BFGoodrich KO2 37x12.50R17 (per tire)
The default tire for a reason: predictable on pavement, tough sidewall, and every shop in the country stocks them. Sizing up from the factory 35 needs a speedometer recalibration, and the tread is not the strongest choice in mud or deep sand.

Runs in the same lane
BFGoodrich KO3 37x12.50R17 (per tire)
The KO2 replacement with a stiffer sidewall and better wet braking, aimed at trucks running higher speeds off-road. It costs more than the KO2, and any size change from stock still calls for a recalibration, not a tune.
Nitto Ridge Grappler 37x12.50R17 (per tire)
A hybrid tread that splits the difference between an all-terrain and a mud-terrain without the mud-terrain highway noise. Wears faster than the KO2 in exchange for more bite in loose dirt, and a size increase needs the speedometer recalibrated.
Toyo Open Country A/T III 37x12.50R18 (per tire)
Quieter on the highway than the KO2 with tread life that holds up over a full season of daily driving. Recalibrate the speedometer after the swap if the new size is larger than stock, since a tune does not touch that number.
