Default 33 inch km2's... what psi should i run?

I want to make my tires last long as possible so I don't want to under/over inflate them and cause them to wear to quickly

It should say on the side of the tire..

And run around 10 when wheeling.

yea but ive heard people running anywhere from 25 up to like 40 so im not really sure what a good psi is, and I always air down to about 10 or 12ish when im wheeling on rocks. about 15 on the beach. but if im just messing around in some local mud holes I don't air down at all

For starters I rotate them every other oil change (every 3,000mi) & I balance mine with 7oz of HD plastic BB's and they r wearing even and iv got bout 20k on them and there at half tread. I run bout 10psi when wheeling and 25-30psi on the road.

the psi listed on the sidewall is the MAX psi that should be ran in that tire, not what SHOULD be ran.

Chalk test is probably the best idea.

The chalk test is the only way to know what the best psi is for you.
