I have been in the trucking business for many yrs. I have a tire man , independant that I have used for a long tome. He has gotten old like me but before he quit working on big truck tires he workjed on a lot of dump trucks here in Houstpn. I saw him with a tire spread apart on the bench one day witha bout a 3 inch wide strip cut out of the side. I asjed him what gives and he told me he was sectioning it. A sidewall repair that I had never seen before but he did them on dump trucks quite often because they cut them on construction sites so often. I did not get to stick around and watch him finish but evidently it was a common thing to him. It was a really neat looking cut and a real good looking job of work he was doing and he told me later that it was for the dump trucks as they did not make enough money to buy tires when they cut one on the sidewal every time. If you need a tractor tire fixed that way, find you a lomg time old repair guy who has heard of that before. He might not but maybe he knows someone who does do t. Devious
