I have been using Sailun Tires on my Large / Heavy RVs for many years. They have preformed great for many trouble free miles

I've had these tires on several trailers and never have had a problem, I will continue to buy them in the future.

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.

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.

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.

This makes my second set of Sailuns and are superior to anything I have had in the past. Just an overall great set of tires.

These tires are heavy hauler long life

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

Bought S637 for my 5th wheel. After approximately 4000 miles I noticed one of the tires was bulging throughout the middle of the tread. It was not over-inflated. The other tires are still good. The warranty/return process is complicated. Now I tried ordering a replacement and "out of stock". Pretty disappointed.

We purchased/upgraded to these tires for our fifth wheel trailer. The stock tires had a flat spot on two of the tires and where not rated highly. Most stock trailer tires are rated 65MPH. These are rated to 75MPH, not that I always drive that speed. But we travel full time in our rig so if we have a long travel day I can push the speed a bit.
