Before I start getting blasted about Death Wobble threads let me explain:


So I noticed that my front right tire is significantly more wore down then any of my other tires, and I was wondering if anyone had any idea what might cause this, I have stayed on top of my tire pressure they are all at 29 PSI. and have been for as long as I have had the tires on. Why would just the front right wear down? And what relations would this have with the severe death wobble I have been experiencing.


As Always Thank You.

Worn, unbalanced tires can certainly contribute to DW.

Three questions:
1 - How many miles on the tires?
2 - Have they been rotated regularly?
3 - Has the alignment (toe-in) been checked?

The answer is yes,they have been rotated regularly and have had a toe-in done, I kinda figured that it could contribute to the death wobble I am just more curious as to how one tires wears unlike all the rest. And they have about 9K on them.

I have this same problem. I have more air pressure, but the middle of my tire is worn more then the rest of it (them). ODD.....

Nothing odd about it.

My RFF outside edge wears faster too, on three different vehicles (Jeep, Expy, and Van). What they have in common is 4wd.

My opinions (on road):
Left turns are usually faster then rights at city intersections
Normal drift is to right on a crowned road, so normal steering input is a little left
My driveway is a left turn from street
Going to work requires a left turn, at about 15mph from flat to an off camber 8% grade
U turns (when picking up kids at school) are left turns
All 3 vehicles are relatively high COG

For the van, it is fairly well known to adjust the camber on RF to compensate. RF camber should be max or just a little over max, while LF is mid to low spec.

---
Could be ackerman, camber, toe, or a combination. Most likely thought is just steering geometry compromises with 4wd/truck needs.

With the Jeep, I could play with static toe to compromise with scrubbing, but I worry more about toe being set to prevent DW.

how much is bad, I am only running 35-40lbs. I know if you have too much you wear the center/ too little wear edges.... but only the right front is wearing that way....

BTW, its a 35/12.5/15

All of my vehicles wear heavy on the front right tire. I always contributed it to hard left turns and U-turns, Most parking lot driving involves lots of hard left turns.

I could understand what everyone is saying, I understand some more wear is to be expected on the front right tire, but this wearing issue has just started to occur since my last rotation about 000 miles ago, before that they were all wearing at the same rate, so what could cause it in 3K miles. But thanks for everyones input I do appreciate it.

Interesting. I just brought my TJ in yesterday for a severe wobble that started a month ago. It got progressively worse over the past week. Symptoms were that between 48-52 mph the steering wheel shook like crazy. 20k miles on it. Wobble seemed to be from drivers front and the wheel and tire "looked" fine.

Ended up being that the tire was out of balance. The weight had fallen off.

There's far far better techs on this board than I am. Hopefully one will chime in. But I wonder if something may have been damaged. After my lift, I ran my old stock tires for a bit, and didn't have the alignment set properly (It was toe'd out a bit from my futzing with it) Both tires were worn on the inside. Since it's just one side, it sounds weird.

Do you have an adjustable front trac bar? Is the front axle centered? Lifting pulls the front axle toward the driver side. I'm not sure what that would do to tire wear if it was off.

Have someone turn the wheel back and forth - locked to locked and watch everything move under the front, see if anything looks wrong. Check the torque on your control arms (and everything else for that matter), and look for any possible damage. Do you have adjustable control arms? adjusting them affects camber and it may be off, causing it to ride on the inside of the tire.

Jack it up and grab that tire and see if it moves. I think if it moves left/right like it was turning the Jeep, it's tie rod related, and if it moves top/bottom it's a wheel bearing. I may be misremembering that, but it shouldn't move in either of these ways.
