I have an extreme trailer with 235/60/15 tires which I'm hearing are low profile and tough to find for a trailer. Anyone run into this problem with an extreme trailer or have any ideas? I'd rather not have to cut and raise the fenders just to fit a trailer tire.... I've also been told that the company (Carlisle) isn't even making the tire any longer. Forgot to mention that the existing fenders are set up for this size tire and don't have room to go to a different tire size????
