i have 4 toyo t1-s's i'm considering selling
all have pretty good tread. very minor dry rot around the outside edge, just a little cracking. 2 tires have 2/32nd's tread remaining and 2 have a little more than that, probably 3+. tires are good on wet/dry, they handle and hook pretty well, better than the brand new coopers i have on my other wheels.

looking for about $120 obo for them
