I just had Bridgestone Duravis R500 tires put on my Mountaineer and one of the installers came over to me and asked why I was putting these tires on instead of trailer tires. Are these tires ok to run on our trailers? They told me they were commercial truck tires, now I'm confused.
That is the exact tire I run on my Montana and the exact tire I have installed on several other Montanas along with numerous other SOB 5th wheels. I do tires for a living and if I thought ST rated trailer tires were better I would use them. You didn't make a mistake.
