I was up in Madras, Oregon watching the solar eclipse on Monday. On the way back the traffic was extremely bad, so I took Google's suggestion and went on the detour. I eventually ended up on a forest road. The LR4 handled it with no problem at all, but afterwards I noticed my driver's front tire (BFG T/A KO2) has a small cut on the sidewall. After the trip I took it to America's Tire to let them check it out. They said the cut only went through the first of the 3 plys, it didn't expose the core and not sign of ballooning. So it is still same and didn't recommend placement. The tires only has 1500 miles on it. I have the certificate (warranty) on the tire, so if I replace it, will cost me $40 to purchase a new certificate.
Do you think the tire is still safe to use? For $40, should I replace it?
