The stock tire for my truck is 255 70 18
My upgraded tire is 285 55 20
Comparing the height of each, the 285 55 20 tire raises my truck only 1/8" which is most likely the closest match they found. If Toyota installed 285 50 20 tires, the truck would be lowered and it they installed 285 60 20 tires the truck would be raised. Larry G.
