IT-level cars coming to a National near you? B Spec Race Cars

[dickita15]

Run them on DOT 180 tires. Anything but 0 dot Hoosiers.

Serious question, are they any series that are actually running with a tire wear limit? I know there are semi pros and for that matter some SCCA classes that run on a spec tire but is there anyone who has made a treadwear limit work?

Lemons [edit] uses a treadwear rating spec on tires. It seems to work for them.

Chumpcar runs @ 190 and up. I was pushing for 180, so that we could use Kumho XS. WE are on the Falken 615 tires. The class gets cheaty as the tires get stickier. That holds for most racing,IMHO. Slower is a lot better racing.
It is a good balance in reality. The lighter cars turn better, and the heavy cars go faster , giving up some turn.
OUR car is an 1800# VW GOLF. It works well.
