Featuring an extra-wide solid shoulder and mirrored tread design, the tire resists damage caused by high-scrub applications and promotes a long, even wear life.

Ratings & Reviews

Sailun S637

I researched trailer tires and now know more than the tire dealer. Trust me I have the RV disease. When I swapped my old E-rated tires to the new G-rated Sailuns I removed the wheels and tires and drove the rim/tires to the dealer. So I got to feel how heavy each new Sailun tire was over the old Westlake tire. I believe the old tires were around 33 pounds each and the Sailuns are 63 pounds...nearly double! In fact the installers had a very tough time getting the new Sailuns onto my old rims as the new tires were VERY tough. I did verify with my rim manufacture that the rims would hold up to 130 psi. Sailuns are 110 max. I have since driven 4000 plus miles on the Sailuns including through the intense southern Utah heat and have had no issues. The Sailuns are rock solid and have improved my trailer's handling. Also the original tires were not balanced from factory so after the new Sailuns were installed and balanced I have no doubt my wheel bearing with last longer. PLEASE buy these if you need a strong tire! Go camping and stop worrying about your tires!

Put these ( 6 ) on a heavy travel trailer ( 37', 17000 Lbs dry ). Then towed for 400 miles. No issues, I mounted them myself and used balancing beads. So no long term report, but better than the stock16" dry rotted tires. Steer type tread, so it tracked like it was on rails, even when getting passed by tractor trailers, I expect the front set to wear soonest on the passenger side ( 3 axle trailer ) so lots of scuffing on turns-

We ordered these tires when we were buying our used trailer. They arrived quickly to the dealership and they mounted them. They handled very well on the way home across the the country, Iowa to Texas to California. The weather was over 100 degrees and the tires never got too hot. The ride is smooth. So far they are living up to their reputation. Dealing with Simple tire was a great experience. The customer service was super. Delivery was very fast. Definitely will use them again.
