About the 215/45R18 size
Almost a Mazda3-only size, V or W rated. Limited fitment list but solid selection of touring and UHP all-seasons; a popular winter size on the OE wheels.
What the numbers on the sidewall mean
A 215/45R18 tire is 215 millimeters wide, its sidewall is 45 percent of that (about 3.8 inches tall), and it mounts on a 18-inch wheel. That works out to an overall diameter of roughly 25.6 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 93W on the Pirelli P Zero All Season Plus (1,433 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 compact car in this size
Compact cars are nearly all front-wheel drive, and that is what the traction laws look at. In Colorado the Passenger Vehicle Traction Law applies on the 126 miles of I-70 between Dotsero and Morrison from September 1 to May 31: a two-wheel-drive car must be on 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. Most all-season tires in this size are M+S rated, so the marking is usually there; the tread depth is what catches older tires. A light car on narrow tires actually does well in snow because the tire cuts down to the road instead of floating on it, so a dedicated winter set in this same size, swapped on in November, is the simplest upgrade if you live where it snows.
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.

Other years and wheel packages of the same models came on 195/65R15, 205/55R16 or 205/50R17 instead, so read the placard inside the driver's door before you order.

Frequently asked questions
How much do 215/45R18 tires cost?
Expect $65–$94 per tire for a budget brand, $94–$168 for a mid-range tire like the Continental ExtremeContact DWS06 Plus, and $168–$257 for a premium tire like the Pirelli P Zero All Season Plus. A set of four therefore starts at about $260. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 215/45R18 tires?
215/45R18 is original equipment on Mazda3 (2014-2018, s Touring/Grand Touring), Mazda3 (2019-2024, Preferred/Premium) and Mazda3 hatchback (2019-2024), 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 215/45R18 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 Pirelli P Zero All Season Plus is worth the extra. On a tight budget the Kumho Ecsta PA51 is a sound choice.
Can I replace just one or two 215/45R18 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.
