Tire wear sign of suspension issue?

[Sgtrod]

Greetings,

I had my first track day in my 1LE and noticed wierd tire wear. Can someone help me out? This may be normal, due to driving style or a suspension issue.

Please help me out.

This is the front driver side tire. The passenger side is negligable.

Looks normal for track use. If your going to track a lot then getting an alignment specific to track use would be a good idea.

Thanks. I thought it was weird that one tire only had this wear. The outter tread block has the rear side smooth and the front side like the step on a stair. Thought it was feathering but i have no tire knowledge.

And its on the far outter side.

Maybe from braking hard and turning in hot on right handed turns?

I'm guessing the course is right hand dominate, meaning most turns are rights. Tire looks really good though. there is a thread about reading tire wear in the road course/auto cross section.

That and Tire Pressures! You can use White Shoe Polish on the Tread & Sidewall to see how much the Tire is rolling over. Then adjust your Tire Pressures accordingly.

That little triangle to the left indicates where you want the wear to reach on track days.
You could let out a little air pressure.
You were close.

Could be what some have already discussed or it could be the alignment is in need of adjustment.

When was the last alignment?
Can you post the specs?

Your description here says "heel-toe wear", which has nothing to do with downshifting while braking. It's front to back unevenness of individual tread block wear that typically happens when either braking or acceleration loads are high and not distributed over more than one or two of the tire's tread ribs. It's reasonable to get this when driving very aggressively, but it raises a few questions when only one tire on an axle is so affected.

I'm going to agree with the guess that the track is right-turn intensive, and I'm going to add that you may be doing a significant amount of braking with the wheels steered somewhat right but not when they're steered left.

You may also have a bit of cross-camber, where the LF does not have as much static negative camber (what the alignment machine measures) as the RF.

And you might want to check the rear suspension for thrust angle (probably a net effect aiming the rear wheels slightly to the right).
