What size (in inches) is a p235/75 r15? If this is already a 30 inch tire then that is what I will have to go with I Think. I am guessing that 31 x 10.5 r15lts? wouldnt fit then. would something like a 30 x 9.5 r15lt? Basically I am looking for the biggest tire I can put on a stock 93 Navajo/Sport. I just hate the fact that there appears to be a lot of room in the well for more tire!

According to the metric tire chart @http://www.4lo.com a 235/75/15 is 28.9". Some folks have been able to stuff 31's under and others only 30's. When you decide to buy the tires, go to a place that will let you test fit both to see which on you can fit under without problems. If a little triming is needed, just remember,..'the sawsall is my friend'. Good luck.
