30ish. It will depend a lot on the weight of the vehicle. Start at 30, run a chalk test and adjust from there. There are dozens of threads about pressures and how to do the chalk test. Search the site a bit.

Thanks, did some more reading and people seem to be running them between 35-40 psi. Thanks again.
