I have used the Spec Racer Ford tires for atleast 10 years now. Set lap record @ Sebring one time on free tires (2:44+-)Yokes)
I put a proposal up to allow the Goodyear treaded tires for IT cars that can run the 13in. They are not fast, but are very consistant and reasonably durable. Mike ran the school for three days on the Goodyears and than we switched to used Hoosiers. He went 1:29 , Goodyear, 1:27.2 on Hoosier. (ITB Golf)
The cost of the Hoosier is about $200per??
The cost 0f the Goodyear is $0 or 10 $per.
I will bring a car to the Summit point 12 hour , if we can run the cheap/ free tires.
In these days of zero cash racing , and small car counts,reducing the 800$ tire bill seems like a good idea.
PS, we always autocross on these and had zero failures, just lots of miles.
