A question that often comes up is "How much air pressure should I put into my tires?"
This really depends on too many factors to give a specific pressure.
But here is how you can find the correct pressure for your jeep: Take some chalk and draw a line across the tread, from the inside of your tire to the outside. Drive a few blocks. If you wear off the chalk evenly then the tires are at the correct pressure. If you wear the outer edges first then you have too little pressure. If you wear the inner part of your tread off first then you have much pressure.
You could do the same test with masking tape but you would have to drive further to wear it off.
