What tire pressure are you KO2 guys running, highway

Wondering if there is any agreement on best pressure for 265/70R17 BFG KO2's. Highway driving. Between these tires and the FrontRunner roof rack, my MPG is down to less than 15.

 

39psi

 

sounds right.. I believe I was at tire specs?… 40psi?… on vacation so I can’t confirm, but I do get between 14-17mpg depends on route.

 

I’ve got 285 70 17 KO2s C load, with a canopy, lift, winch and I’m getting 17mpg comb and around 20mpg on highway road trips with 60mph speed limits. I run 35 front 32 rear. Course I’m 2nd Gen not 3rd Gen - different engine and tranny
That roof rack won’t help that’s for sure

 

265/70/16 LT

front. 37 psi. cold
rear. 35 psi

 

This is a good place to start. It will show you the appropriate pressure based on the OEM tire size/ load range/ pressure and whatever aftermarket tire size /load range you installed.

Roof racks kill gas mileage, also.
