I have a Xpress 1756 aluminum boat, and I have a tire question. The trailer/boat/motor and everything included are about 1800#. I am running Titan ST radial tires in 165/80/13. I had a tread seperation on the way to the lake yesterday. I was wondering what could have been the problem. I had SEVERAL thousand miles on the tires and this is the first problem I have ever had. I am running 45# of tire pressure.<br /><br />Also we dropped the tire when we were changing it and dented in the edge of the rim......can this be fixed?????<br /><br />thanks for any ideas<br />longshot
