Re: high-tec-retread tires ?
Iíve been running a set for about 18 months. They compound is soft, tires flex good across tread. Most of the time I do not air down below 12-15 psi. Wear hasnít been too noticeable, but I don't drive mine on the street too often anymore.
The sidewalls are the weak point. I have several concerning cuts in my sidewalls, and have complete cut one on the trial (4-inch cut). They grip good on the rocks due to the soft compound and flexy carcass. That is also the weak point. The soft compound would likely wear quick if driven on road daily, more so on a heavy rig, and the soft flexy carcass = weak sidewalls. You have to remember the sidewalls may already have 40k miles on them.
I got them delivered to my door for $60 each for the 31x10.50 OTR mud. They suck in the mud, around here we have soil types that dictate swampers or boggers. Very few other tires work well. With the Suzuki I lack the power to spin the tires hard enough for them to clean adequately.
I bought them because I needed 4 tires and thatís all I could afford at the time. They have served me well, and will probably serve most well. The next set Iím getting will probably be Swamper LTBís. They are much softer and flex better than the SXís, comparatively same cost as any decent mud tire, and they work well in the slick stuff like the SX.
