The Sailun S637 tire is a versatile regional all-position tire for commercial trucks and special trailer applications. It features five extra-wide ribs for exceptional stability. An extra-wide solid shoulder resists damage caused by high-scrub applications, while a mirrored tread design ensures even wear. Wide grooves are designed for hydroplaning resistance, while a long-life rubber compound is engineered for extended tread life.
Specifications
| Specs: | Value: | Description: |
|---|---|---|
| Sidewall | Not Available |
Describes the sidewall appearance. Examples: BSW= Black Side Wall, WSW = White Side Wall OWL = Outlined White Letters.
|
| Load Index | 143/141 |
The load index (LI) is a 2 or 3 digit number that corrolates to the maximum amount of weight the tire can carry. For example, a tire with a load index of 87 indicates that the tire can carry a maximim load of 1,201 lbs. In the case of our example the 87 identifies the tires ability to carry a maximum of 1,201 lbs. So 4 tires will carry a maximum of 4,804 lbs. Refer to your vehicle owner's manual for the recommended minimim Load Index. It is not recommended to install tires with a lower Load Index. By doing so, this could cause your tires to be overloaded thus potentially causing a blowout.
|
| Speed Rating | K |
Speed Ratings (SR) are based on laboratory tests and indicates the maximum speed the tire can achieve. These tests are based on limited time trials. Higher speed rating tires typically will yield better handling capabilities, but may often result in lower mileage. Refer to your vehicle owner's manual for the recommended minimum Speed Rating. It is not recommended to install a tire with a lower speed rating as it could affect the handling of your vehicle. It is important to note that speed ratings only apply to tires that have not been damaged, altered, under-inflated or overloaded. Additionally, most tire manufacturers maintain that a tire that has been cut or punctured no longer retains the tire manufacturer's original speed rating, even after being repaired because the tire manufacturer can't control the quality of the repair.
|
| Load Range/Ply Rating | J/18PLY |
Ply Rating is related to the max load capacity. This value can be defined with a letter or number. The higher the number/letter, the higher the load capacity.
|
| UTQG | Not Available |
To help consumers evaluate their tires, the U.S. National Highway Traffic Safety Administration (NHTSA) created the Uniform Tire Quality Grading System (UTQG). The UTQG rates tires are rated on their tread-wear, traction performance, and temperature resistance. The grade for each of these can be found on the sidewall of your tire (except for winter tires and certain light truck tires).
|
| Max Single Load(lbs) | 6005 | The maximum load this tire will support. Remember to multiply this number by the number of tires installed on your vehicle to get the maximum carrying capacity. This number is directly related to the Load Index. |
| Max Single Air Pressure(PSI) | 125 | The maximum air pressure this tire will support. This does not represent the amount of air pressure your tires should have at all times. Consult with your owner's manual to determine the best air pressure you should use for your vehicle. |
| Tread Depth | 17.0 | The amount of tread on the tire. Once the tire is worn to 2/32nds, it is considered fully used and should be replaced at that time. Most tires will have tire indicators in the grooves of the tire to help you determine when the tires are worn down to 2/32nds. |
| Tread Design | Nondirectional |
Nondirectional - most common, same tread pattern on inside & outside of the tire. Can be rotated to all four corners of vehicle. Asymmetrical - tread pattern is different on the inside to the outside of the tire, and must be mounted properly. Can be rotated to all four corners of the vehicle. Directional tires - roll in only one direction, must be mounted properly. Once mounted they must remain on the same side of the vehicle, and only be rotated front to rear.
|
| Rim Width Range | Not Available | The approved wheel rim width range this tire will support. |
| Measured Rim Width | 6.7 | The recommended wheel width as recommended by the tire manufacturer to get the best wear us performance for this tire. |
| Section Width | 9.7 | The measurement from sidewall to sidewall. |
| Tread Width | Not Available | The measurement from one side of the tread to the other side of the tread. |
| Overall Diameter | 31.1 | The height of the tire when fully inflated. |
| Manufacturer Part Number | 5547971 | Manufacturer part number (sku) |

Truck tires on line
Great tires and a fair price
Monteburnam
Very good tires
Only have about 1500 miles on the tires but so far they are meeting expectations. Four stars as i can’t speak to their long term performance @ only 1500 miles.
M Reed
Theses tires are great
Great price and showed up in a couple of days
Peter
I really like these tires on the rear axle of my class A motor home!
Even though I install "premium US tires on the front axle" I am super happy with these Sailun tires on my rear axle. They are real quite, hold the road and my wife likes them!!!!! So far after 2000 miles we are very happy and would recommend these tires for purchase!
Bruce Woerner
Great Price (made me nervous) but So far - so good
Have less than 1,000 miles on the new tires. I hauled my 36'-foot, 15,000+ pound 5th-wheel from Richmond, VA to Tampa, FL - these new tires rode smooth - no problems. Checked other reviews on these Sailun S637 tires - most all were positive. The price for these tires at tires-easy.com was about 1/3 the cost of the Michelins that were on the 5th wheel when I bought it. I was in VA for work - tires were delivered to my hotel in a couple days - got them installed locally no problem. I would definitely use tires-easy.com again.

Great Road tire No Go off road.
These Tires are working great so far I have only put 2100 miles on them but this is about to change in a big way. From the out dated old tire to these new tires was a night and day experience. I have fine tuned the air pressures to the wait of my RV and the ride is so smooth. I drove about 250 mile in the poring rain with no problems at all . But I have not owned them long enough to give them a true evaluation but I will update this in time. new trip will be about 13,000 miles round trip I will know these tire after that.

Tires are awsome
Great service
Mike M
These tires are great.
I bought these tires to replace the Goodyear that were on my RV. These tires are great, much better than the Goodyear. Will replace these when I have to with the same tire and the price can't be beat compaired to the Goodyear.
Mike Wiese
Tires seem to be in great condition, haven't used them yet.
Great price

They arrived on time and look to be of good quality. My only concern is that the date code shows them to be 9 months old. Hopefully thet will be fine.
