I put Hercules tires on last summer. About 4000 miles on them and no issues.
They are 14 ply so a little heavier than an RV tire. They ride fine, don't seem stiff, handle wet roads really well and show no signs of wear. They are a summer highway tread so I suspect snow traction would suck but I don't intend to drive in snow.
I am happy with them. I gave up mentioning them on here as there is a lot of bashing of anything that is not Michelin or Goodyear and I don't need the abuse.
I find the negative comments never or can't provide any proof that the tires perform any different than the "name brands" from a safety point of view, only myths and opinions.
As far as buying local -- I bought them from a local dealer and had them installed right here in my town at a local truck shop. They were brought here by a local teamster and stored in a local warehouse until the dealer ordered them so it's not like the money disappeared into a sink hole. Every business that handled them made some profit.
Do your research and if you are happy with what you find then buy them. Bottom line, only you can decide what is right for your situation.
