My 5th wheel had Goodyear ST tires put on at the factory. Build date was August 1998 and I replaced those tires in June of 2010 to make a trip out west with three other rigs. I thot it a shame to trash good tires but my wife and another RV.net person very strongly felt it should be done. Never had a flat except the spare tire got to the point it wouldn't hold air so I left it at home. Sold the trailer in Jan of 2016 and the replacement Goodyear ST tires looked nearly new. I had TPMS in the tires and kept the cold pressures within 5lbs at all times. The new 5th has the Chinese tires on from the factory, build date is Feb 2015, bought new Feb 2016 and I've put 2000 miles on it. I installed TPMS and intend to operate it with cold pressures within 5 psi also so time will tell.... Ask me in ten more years...
I would expect new tech Carlisle tires to do at least as well.
The old Goodyears were awesome tires... too bad the new ones are terrible :( No way the new Marathons are going to last more than five years i bet. Mine lasted three months before i had one rip apart. My old overloaded equipment trailer i had in the 90's had Marathons on it and i never once had a flat or any problems with them.
