What 255/65R18 tires means
The code on the sidewall breaks down cleanly. The 255 is the section width in millimeters (about 10.04 inches across the widest part of the tire). The 65 is the aspect ratio, meaning the sidewall height equals 65% of that width — roughly 165.8 mm, or about 6.53 inches. The R means radial construction, and 18 is the rim diameter in inches it mounts to.
Doing the math, the overall tire diameter works out to about 31.05 inches, and it turns roughly 650 revolutions per mile. Those numbers matter to you: overall diameter drives speedometer and odometer accuracy, so staying in this size keeps your readings honest. The generous sidewall height helps absorb bumps for a smoother ride, and knowing the width helps you confirm clearance in the wheel well.
Vehicles & uses
This is a light-truck and SUV size. As retailers describe it, 255/65R18 tires help an SUV or light truck stay steady, quiet, and confident across daily miles, and the size commonly appears on many crossovers and midsize SUVs. Because fitment varies by model and trim, always confirm the size printed on your door placard or current sidewall before ordering rather than assuming it fits a given vehicle.

How to choose
Season
Match the tire to your climate. Summer tires prioritize warm-weather grip, all-season tires balance year-round performance for most drivers, all-weather models add stronger cold and light-snow ability, and dedicated winter tires deliver the most traction in ice and deep snow.
Treadwear & UTQG
The UTQG rating on the sidewall covers treadwear, traction, and temperature grades. A higher treadwear number generally suggests longer expected tread life, but compare it alongside the manufacturer's mileage warranty rather than in isolation.
Load index & speed rating
Check that the load index and speed rating meet or exceed what your vehicle's placard specifies. Many 255/65R18 tires carry a 111 load index, though some are rated 109 or higher, so verify the exact code before buying.
