Interesting thread. Never heard of this Chinese brand until now. I see the positive testimonials.
All I can say is that I HAVE experienced a front tire blow-out on a diesel pusher, and I never want to risk an unpleasant experience like that again. Taking Chinese-made tires out of the equation is my first-line of defense, regardless of testimonials.
RV tires are simply not a place to look for cost-savings, IMO, ESPECIALLY with higher gross weight vehicles. The risk is just not worth it, even WITH the bargain-basement prices.
