What 255/70R17 tires means
The size code describes the physical dimensions of the tire. Here is exactly what each number means for 255/70R17:
- 255 — the section width across the tread is 255 mm (about 10.04 inches).
- 70 — the aspect ratio: the sidewall height is 70% of the section width, which works out to 178.5 mm (roughly 7.03 inches).
- R17 — radial construction on a 17-inch wheel.
Add it up and the overall diameter is about 31.06 inches, and the tire turns roughly 649 revolutions per mile. Those figures matter to you in practical ways: overall diameter and revolutions per mile drive speedometer and odometer accuracy, so staying close to your original size keeps your gauges honest. The tall 7-inch sidewall cushions impacts for a more compliant ride and helps protect wheels off pavement, while the ~10-inch width sets your footprint and clearance in wheel wells.
Vehicles & uses
This is a truck and SUV size. The wide footprint and tall sidewall suit vehicles that value a smoother ride and enhanced responsiveness, which is why the highway, all-terrain and mud-terrain patterns offered in this size are geared toward light trucks and sport-utility vehicles. Always confirm the size against your door-jamb placard or owner's manual before buying, since the correct fitment varies by vehicle.

How to choose
Season: All-season tires balance year-round grip and are the most common choice here; dedicated summer tires maximize warm-weather traction; winter tires are engineered for snow, ice and cold. Match the type to your climate and driving.
Treadwear & UTQG: The UTQG rating printed on a tire's sidewall grades treadwear, traction and temperature, and a higher treadwear number generally suggests a longer-lasting tread compound. Check each product's listed rating before you decide.
Load index & speed rating: The two characters after the size (for example, the 112T seen on many options here) tell you the load capacity and maximum speed rating. Choose ratings that meet or exceed what your vehicle's placard specifies—never below.
Warranty: Mileage and road-hazard coverage differ by model, so compare the terms on each tire you're considering.
