Man when I was young and dumb we went looking for tires at U pull it junkyards specifically because they were mostly dry and hard as a rock and would spin forever on my Camaro. I would guess they’d be at least 15 years old back then.
We also put the space saver spare on and tried for the longest skinniest burnout known to man. Probably an 1/8 of a mile. Summer time growing up working on cars with good friends, that I still connect with, making memories. Nothing was better.
not the best idea to run on ancient tires, and looking back it was dangerous, and would never trust crap tires now that I have kids
