Sailun Tire Failure

The quality of a factory product is just as good as the company or mgment wants it to be.

Great scouce for arguably the best RV tire out there , have a couple friends that has ordered them there, and were happy with the service, price , and the tires were about as new as you could get them

This Sailun replacement tire I had to get was only four months old , the dealers go thru them pretty fast .

All this talk about quality control is just that, talk. Folks that never worked on the factory floor have no clue about what goes on. To make a quality product it takes workers that care about what they do and that is the root of the problems in some countries. Yes, I have dealt with ISO9001 and all those programs of the month and know that many have no value, just feel good stuff to entertain those that never touch the product.

ISO9001 and it's predecessors have always been feel mgt fodder.

I'll tell you that I was super happy that GY decided to build the Endurance tire in the US. And I'm even more pleased that it seems to be doing very well. My only problem with the Endurance - and I know this is really my problem - is that I'm mad at GY for making the Marathon tire for so many years even when they knew it was a crappy tire.

The Marathons were made in the USA and were a reasonably good tire, then production was moved to China where they made junk. Next, Goodyear moved it back to the USA till they made changes in production in China. Then back to China where junk again was produced.

The Marathons were the gold standard for trailer tires until they went to China. After that, Goodyear so destroyed their brand that they had to come out with a whole new name for the Endurance tires. So far for me, I'm impressed with the performance. The sidewalls are stiff and they were kinda a bear to mount, but they are doing the job, staying cool after long runs down the highway and no obvious construction issues so far.

50 years ago, the same could have been said about the Japanese - and that is no longer true. At some point it won't be true of the Chinese - and even today, there are some high quality items coming out of China, so the process has started.

First of all, standards are only as useful as the people enforcing them. The Chinese manufacture all kinds of things. The examples of them screwing up technically complex manufacturing are so numerous as to be common knowledge at this point. Would you want something made out of a high strength steel made in China? Or something that had to be precisely machined or cast? My guess is you wouldn't. The Chinese are absolutely awful at quality control.

All heavy duty tires are going to be sensitive to inflation. Tires used for hard use have to be inflated properly or they will get hot and fail. It's not unique to the Chinese tires. It is my opinion that all trailer tires should be inflated at or near their max PSI regardless of loading.

I disagree that a tire "over inflated" for the load will necessarily wear in a certain manner. That is true for cars and trucks, but trailers are different in how the tires are loaded. Trailer tires, for example, do not turn nor is power ever applied to them. Trailer tires are basically dragged.

I also never said that ST tires are the best option for a trailer. In fact, I have been using truck tires on trailers for years, and often times, they are the best option. Most ST tires are garbage. Most ST tires are rated for 65 MPH. I am using the Goodyear Endurance right now and I am happy with the performance so far, but if I have a failure, I'm going back to truck tires.

Yes, some ST trailers have stiff sidewalls. So do all LT tires. You know what makes tires stiffer? Putting more air in them.

Chinese tires are trash. The tire that is the subject matter of this thread failed from a construction issue. Fortunately it didn't cause any secondary damage, which does happen in a lot of these cases. If I lucked out like that, I'd be so happy to only have to replace the bad tire and not have done any serious harm to the trailer.

Everyone doesn't have to agree with me, either. I spent a LOT of time thinking about this and reading when I was shopping for tires. Ultimately, I just couldn't persuade myself that risking it with Chinese tires was worth a few bucks. Losing a tire on a trip could really ruin my recreational time. I don't think it's worth it. You might.

I can certainly understand your thoughts about quality control in China.

There is an old saying, "screw me once, shame on you, screw me twice shame on me" - I might be paraphasing LOL.

Have a good evening and thanks for the discussion.

The Sailun S637 is the only Chinese made tire that meets BOTH the US import and export specs. The only one. Sailun is NOT a Chinese tire company. It is a European company that builds tires in China, much like GY, Michelin, BFG and so forth. In fact, Sailun is building two plants in NC now. We can't help people who will not do their own research instead of bashing every thing brand they've "heard" about. If the research was done, they would see millions of miles logged with these tires without many failures at all. ANY tire can fail, it's up to us to help mitigate that in the process by inspection, weighing the rig to get proper load capacity tires, TPMS,maintenance and driving the speed they are rated for. It's NOT just the tires. We have a responsibility as well.

Well said and I agree 100%.

I'm glad you posted that - thank you. It's weird that it is so different than the response I got from Michelin.
