These are the factory tires from RAM. I have had 2 tires fail within 13,000 miles. Both tires have large cracks on the outside shoulder. Eventually both tires went flat. I ran the tires at the factory recommended 70PSI for the front of my truck.
It looks to me that the tires are just not up to handling a heavy diesel truck. I drive very conservatively. Yet the inside tread pattern looks like it has been abused off-road for many miles.
I have zero confidence in these tires and will be replacing with Michelin tires.
