I had my wheels off this afternoon as I was replacing the barrel bolts.

I noticed that on both the front tires I had uneven wear occuring. The tires are newer (1.5yrs) and have been driven about 10000k now of spirited driving. Michelin Pilot Sport 4 S

Car details:
- 06 V8 Vantage
- 20" front and rear
- Kw3 coilovers
- Setup with some negative camber front and rear.

Rear tires have worn quite evenly.

Both front tires have uneven wear on the inner edge near the shoulder. Whats interesting is that there seems to be a distinctive line/flare/edge in the wear pattern - i tried to draw this profile.

Any thoughts on which cause this could be?
- Camber related
- Toe alignment related
- Consequence of spirited driving

Thanks in advance.

Apparently a wheel alignment is in order.

 

Yea - I think the car has probably been setup with some toe in for steering performance. (ive only had it for about 2yrs so not sure how it was last set up)

 

this never happen with the pirelli P zero, it looks like the gum is hard on the outside of your tire.

 

Get it to a certified alignment shop. First thing they will need to do is swap out the fronts to two of the rears. Then they can do a complete alignment job including imspection of all components.

 

Just as a point of reference, I have Michelin Pilot Sport 4s on my 2019 DBS.
Had to replace the rear tires at about 17,000 miles. The fronts have 24,000 miles now...and still counting.
You have a front end issue.
Thanks,
