What PSI?

[TylerJY]

What PSI should I run 33x10.5 KM2's at for normal street/highway driving??

You can decide this yourself by airing the tires up too much, then pulling into a level, flat, smooth concrete garage, and airing the tires down until you get an even full tread contact pattern with the concrete floor. Write your numbers front and rear in the door jamb with a Sharpie.

 

My guess is it won't be anything near the recommended pressure listed on the sidewall of the tires. I'd bet it'll be something like 20 to 25 psi front, 17 to 22 rear. Air up the rears when you throw a load in the bed.

tires don't have a "recommended" pressure on them. they list a MAX pressure. :thumbsup:

take some chualk and draw a line on the tire straight across. then drive forward and back a few times then look and see what rubbed off the line. air down or up until the line goes away evenly.

 

 

i havent tried that but its seems like it would work. :dunno:
