Hello all, I was wandering how many people out there are running steel belted radials versus polyester tires on their trailers. My trailer (Big Tex 6'x16' open top) came with 2-ply polyester tires all the way around. A friend told me that it would be better (and cheaper) to run used steel belted radial tires on the trailer instead of polyester. Another friend told me not to get rid of the polyester tires as they tend to last longer, can handle more weight, and are skinnier than steel belted radials (easier to back up with skinny tires as compared to wider tires). I visited www.tirerack.com this evening and found no polyester tires. So my question is, is it better to run steel belted radials or polyester tires on your trailer? With either opinion, I would like to know why you do or why you don't prefer one tire over the other. I am trying to make an informed decision based on facts and not what somebody heard on the street. Thanks.
