I have for sale, three good used Nitto Nt01's tires. Tires have three track days (12 sessions) on them. Looks like 5/32 of tread left. I have a forth tire, but it does have a cut in it. No cord showing though and I did use it for the three track days (12 sessions). Like to sell the three good ones for $150 each. If you buy all three I will give you the fourth tire for free. Would like to sell local WNY area as shipping has got to be costly!
