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.
The numbers mean: 215 mm section width, sidewall height 45 % of that width, and a 18-inch rim. Overall diameter works out to about 25.6 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 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 Michelin Pilot Sport All Season 4 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.
