Another China Bomb Tire?

Just purchased a slightly used 2019 Heartland Big Country 3155RLK 5th wheel which has Westlake GR890 G14 tire with a date code of 2917. Never heard of them and suspect they are the typical poor quality tire put on most new trailers. Has anyone heard of these and have any comments. If indeed they are one of the so called "China Bomb" tire then will probably replace with GY Endurance or maybe the Sailun 637's.
Thanks

From the online posts Westlake seem to be an OK tire. At three years old I certainally by spring would consider replacing them. What axles? What tire size? If you have 8K axles I would look into upgrading to 17.5 inch tires. The entire package probsbly would not cost any more than the GY your looking at.

I would replace them also, and get the new ones balanced. Makes a huge difference in the way the trailer rides and the tires wear.

Then go with any LT tire. Michelin xps ribs are popular

The Westlake G rated tires actually seem to be pretty good tires. The E rated Westlakes? Not so much. No way I'd use those on any rig. I'm going to run the Westlake G tires on my new 5th wheel until they are a couple years old then I'll replace them with Sailun S637.

etrailer.com had very good reviews for the Westlake G rated tires. So will probably use them until at least spring and then, due to 2017 date stamped on tires and they were setting in Las Vegas, will upgrade.
Thanks for the help guys.

When I researched tires I did not find anything to suggest poor quality or defective tires in the last 10 years. If it has a DOT stamp it has to meet US standards.

I am not a tire expert but from what I read the factors in tire failure are over loading, under inflation, heat, and speed.

From what I have observed in the Lost Wages area is that there is a better chance of winning big at the casinos that finding a rid that was not overloaded, driven too fast on a hot day.

All the 'consumer' reviews are good at that site.

I had an OEM Firestone tire tread separate on the first trip in my new '74 IH TRavelAll. Took it back and got the usual prorated jacked up price song and dance. I mentioned that the Consumer Report article. Oh that is a different tire they said.

I said never mind. Since you think it is ok to endanger my family and rip me off, I will keep the tire and send it to CR. Pulled out a camera and asked if the would stand next to the tire.

Got a new tire for free.

To be fair, this trip was with my lead foot father. After graduating and being commissioned in the navy, we did the camping road trip thing. He had some unkind things to say about small town cops. Well dad if you did not come into town doing 80 mph maybe they would not follow us through town.

It was my turn to drive while being supervised closely (I was 25) and I noticed a slight out of balance vibration and pulled over. The tire had not failed yet but I could put my had between the treads and tire.

I think tires have improved greatly in the last 40 years but they still will fail.

The "problem" with LT tires is that they are not made to withstand the side loading and twisting forces the ST tires are designed for.

HORSE PUCKY! My 13,500 pound fiver came fauctory equipped with LT tires. Ran LT tires under it for 12 years with zero issues. LT tires work just fine under any fiver as long as the tires are rated to handle the load. With 7000 pound axles that means any LT tire rated to at least 3042 pounds.
BTW Michelin XPS Rib is rated for trailer service.

I replaced my Westlakes on Day One with Bridgestone Duravis R250 16" tires. They're a ribbed comparable to the Michelins but a few dollars less expensive. You wouldn't believe the difference between them and the Westlakes--much heavier, thicker sidewalls, much beefier tire.

In the 4 years they've been on our trailer, there has been no issue.

Anyone that says ST tires withstand more sideway scrubbing better than a LT tire simply does not know what they are talking about.

I replaced ST China Bombs after I had a blowout. These China Bomb tires had a very flimsy side wall. The China Bomb tires weighed a lot less than Michilen XPS Ribs that I bought to replace them.

LT tires are used on a lot of trailers now. Airsteam for example.
