What 255/45R20 tires means
The size code breaks down into exact measurements that describe the tire's shape:
- 255 — the section width across the tread is 255 mm, or about 10.04 inches.
- 45 — the aspect ratio: the sidewall height is 45% of the section width, working out to roughly 114.8 mm (4.52 inches) tall.
- R20 — radial construction on a 20-inch wheel.
Add the sidewall on both sides to the rim and you get an overall diameter of about 29.04 inches, which turns roughly 695 revolutions per mile. Those numbers matter for real reasons: overall diameter keeps your speedometer and odometer reading accurately, sidewall height influences ride comfort and how the tire absorbs bumps, and section width affects clearance inside the wheel well. Staying on the factory size keeps everything reading true.
Vehicles & uses
The 255/45R20 belongs to the popular 20-inch fitment class you'll find on larger sedans, sport crossovers, and SUVs. Offerings in this size range from all-season ultra-high-performance passenger-car tires to touring and street/sport SUV tires, reflecting the mix of comfort, grip, and mileage buyers in this class typically want. Because it's a widely fitted size, both grand-touring comfort tires and sportier performance options are readily available. Always confirm the load and speed ratings called for on your door-jamb placard before buying.

How to choose
Season: Summer tires deliver maximum dry and warm-weather grip; all-season tires balance year-round usability; winter tires are built for cold, snow, and ice. Match the type to your climate.
Treadwear & UTQG: The Uniform Tire Quality Grading rating (treadwear, traction, and temperature) helps compare expected wear and grip between models. A higher treadwear number generally suggests a longer-wearing tread compound.
Load index & speed rating: The number and letter after the size (for example 101V or 105H) indicate how much weight each tire can carry and its rated maximum speed. Meet or exceed the values on your vehicle's placard.
Warranty: Many touring and all-season tires include a mileage treadwear warranty, so factor that into value when comparing.
