Time to put some tires on my 91 - it's had 205 passenger tires since I bought it used (with the 4" lift!). But taxes are back and it's time. I wanted LT235/75R15's for the stiffer sidewall, thinking they would be tougher for the rocky terrain I get into. The tire stores are all quite surprised that I don't use a P- rated tire, like their books list it for the Cherokee. What do you think? Am I going overboard? Russ

 

You get just a bit more tread depth with LT tires, so that translates into longer tread life. You will lose some softness in the ride, but not enough to care about.

 

Actually the LT tire has a higher weight rating then a P tire. Tread depth/tread life have nothing to do with P vs LT.

 

Mine are LT245... bought it that way with stock suspension.

 

Yes, I know that. I was just stating that the LT has a bit more tread depth, I was not getting into the load rating because it does not matter on an XJ.

 

You guys are making me feel better about my choice! It' sure hard finding a tire guy who knows enough to talk from his head rather than what his book or computer says!! Russ

 

i got some wrangler duratrac's. they are 10 ply, unfortunatly, i forget what rating, but they are pretty rugged, have a good sidewall, and chew thru snow!!!! jeezus do they love snow! i havent gotten stuck with them so far. my most recent success story: end of the day, sun setting, pull in to office to grab paperwork, female coworker w/ stuck (kinda high centered...) suby forester. she says "yea, that durango that just left tried w/o ANY success..." i say "we have a jeep: your not stuck." so i throw the chain on her tow point, tie it onto my axle (really starting to think that tow hooks might be nice ) i get the chain taught and literally, literally, my tires didnt even spin a bit and we judt walked it right out. the durango musta had **** tires, or not in 4 cause there were spin marks all over the place. so yea, thats my vote.

 

Just remember that an LT truck tire usually runs at a higher tire pressure than a standard P-metric, so you'll want to make sure to keep the pressure somewhere around 50 psi to eliminate unwanted squirm and unusual wear patterns. The door jam sticker information goes out the window as soon as you change from the recommended stock tires.

 

LT rated tire will be fine. Just don't get anything more than C rated tires or you're wasting money. The Cherokee doesn't need the 8 or 10 ply, D or E rated tires because it is a light weight rig and you will not be hauling thousands of pounds of stuff. The C rated tire will usually cost 30-40 dollars less per tire compared to a D or E rated tire.
As for using a chain for vehicle recovery, don't you could get someone hurt.

 

35psi will work fine for an XJ with LTs on it.

 

I have 235 duratracs. I was wondering what psi should i run for dd only for now. I am more interested in tire life and mpg than comfort.

 

A Chalk test would help get you started.

Rotate them often and check the air pressure every fill up. That should get you the best mileage and tire life.

 

I just ordered these today, be here in a couple hrs

In the LT265-75-16 flavor

 

sorry to the op. i don't mean to jack your thread. but please one last ?

i do check them every 2 weeks. i run 37lbs. is that enough?
thanks.

 

Can't say over the net, but that is probably suffecient. To find out what you need to run take a crayon and mark all the tires and drive a couple blocks in a straight line, if it wears the center, but not the edges back down a few psi, if it wears just the edges and not the center add a few lbs, until it wear evenly.
