LT275/60R20

LT275/60R20 is the light-truck version of this size, with the same nominal height and width: 33.0 by 10.8 inches. LT tires have stiffer construction for heavier loads and towing, run at higher pressures and carry a load range (C, D, E or F) instead of a passenger load rating. Fit LT tires where the door placard calls for them or the truck works hard; on a light-duty vehicle they ride firmer than the P-metric size.
