I have a set of 285/60R20 Discoverer AT3 XLT tires that I purchased new for my -??14 Ram 2500 in December of 2020. On June 7th of this year (2023) I had my tire -??cave in-?? in the middle due to the belts in the tire separating. This defect on the tire caused an extreme wobble and made the vehicle unsafe to drive. The tires in question had 33k miles on them and my local dealer said they would not be warrantied and I was forced to pay $900 to replace both front tires. On August 19, the same defect occurred on one of the 2 remaining tires (tires have 37k miles on them). This defect in the belts/cords again cause the tire to -??cave in-?? and have a death wobble while driving down the road. I own numerous vehicles and have been through several sets of tires on each of them and have never experienced 1) an extreme failure of the tire like this and 2) this high of a failure rate (currently at 50%). These tires are unsafe for the road and need to be recalled!

Driving down the I-10 East of junction I felt a slight vibration and attempted to pull over and as I was doing so the passenger rear tire blew out and bent in the fender bed of my truck and broke the stabilizer bar for the bed skin. The tread separated from the side wall. There was no tread left on the tire, only sidewalls. I removed the tire and put on the spare to get home. Went to discount tire the next day and found out there was a recall on the same tire but different size. They replaced the tire with a new one and filed a claim with kumho and sent the defected tire to them.

Tire sensor system goes off all the time and then resets after awhile. No certain speed or time.

TPMS does not allow setting tire pressures to the recommended tire setting from the tire manufacturer without triggering warning light and nag screen on startup. Constant warning light and nag screen correction will lead to driver complacency, negating the purpose of TPMS alerting the driver to a potential problem with the tires. TPMS required over inflation results in potential loss of vehicle control due to loss of traction. Abnormal tire wear due to tire over inflation increases risk of hydroplaning and loss of control of vehicle. Ram customer service has been contacted and confirmed that this problem is systemic, by design, and can not be corrected at present time. Potential fix is to reprogram BCM, allowing dealers to reset TPMS to appropriate setting for tires and actual load with appropriate documentation.

The tire pressure sensor will not go off and keeps blinking "low tire pressure. I have made seven attempts to get this resolved. I was told by the dealer I bought the truck from last night that there is no more he can do. They over inflated the tires to 80 psi to make the sensor go off but the tires are only rated for 65psi max. This over inflation had voided the tire warranty from the tire manufacturer. This could also result in a tire blow out and accident which could cause death to me, my family or passengers. I need to know how to get this problem resolved before anyone gets hut or killed.
