Trans force HTs on 3 different tow vehicles and 2 different trailers. All loaded heavy, wouldn't use anything else at this point. 8 years experience with them
My 2014 Ram 2500 came with Firestone Transforce HTs. I have very few miles on them so far (under 500), but the ratings (3650# per tire on my truck) seems stout enough.
Had TransForce AT's on my old truck, and TransForce HT's on our old fiver. Just put Transforce HT's on our new-to-us truck, and are about to put a set on our new fiver. Have always worked well for us, and in my opinion is the best bang for the buck out there.
I have Transforce AT on mine. I like them and they are great for towing. I just replaced mine at 98K miles. Bought my truck used so I don't know what, if anything, was on before the Transforce. I have used them for about 30K miles.
