Do the Toyo's need to be shaved to be a decent competitive tire or can the tread stay. Do the Toyo's need to be heat cycled prior to using in a race. Thanks for the advice !!!!!

Re: tred or no tred. Is your hope to use them as rain & dry tires?
Toyos don't need to be heat cycled.

I have 1 set already setup with full tread for rain. I now need a good set for dry racing as the current set is less than optimal!!!!!!!

Dan--My experience with Toyos is that they can be a "greasy" tire when hot, so for the dry, they should be shaved.
Adds to the expense, unfortunately.
Thank you, I will have them shaved, greasy is not good!!

When I was starting out, I ran full tread RA1's in the dry. I did not think they were greasy, but they did not have competitive grip levels. As I wore down the tread, the grip got better and better. I would say you would need to shave an RA1 down to 2/32" (normal shaving is 4/32") to be competitive. I would say I gained about 2 sec (on a 1:30 lap time) on a nearly used up tire versus when I ran that same tire full tread. I never heat cycled my RA1's.

Dan, I'd shave them to 4/32". Maybe if it were a spec tire for the class I'd do 2/32" but part of your decision obviously financially driven and it really won't make that much difference. Besides, after a couple of races you'll have the tires down to 2/32" anyway.
You know, I still feel bad about not having been able to help you more when at the Glen. I will never eat at that restaurant again!

If anybody at Road Atlanta is looking to get rid of 14x6s real cheep or free, let me know. I will be lurking around the pits both days and am interested in any brand, any condition.
Dave is right, most of the grip is gained as the initial tread depth is lost. To give more info, I would say i gained ~1.5 sec from 8/32" (full tread RA1) to 4/32", while only gaining another ~.5 sec from 4/32" down to corded.
I would always specify depth (or at least ask what depth the retailer usually does), just so there are no mistakes.
