ST tires vs LT tires.

I had a "tire man" tell me that all ST tires are made in China. I'm not interested in unsupported opinions, but if someone actually knows if this is true or not, lets hear from you. I use Firestone 10ply LT tires on my trailer.

Looks like your quest for answers to your where are ST tires made took the usual ST vs LT debate turn.

JFY at one time some years back all ST tires were made in the USA by our domestic tire makers. And we had the same type of problems with them as many do today.
The ST is a niche tire like our agriculture tires or industrial tires or lawn and garden tires/etc with low volume and low profits. Just about all niche tire production was moved out of this country. Most now are in china or other asian rim countries.

Firestone tires in a 16" LT E Transforce H/T have been tops with RV trailers and commercial haulers for their trucks and trailers for years.
