got some 13 inch slicks need to go to a good home Pair of 21.5X11X13 goodyear radials Formula Mazda mid compound, and a pair of 21.5X8X13 same. these are WAY to hard a compound for my DSR, aged, but 40 -50% left 7.50 each (cost to have them dismounted) or all 4 for 20 bucks. these would probably work pretty good on a heavier car.
3 Mcreary Formula for slicks VERY aged, but have tread depth still on them, better than nothing FREE just come get them 21X8.5X13
