I had some older tires on, I believe they were one step down but since I had duallies I figured they would last. I had just ordered new tires, driving down the road and BANG
blew the tread out the bottom of the tire, not the side but the tread blew. Well, I "was" on my way to a job.
If I didn't have duallies, I would have needed a tow.
For the price difference, its worth having
