GY ENDURANCE, Stellar record. NUFF SAID.

As mentioned be sure your suspension is dialed in.

How do you know your trailer weighs roughly 12,000 fully loaded? Have you taken it to a CAT scale or some other scale to have a good idea of the weight? How do you know you aren't way over weight?

Put on LT tires not ST, I have a 14K 5W and travel about 7o most of the time, zero issues. I have run LT tires on all my 5W's and do not have tire issues, just watch pressure. There have been good reports on some newer ST tires, Sailun and Goodyear 614s

check the tread wear. is it flat, on the edges or only on one side. also I was plagued with blowouts until I went to rims rated for more than 65 psi, as having e rated tires at 90 psi was causing the rims to crack and leak. thus blowing a tire due to under inflation and heat. I would have the wheel bearings cleaned and repacked with high temp grease. new seals. every 2nd year. if any signs of wear shows, then replace the bearing and race. + seal. balance the tires. new valves wu=ith tires. I like metal stems... make sure the tire sidewall doesn't have a warning for speed. most trailer tires are only rated for 60-65 mph. (they used to be rated at 55 mph). using LT tires is a upgrade. just make sure they are rated for more weight than you are hauling. with a good safety margin..

I would clean, and inspect the hubs, and do new Timken races, bearings, and seals if the hubs look ok.

Your first blowouts are not unexpected as the tires were old when you purchased the rig. GY Marathons have fallen out of favor over the years, and I don't think the GY Endurance makes your size. Sailun, although Chinese-made, has a stellar reputation. In fact, I've only heard of one failure, in multiple forums, and the reason was inconclusive. Lastly, there's no reason to replace bearings and hubs unless they already damaged. In some cases, its easier and cheaper to just replace the entire hub/race/bearing as a set.

The bottom line is nearly all trailer tires suck. I had two Marathons blow out within a couple of days. They were two years old with about 10K miles. The only ones I've not heard numerous complaints about are Maxxis and Sailun. Maybe some of the expensive, commercial type trailer tires from Goodyear, Michelin, and others. I'm running light truck tires on my 5th wheel now.
