Tire pressure for Iroks

[mississippizj]

Putting em on my Grand Cherokee. They are 36x13.5x15. What is the normal tire pressure for the best ride and wear. It doesnt see a huge amount of street use, but will be driven on the street daily for short distances.

i'm running the 36" Iroks bias on my cj. for around town stuff (street) i actually only run about 17psi cold to get a nice flat contact patch across the tire. if you air them up to much, they ballon pretty good and you're only running on the middle tread.

off road i run em at about 5psi

A Grand Cherokee isn't light. I would run them at max (30). If they seem to wear too much in the middle, let out some air. I've got some 36 bias Wranglers on my Blazer and I run them at about 35. They have seemed to wear about right.
