About 265/50R20

Factory fitments for 265/50R20 include the Dodge Durango, Jeep Grand Cherokee — meaning replacement tires in this size see steady demand and broad brand availability. At 30.43″ overall diameter, 265/50R20 turns 663 revolutions per mile, which is the reference point the factory speedometer and odometer were calibrated against. The 50% aspect ratio gives it a moderate sidewall suited to sporty street driving and responsive turn-in. The 20″ rim pairing is typical for luxury SUV and performance-oriented platforms, so compatible wheels are easy to source new or used.
