What 245/45R20 tires means
The size code is a precise set of measurements. The 245 is the section width in millimeters (about 9.65 inches). The 45 is the aspect ratio, meaning the sidewall height is 45% of that width — roughly 110.2 mm (4.34 inches). The R means radial construction, and 20 is the wheel diameter in inches this tire mounts to.
Add the two sidewalls to the wheel and you get an overall tire diameter of about 28.68 inches, which turns roughly 703 revolutions per mile. Those numbers matter because they set your rolling distance: staying close to your factory diameter keeps your speedometer and odometer accurate. The relatively short 4.34-inch sidewall trades some ride cushion for sharper steering response and a planted look, while the diameter affects clearance inside the wheel well.
Vehicles & uses
The 245/45R20 is a common 20-inch fitment on midsize and larger sedans, sport crossovers, and light SUVs that came with staggered or performance-oriented wheel packages. Because 20-inch wheels are frequent factory and upgrade sizes on these vehicles, this diameter is a popular replacement choice for drivers who want a modern look with usable everyday manners. Always confirm the size against the placard on your driver's door jamb before ordering.

How to choose
Season
Match the tire to your climate. All-season tires balance dry, wet, and light-winter driving for year-round use; summer tires focus on warm-weather grip and handling; and dedicated winter tires are built for cold, snow, and ice. If you face real winters, a separate winter set is worth considering.
Treadwear & UTQG
The UTQG rating lists treadwear, traction, and temperature grades so you can compare expected longevity and grip across models. A higher treadwear number generally suggests a longer-lasting compound.
Load index & speed rating
The load index shows how much weight each tire can carry, and the speed rating indicates its maximum rated speed. Meet or exceed the values specified for your vehicle — don't drop below them.
Warranty
Many touring tires include a mileage warranty, which is a useful signal of the manufacturer's confidence in tread life. Check each model's coverage details before buying.
