Check the size printed on your current sidewall and match it exactly to 245/50 R20, then verify against your door-jamb placard or handbook. The 245 width, 50 profile and 20-inch rim diameter must all match, and you should also follow the specified load index and speed rating for the vehicle.
Buy 245/50 R20 with a load index and speed rating that meet or exceed the figures shown on the vehicle placard. This size is often used on heavier vehicles, so many options are offered with higher load ratings or XL construction, but you should not guess - select the exact rating your car requires.
For 245/50 R20, summer tyres suit warmer conditions and prioritise dry and wet grip, winter tyres improve traction and braking in colder weather, and all-season tyres are a practical year-round choice if you want one set. If you drive in hilly areas or regularly see frost and snow, a winter or all-season 245/50 R20 option is usually the safer fit.
Only choose XL 245/50 R20 tyres if your vehicle placard specifies an XL or reinforced fitment, or if the required load index is only available in XL. XL construction helps the tyre carry higher loads at the correct pressures, which is common for SUVs and vehicles that tow, but it should match the manufacturer specification.
It is best to fit the same 245/50 R20 tyres across each axle for consistent grip and handling, especially on SUVs with higher centre of gravity. If you cannot replace all four, replace tyres in pairs and keep the same type on the axle, avoiding mixing run-flat and non run-flat 245/50 R20 unless your vehicle is approved for it.
