Hello all,


2016 Escalade ESV


I’m upgrading my wheels and tires and before I do so I’m trying to figure out what is causing my tires to wear unevenly in the front. I’ve had an alignment done twice. By two different shops. None of the suspension parts are worn out. New shocks not too long ago. Both times the alignment showed to be in alignment with some slight adjustments made. yet the outside of my front tires are completely worn out in about 25,000 miles. Almost identical wear on both sides. The rear tires are perfectly fine. I realize I should’ve rotated them, but I’d like to get to the issue before I put new tires on it. I’ve read that this can be caused by toe. If it was too much camber, more than half a tire would be worn out. These are both done on Hunter machines by two different shops. Any insights?

Every S10 pickup and Blazer we've had did this. Rotate and air pressure help but they just do it. Do you drive on roads with a lot of curves at speed? Haven't seen this with Tahoes/Yukons though.

If you corner with any gusto at all this is going to happen on a 5000lb+ vehicle in the front. Could it be the alignment? Probably not if it is within specs and you aren't lifted or anything. If you have the front leveled then that can certainly have an effect as it would normally cause the front to go into positive camber some but as you stated you've had it aligned within spec so that should not be the case.

Turning forces. Here in S. Florida, the RH front always looks like that- the constant U-turns on the boulevards do it. That it's equal on both sides, I'm supporting the theory that it's simply cornering loads. You can have the alignment shop add some caster to help with that- I don't know the stock specs, but my experience with lighter vehicles is that about 4* caster works pretty good, on simple suspensions like these. You could go maybe 1/2* negative camber as well. FWIW I always keep my tires at sidewall max, not at the door sticker values- they always wear better and last longer. I don't care about ride comfort, it ain't a Cadillac.

I'm laughing at myself this morning re-reading, because yours *is* a Cadillac.
Next question is how wide are the new shoes you're considering?

My 2015 LTZ on factory 22 wheels shows increased outer edge tire wear. I can hear tires rubbing the fender wells at rear outer edge and see a factory rub strip Also the steering is so smooth and ez I try to be moving as I turn the wheel !!

I'm thinking it's likely the culprit. This Escalade ESV weights over 3 tons. It is a Cadillac, so I do care about ride quality to a degree but I am well aware an Escalade is just a Suburban with more leather on the inside. The magride does a pretty good job, but being on 22's the extra air pressure couldn't make it much worse.

I had 305/45/22 Michelins installed yesterday. $1,600 down the drain. Planning a road trip at thanksgiving, so I wanted new tires on there. Now I am trying to figure out this tire wear issue. I'm thinking it's just a land yacht, and cornering is tough on tires, but may experiment with the toe. image1 - Copy.jpeg

Need to see pics of the alignments you have paid for. Post pics of the before and after printouts. You say is a 2016, 8-9 years old, but no mileage? No worn parts? I very much doubt that. This is all guesswork without seeing the before and after printouts. Plus, inspecting the steering/suspension steps should be discussed. What air pressure is recommended and what air pressure do you have?
