how many reports of blowouts on Towables have we seen on the forums or experience ourselves and..Marathon tires was featured a lot more than once.
As in our Holiday Rambler they used older light truck tires not up to the weight of a loaded or even empty unit. Plus...tire squirm when jacking them around to park or even on really curvy roads, with two axles or more. We lost two and the other two were getting ready to shed their threads and the Fifth Wheel wasn't even
two years old. They put what ever tires and wheel they can get at the best price, read cheapest to get them out the door, on most of the units.
I changed our tires from a G to an H rating LT truck tire and a better grade of tire also and next larger size and from 16 to 17 inch and to aluminum rims from steel. Those Marathon and other ST tires are only rated to 65 mph? I do not wish to drive a rolling obstacle down the road. After so many reports over the years I believe ST tires should be relabeled to RTB ready to blow or shed threads. Apparently their essential criteria is how cheap can we make them to attract RV mfgs. Marathon tires should read out of breath and will self destruct before the marathon is over, IMO.
