What 255/50R20 tires means
The size code breaks down into three exact measurements. The first number, 255, is the section width in millimeters (about 10.04 inches) across the widest part of the tire. The 50 is the aspect ratio: the sidewall height equals 50% of the section width, which works out to 127.5 mm (about 5.02 inches). The R means radial construction, and 20 is the wheel diameter in inches this tire is built to mount on.
Add the sidewall on both sides to the wheel and you get an overall tire diameter of roughly 30.04 inches, turning about 671 revolutions per mile. Those numbers matter because they keep your speedometer and odometer accurate, determine whether the tire clears your fenders and suspension, and shape ride quality — a 50-series sidewall gives a firmer, more responsive feel than a taller profile while still absorbing more road than a low-profile size.
Vehicles & uses
This is a size built for many SUVs, crossovers, and some passenger cars. In practice that spans daily highway commuting, family hauling, and light-duty use where a comfortable, quiet ride and good all-weather grip matter most. Because it's a widely fitted 20-inch size, buyers usually shop it for touring, highway-terrain, and all-season purposes rather than dedicated off-road duty. Always confirm the size, load index, and speed rating against the placard on your driver's door jamb before buying.
Brands & options in 255/50R20 tires

Performance & all-weather
For grip across changing conditions, look at the Nexen N Blue 4S 2 and the GT Radial MaxClimate. The Kumho Crugen HP71 is a popular crossover all-season.

Highway and light-truck picks include the GT Radial Adventuro HT and Maxtour LX, the General Grabber H/T (also in a 109H load), the Nexen Roadian GTX, and the value-focused Nexen N'Priz AH5. Budget-oriented brands like Venom Power and Versatyre round out the range. Browse everything on the all tires hub.
How to choose
Season: summer tires maximize dry and wet grip in warm climates; all-season tires balance year-round use; winter tires are purpose-built for snow and cold. Treadwear & UTQG: the UTQG treadwear grade is a relative durability indicator — higher generally suggests longer wear, alongside traction and temperature grades. Load index & speed rating: match or exceed what your vehicle's placard specifies; the trailing letters and numbers (like 105T or 109V) tell you a tire's rated carrying capacity and top sustained speed. Warranty: compare the mileage warranty when weighing long-term value. Confirm each tire's exact ratings on its product page before ordering.
