Tire Sidewall problems of the 2003 Jeep Grand Cherokee

Driving a Jeep 2003 mich lx tire 235/65/r17 sidewall dry rot, reported to mich they said it was the ozone, as a scientist and an ndt level 4 inspector I was surprised that the person they sent me to address the issue spent less than 10 minutes looking at the remaining 3 tires. The person refused to give me any written report the tires only have 15k on them. Michelin will not give me a voucher for 4 free tires I am afraid others will have the same issue the dry rot side wall will blow out and cause a death or several. Michelin recalled 1,3 million tires voluntarily but refuses to recall mine. Beware of michelin tires.

2003 Jeep Grand Cherokee. The consumer stated driver's side rear tire sidewall disintegrated. There is only 31,000 miles on the vehicle. The rest of the tires were weather rotted. These tires have never been repaired. They were the original tires on the vehicle. Goodyear, p255/75r16. The tire was taken to the dealership. Instead, it should have been taken to goodyear. There was no wreck when this happened. The tires were properly maintained. It is a leased vehicle.
