BFGoodrich All Terrain T/A KO3 37x13.50R22/F 128R

Load Range F is the headline on this one. The 37X13.50R22LT BFGoodrich All-Terrain T/A KO3 carries a 128R service description at Load Range F, which puts it in heavy-duty three-quarter-ton and one-ton territory rather than on a half-ton weekend truck.

What that buys you is carcass stiffness under load - useful if the truck spends time with a gooseneck behind it or a slide-in camper on the bed. What it costs you is a firmer ride when the bed is empty, and more air pressure needed to carry rated load. Read the load table, not the door placard, if you have gone up in size from stock.

The KO3 is BFGoodrich's current-generation all-terrain, so the pattern is tuned for year-round road use rather than pure trail work. Available to order at Rev Auto Club.
