I have 3 or 4 15" tires that can be used for rollers. They are various sizes but all have tread and hold air so they can be used for rollers. They are street tires, not aggressive at all. Come get em before they go to the dump.

ttt. I actually have 5 of various sizes. All are car sizes but heck for rollers, who cares.

to the top one last time.....probably heading to the dump this weekend.
