Fast tire wear on passenger front
Hi. I have a question I cannot find anything on here about. I put a 2 inch spacer lift on my 99 about a year ago, new shocks and new tires. The passenger side front tire is wearing alot faster than the driver side. Pressure is good, alignment good, things seem tight. Out of ideas.....I put a new adustable track bar on also. Tire seems to be wearing more toward center, but as I said, pressure is right. 31x10.50x15. Any ideas?

On stock steel wheels. The pressure was around 40 on both, i lowered to 35 some time ago. The driver side is at same pressure....not as much wear. Cooper discoverer at3.

The wide tires on 7" stock wheels with too much pressure is causing some of your problems for sure. Stock PSI is only 32 IIRC. Bigger tires need less pressure. My 35s on 15x8s only run about 26 PSI. Weird that you've got less wear on the driver's side though. I would take the jeep back to wherever you got the tires from, they might be able to exchange your passenger side tire.

Yeah, that's it. 40 lbs is too much. If you ran that for a year it explains the wear. 30 would probably be your spot with the 31's. Just drop the pressure and rotate them.

You are correct.
Yet, you cannot get folks to understand this.
I run 31s on a 8" wheel and 285/60/18 on a 9" wheel.........both at 45lbs.
Those who run low pressure to compensate for the wrong wheel width get poor performance.

Besides the wrong wheel width........your alignment is not correct.

NO! NOT WRONG!!!!!!!!!
He's only wearing one side......his alignment is out!
If it was ONLY the crowning due to wheel width (which takes place over time, shorten life of the tire.......truly shows itself after about 30K miles) then ALL of his tires would be showing equal wear.

Here's what a long time tire expert and friend told me.
Begin with stock pressure recommended by the manufacturer for the stock tires.
Adjust up or down as needed.
Chalk test is best as it eliminates any guesswork/variances in tire types and so on.
You wouldn't catch me running any where near 40 PSI on any of my Jeeps, much less 45 PSI.

Couldn't agree more with ya. To many myths on the interweb. I just got 235/85/16s on my jeep. Im running 25 in the rear and 27 upfront. And based off of dirt and chalk, the wear is even. And im pretty sure running 3-3.5" wider tire than rim is perfectly fine especially if you offroad.
