I will stick with GY's NEVER even a flat with 4 sets. MANY thousands of miles. Also there is the US VS China thingy.

There *are* folks on the Escapees HDT forum who have *not* been equally pleased with GY G614s on their heavy 5ths.

The China "thingy":
Mainland China ("Communist China", the PRC - "People's Republic of China") mfgr's are very capable of manufacturing tires to desired specifications.
Just like lots of your "brand name" computer stuff.

The bad vibes resulted from ST tires - which already had the bad vibes (especially GY Marathons) when mfg in the USA..:(

Trailer mfgrs used STs that met the tire specs for their product when it left the factory. The OEM STs usually were almost instantly over their load ratings when owners put their treasure in the trailers.

Also, most US mfgr's gave up on production of ST tires, as it is a "niche market" = low demand.
Mostly Chinese branded tires filled the gap - and carried the same (req'd) specs for STs.
AND - the same results (tire failures of "China Bombs") for the trlr owners..:(

*************************************************************

Michelin has mfg facilities in China - with the same quality and standards as their tires mfg in other countries.

OP - do your research on *any* brand you plan to purchase.
It's *always* easier to find negative experiences, than positive.
Which is not a bad thingy...;)

The "bad vibes" was from Marathons made in China... The GY G614 has had a pretty good record for the last 7 years or so...It used to be the "only game in town" when it came to purchasing a quality tire, (though they had their issues with them in the US)...Now there is competition with the GY G614..and the ONLY competition I see is the Sailun tire at this time..

As of now, I would only purchase tires from a manufacturing plant in China if it had met ISO TS 16949 standards.....I KNOW what goes into the quality of that tire, I KNOW about their quality and manufacturing processes and how stringent they have to be along with proof in record keeping...If a MIchelin factory in China has met the same quality and manufacturing standards, then I wouldn't hesitate to buy one of them, BUT the "no-name" ST tires that are cheaply manufactured and sent state side with NO type of Quality and manufacturing processes where I'll just "guess" they make a Quality product....no, I won't buy one unless I see credentials to where they are actually trying and achieving manufacturing and quality processes that are good enough to meet the above certifications...Most don't even try to get the TS16949 certification...it would cost too much to make a quality product with a good reputation...

So, Sailun tires , yes...a Michelin plant with TS16949 certification, yes....if not.,,then, no...This certification is plant to plant...Just because a Michelin Plant in one country is TS 16949 certified, doesn't mean one in another country can and will meet the same standards, they should..and they're capable, but it would depend on how they're pushed to do it and if they "keep the standard"..


I saw a Fusion TH at Camping World this past week, 3 axle 5er and it had Sailun S637's all the way around.....I thought that was pretty good compared to another one with 2 axles and tires I never heard of, (probably "name was changed to protect the guilty) type of thing you get with most China made ST tires...and yeah, I still believe that...it is what it is...
