Tireman9, the couple across from us came home from the Good Sam rally with a new Landmark. Credit goes out to Heartland, it was delivered with GY G614's. Carriage is gone now, however they were pushing out similar 5ers on Duro ST tires. Keystone one of the largest manufactures seems bent on staying the coarse on Marathon ST tires. Most of these trailers come with GAWRings that are right at the tire ratings, and most of these trailers are bought to "see America"! So here we are with thread after thread about tire problems.
The premise that oversizing an ST tire regarding weight capacity is an universal answer does not completely resolve the problems. One is still traveling on a light weight tire that is to easily damage by road hazards.
There is a reason commercial grade tires are more or less over built in comparison to other tires. We have identified these entries numerous times, so I will not repeat them again. They do come in 16" E's and G's and 17.5" H's and J's. I wise consumer will seek them out and pay the extra to be on the best. The not so wise will continue to post about their failed tires! Or in some cases clam up and not omit that they should have bought better tires. Chris
