Ok so I'm an idiot and I didn't check the DOT stamp on a pair of tires I recently bought used. Basically they're tires from 2008 so almost no one will mount them for "safety" reasons. Frankly I wouldn't have bought them if I had paid close enough attention to that but here I am stuck with these things. My question is, how risky is it REALLY to mount and run these things? Visually they're not dry rotted at all and tread is like 8/32. I did find 1 place that will mount them if I pay cash lol. I already asked the seller if they'd consider refunding me based on the fact that every other tire shop I called said no way, but the seller is a fucking cuck so he said no. Opinions?
