i have a 95 4runner 3l 6cylinder 4wd. I'm running 31x10.5 15' kumho ht's mostly on the highway with a little light off road/ what tire pressure should i be running. 42 on the front and 48 on the rear and it searches around on the road. I also tow a moderately heavy 17ft center console boat. I do have heavy duty shocks on the rear.

 

i think we had a post on tire pressure recently, dont kno if they covered trailers tho

 

34-35 psi hot would be best
