So I did a lot of research on Sailun tires and overall, they get decent reviews. A background check on the company reveals that it is all Chinese, including manufacturing, marketing and R&D (handled through a Chinese University). Despite the comments in this forum, the Goodyear G614's are better rated overall - but they are MUCH more expensive than the Sailuns. (Not a problem as far as I'm concerned - there is no price that's too high to insure safety.) Like I said before, it's a new coach and we'll see how these tires do, but at the first sign of a problem, hello Goodyear.
However, I do have a question. From towing trailers of several types, I always knew that those tires were rated at 65mph. However, for some strange reason, I thought that these larger, high pressure ST tires would be rated for higher speed. Wrong. Still 65 mph.
What's the general consensus and experiences with running these things at 70-75 on a regular basis when conditions and limits allow?
