So, I got new tires this spring (Toyo T1 sport), and have done only 9 autocross events on them. They still have plenty of tread, except for the front edge (I've attached a view of the front, and the rear for reference). Will I chord these tires with another event or two?

I want to stay in the SCCA road tire stock class, so camber plates are not an option. So what do I do to manage my tire wear, and not waste these tires?

-Move these tires to another set of wheels for street use only, and dedicate my stock wheels on a fresh set of better tires for autocross ONLY

-Used tires?

-Accept this sort of wear, and buy new front tires every spring

-Just move on to non-stock class: STX

To be honest that doesn't look that bad, even after you saying they have taken 9 autox's. It is normal to have worn the front shoulders as autox's are really tough on guiding the tires. The road band looks just fine with pleanty of thread. I don't think a bit more camber will make much of a difference tbh, as your are driving hard on them. I'd get a square setup and rotate. You could balance wear that way much better.

How do you rate the T1 sports btw, I'd like a set of them.

From my limited experience, i can really only compare the T1's to the OEM pZero RFT's. For autocross in the dry, the T1's really seem to perform about the same as the pzeros, maybe worse. With the T1's, I've actually been placing worse until the last few events. They feel sloppier, but with a similar ultimate grip. They also make a lot of noise (which i like).

Now in the wet, the T1's seems to perform better than the pzero's. In one event I placed 3 of 26 in the first 2 runs on a wet course, as the course dried, I went to 8th in my last two runs ( i usually place right in the middle)

On the street, they seem like decent tires for the price. Performance in the rain is better than the pzeros.

That doesn't look too bad.
This is what mine looked like after one event. I have now ordered more appropriate wheels and tyres.

You can't tell much about tread depth from the shoulders but those still look to have some tread left. You could run those for awhile yet.

well, the tread depth is good, I'm just wondering how much more autocross the shoulders can take. I'm wearing the shoulders at a much greater rate, will more autocross eventually chord an otherwise good tire?
