Firestone dirt track tires

Old Firestone 7.50 / 14.00 - 16. Grooved Rear R154. Dirt track tires. One had the inside tread shaved ( look close on pic) probably at a track but appears to not have been mounted or used but ******s still on. Other looks like it hit the track for a few races. Both are checked/ cracked but should hold air with tubes. I run similar set equally cracked and they are fine.
Prefer local pickup otherwise shipping costs are on you. Price reduced to $400.
