Do you guys think that the tires go boom if you are running close to MAX weight? There are factors built into everything. My DRV is 21k rated and for over 4 years full timing it hasn't broke nor the 21k pin box. It actually weighs 23k, I also have 17,500# on the axles.
With the GY "H" tire all you need to do is inflate per load and keep an eye on the center three ribs. If they appear to be higher than the outside ribs then you have GY replace the tire. That is the only thing that can happen with these tires other than road hazard.
This is what to look for, the only ones that seem to have this issue is some that came on 2016 DRV's.
