Tire wear question?

[europeanspec]

I am running Toyo R888's and have found what is to me an unusual wear pattern. The 888's as you know have chevron like grooves. I have on the front tires a pattern where the inside groove edges are sharp and very worn. The outside grooves however are not as worn and the edges are kinda rolled with excess rubber built up along the entire groove. The outside edge of the tire also has turned slightly blue. Is this a camber issue?? I have adjusted the camber down slightly as suggested by Toyo and the Miata crew who use these tires. I also adjusted the tire pressure down significantly and the temps were even across the tire after the last race.

The blue may be from rubbing, as well.

The "Bluing" on the edges is very common for me running hoosiers. I have had old tires turn blue and even tires with one weekend on them turn blue... could certainly be sun damage, but i have not noticed a substantial drop in performance caused by the bluing specifically.

"Blueing" is overheating--not rubbing or UV exposure.

Burnt tire rubber "blues".

Can be camber, over aggressive driving, etc.

Camber I understand, as a fairly new driver you are gonna have to explain"over aggressive driving". I have been on the track and have been "nudged" by aggressive driving which I have been under the impression is required to excel at this sport.

By aggressive he means over driving the tires, which leads to over heating, which leads to the tires falling off. Usually the heavier cars need to "manage" their tires through out a race.

For example, if the car understeers and you keep driving the car harder and harder into the corner resulting in you having to turn the wheel more to get bite. This will over heat your front tires.

Hope it makes sense......

On a side note, If you're getting "nudged" by the faster cars maybe you're not getting out of the way fast enough!! he he he.............

I do try my best not to be a rolling roadblock but both the car and driver are improving with every race so the desire to move over is not as strong as it once was!!!!

BTW the last race was a milestone for me at NHMS. I was not passed or lapped and finished on the lead lap!!!!!! No nudging there!!
