4 rugged terrain t/a lt265/75r-16 purchased at odometer 91681. Tires rotated at 100955. Following happened while highway driving. On 8/19/2015, odometer 109831, vehicle vibrating, found bubble (tread separation) on left rear tire. Tire was replaced under warranty. On 8/4/2017, odometer 121840, vehicle vibrating, found bubble (tread separation) on right rear tire. Have not taken tire to dealer yet. Front tires seem to be "singing" with a "rhythm" (best I can explain). I'm having all checked out today. I don't trust these tires anymore.
Body and under body rust and rot to include frame, brake lines and shock mounts. Brake lines failed while I was driving, thankfully at slow speeds and was able to activate the emergency brake.
