Tire Brand

I have had two sets of Marathons over the past 14 years. My rigs have been over tired compared to many, 235/80 16E's on 5ers that grossed 10K and 12 K respectively. 80 PSI, I keep them covered when not towing and don't tow over 65 MPH. 9 years on the first US made set and 5 years on the current Chinese made set which I transferred over to my new rig. No failures yet.
