All of the blown tires were installed new at the end of January 2014. They had less than 1500 miles on them.
Anyway thank you to all that gave me information to help me out. I decided to go with new rims and tires. 16 inch LT Tires. I just finished driving over 300 miles on them and what a difference in the feel of the 5er. Very smooth and solid. I am very happy so far but will keep you posted.
We are full timers and needed to get the tire issues behind us.
Thanks again for the input.
