ST tire threads reminds me of Fords 6.0/6.4 engine debacle.
Yeah its not just the fact those ST tires were made in china as evident we had the same issues with ST tires when they were all made in the USA. Being a niche tire and a low volume product there wasn't pressure from the feds to make them more reliable and in line with a P or ST tire on the same trailer.
There are some excellent made in china ST/P and LT tires.
The industry is improving the ST C/D/E tire's finally. Goodyear knew the Marathons were not reliable as evident of the new designed Endurance.
Same with Carlisle terrible Radial Trail ST tire line which. Carlisle came out with a new designed with the RH series and now the HD series that look more like a automotive tire.
The Providers are another new gen ST tire that has been around since the '00-'01 era with no reports of across the board issues like the old ST maypops.
And the new gen 16" load G commercial grade all steel carcass such as the Sailun S637.....and other load G poly carcass tires.
ST tires are finally showing improvement. We all can benefit from them.
