People who call Tires "Chinese bombs" are either unaware that the product has changed or they just want to knock Chinese products. The Towmax STR is a new product that now has a nylon cap like the made in Thailand "Mx" brand for higher temperature tolerances.
I just had installed four Carlisle Radial Trail RH also with the new nylon cap.
I would check with the store and make sure whatever brand you choose has the nylon cap. I do not think the Omni or Gladiator does, but I am not certain.
I do know that Westlake ST tires do.
You should be fine.
