About the 235/50R18 size
Mustang base size, W or V rated. Mix of UHP all-season demand from Mustang owners and touring demand from Impala owners.
What the numbers on the sidewall mean
A 235/50R18 tire is 235 millimeters wide, its sidewall is 50 percent of that (about 4.6 inches tall), and it mounts on a 18-inch wheel. That works out to an overall diameter of roughly 27.3 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 97W on the Goodyear Eagle Sport All-Season (1,609 lb per tire, rated to 168 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.

Winter on a sedan in this size
Most sedans in this size are front-wheel drive, and that decides what the snow laws ask of the tires. On the 126 miles of I-70 between Dotsero and Morrison, Colorado's Passenger Vehicle Traction Law runs from September 1 to May 31: a two-wheel-drive car needs tires marked M+S, 3PMSF or rated all-weather by the manufacturer, with at least 3/16 inch of tread, and fines start at $130. The touring all-seasons that dominate this size are almost all M+S rated. An all-wheel-drive sedan passes on the vehicle alone, but all-wheel drive only helps you accelerate; braking and cornering on snow come entirely from the tire, so an all-weather tire with the 3PMSF symbol is the better year-round answer in the snow belt.
None of our picks in this size, the Kumho Ecsta PA51 and Continental ExtremeContact DWS06 Plus, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions
How much do 235/50R18 tires cost?
Expect $82–$124 per tire for a budget brand, $124–$192 for a mid-range tire like the Continental ExtremeContact DWS06 Plus, and $192–$266 for a premium tire like the Goodyear Eagle Sport All-Season. A set of four therefore starts at about $328. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 235/50R18 tires?
235/50R18 is original equipment on Ford Mustang (2015-2023, EcoBoost/GT base), Ford Mustang (2010-2014, GT), Chevrolet Impala (2014-2020, LT), Audi Q3 (2015-2018) and Mercedes-Benz GLA (2015-2020, GLA250), 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 235/50R18 tire?
For most drivers our mid-range pick, the Continental ExtremeContact DWS06 Plus, 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 Goodyear Eagle Sport All-Season is worth the extra. On a tight budget the Kumho Ecsta PA51 is a sound choice.
Can I replace just one or two 235/50R18 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.
