I ran RIBs for 40K+ and 6.5 years then R250 for 4 years before selling that trailer. I liked the tread and cost of the R250's over the Ribs. Both are great tires as a LRE LT tire. The Sailun S367 is a great LRG tire, and our new BH came OEM with them.
BTW I sold the used Ribs for 200 bucks on CL. Chris
Both are a commercial grade all steel ply carcass tire and both are recommended for trailer use by Michelin and Bridgestone through emails....1-800 and their dealers. Both are the holy grail of LT E tires especially all type of trailers including rv trailer so you can't go wrong with either. Tirerack.com shows the LT E XPS Ribs at 266 bucks vs 213 bucks for the R-250
The XPS Ribs are a commercial grade truck tire that are also certified by Michelin for use on trailers. I don't think the Bridgestones have that rating.
Gonna start an argument... We prefer Sailuns, We are now on our second set on the 5'er, haven't had a problem with them after 2 round trips cross country +. Going to put them on the truck in Nov. Good Luck and Happy Camping !!
Duravis R250’s are great tires. 15k miles through everything from snow, scorching heat, many a back roads, and no problems. Still looked brand new when we sold the 5r.
I run Michelin's on my truck without an issue in 20 years. I had the same dilemma as you a couple of years ago. XPS or R250. I went with the R250's because they saved us about $ 250.00 . I have no regrets at all . Excellent tires .
