The Sailun S637 tires generally receive positive reviews for their performance, durability, and value, particularly for use on RVs, motorhomes, and heavy trailers.
The Sailun S637 tires are generally well-regarded for their performance on RVs, motorhomes, and heavy trailers. They offer a good balance of durability, comfort, and value, often outperforming more expensive brands.

Excellent performance and handling in various weather conditions. Smooth and quiet ride. Great value for the price compared to more expensive brands. Durable construction with steel belts and sidewalls. Good traction and stability, even with heavy loads. Improved ride quality over some OEM tires. Suitable for long-distance travel and highway use.
Negative highlights
A few instances of premature tread wear or separation. Poor performance in snow and ice conditions reported by one user. Slightly larger size may cause clearance issues in some vehicles.

Sailun S637 - good quality & durability
Sailun S637 215/75R17.5 tires have a good reputation for durability and quality made tires. This is my first time running these on my trailers but they look good, have fresh date codes and no issues with mounting so I expect they will live up to their reputation. Simple tire has the best prices and free shipping can't be beat.

Best Heavy Trailer Tire
I wont look anywhere else for trailer tires on my 5th Wheel. I bought these to replace the same model tire that was currently on my Toy Hauler and they are fantastic. I had over 15k miles in about 2-3 years on my last set and had 0 issues. I plan to use this brand and model for the foreseeable future.

good tires so far
These tires were put on my fifth wheel camping trailer in 2021. After about 14,000 miles and two years I can say that they have held up very well. When installed they went on easy and balanced without a lot of weights. The tires are a heavy duty tire and they weigh 64 lbs each. The tread shows very little wear and appear to be wearing evenly. I cover the tires when parked for a week or more to protect them from sun damage. At this time I can say that I would recommend these Sailun tires.

Great HD trailer tires
I bought these trailer tires several times over the past couple years, because they have a higher speed rating than the Ironman tires I had used. I load them to the max and then pull them over 250 miles. I was having blowouts with the Ironman tires and so far these tires are holding up well. I have had a blowout or 2, probably due to not monitoring tire pressures as closely as I should or road debris, other wise very happy with the value of these tires.

I haul my Excavator with these tires I needed the most extreme duty tire and these tires met that
They have an all steel cord
75 mile per hour tire
125 PSI
They are "non eco" If you buy a lot of tires that's a good thing
