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 Continental ContiProContact is worth the extra. On a tight budget the Kumho Ecsta PA51 is a sound choice.
Can I replace just one or two 245/40R18 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.
