That is the max pressure under full load. Run about 28 to 30 and go from there. There is always the good old chalk test. Make a chalk mark across the tire, drive fwd and then see if the entire tread width is making contact with the road surface...adjust accordingly. At 50 psi your JK probably drives terribly!

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
