I am thinking about scaling back to a single axle trailer since gas is predicted to take another big hike and also because the dual axle trailers seem to burn through tires quicker. I am wondering if people can give me some input into how many miles they are getting on their tires for single and double axle trailers? I go through 2 sets a year it seems like. So I would save 50% by having only 2 tires to replace each time plus single axle trailers should last longer with tires since there is no drag on the rear tires when you turn. Any thoughts?
