Are Sailun Still the Rage

[masterdrago]

I'm considering switching to a "G" rated tire but I currently have 15" wheels. Looking at new rims and tires. I've had good service from the S637 Sailun tires when we had a 5r. Not real sure about the GY 225 x 15 on the trailer now as I just had a separation on a not overloaded 65mph tire dated 0222 showing no deterioration.

Should I still consider the Sailun considering the need for the new 16" rim? More load peace of mind.

Hope they are still good. Just bought a set this past week.

Why would you need load range G tires on a trailer with a GVWR of 7,850 lbs?

I clearly would not "need" that level of tire. The OEM Goodyear have a load capacity of 2,830# and the most weight on that tire (right rear) has scaled at 1,875. My thinking is more margin.

The Goodyear fail could have been a catastrophe had the tire come apart. It did not and I did not know the separation process had begun until I took the tire to a small town tire shop. All I noticed was elevating temperature (to 112°) and maintained pressure (86psi - same as the other 3). The other 3 were running ~95° in 86° ambient. When I got backed into the RV slot, the TST alarm sounded indicating 70psi.
I put on the Westlake spare to support the trailer and aired both to 80psi. Next morning the Goodyear was @63psi. I just thought it had a leak. The tire shop guy showed me the bulge in tread. Discount Tire confirmed the separation 2 weeks later. Goodyear will warranty out the remaining life (~1/2 or 6 years).

My point in rolling on stronger tires should be obvious however somewhat overkill.

Hope that helps,

One more thing. B4 our next trip, I'll be replacing all 4 Goodyear. Maybe with same. Maybe with 16". Still on the fence. Why I was asking.

Going to a "G" rated Sailun could, possibly COULD, result in a harsher ride, but I don't know that for certain. I ran 16" "G" rated Sailun tires on our last triple axle toyhauler. I weighed each tire and had a max of 2,500 lbs. on the tires, so I was over-tired, but I ran the tires at 90-95 psi, and they wore well, the ride didn't seem to be especially harsh, and they still looked good at 6 years old.

But IMO, it's hard for me to tell if the ride is harsh or not, unless things are flying all over the place inside. YMMV

I know I'll be adding 80# to the trailer, as those Sailun tires are ~20# heavier per tire. I would most definitely run them lower than max psi since the load is much below their rating. Just looking for something more dependable than the "E" rated GY.

The "G" rated brand "X" tire I drove back on (637 miles), I ran at 80psi, had a fairly consistent temperature of ambient + 5°.

I've also taken note that the Sailun ST235/80R16 has a lower speed index than the GY.

Here is something I just discovered pertaining Sailun Tires....
Looking at ST S637T, I see their 15" tire which I've been unable to find - 4120722 ST225/75R15

But going to Sailun S637 (Trailer) Trailer Tires Online | SimpleTire, all I see are the 16" tires.

masterdrago, take a look at Carlisle CSL 16. They make them for a 15 inch wheel. They maybe pricier but you could stay with the OEM spect wheel. The Saliun 637 is designed a lot like the CSL 16. I use Discount Tire because of the nation wide availability if service is required.
Best Regards

I'll likely be running the 637's we just bought at 80psi. Like you...I just want a tougher tire..and the Sailuns are cheaper than the GY. At least they are in Canada YMMV.
Yes the Sailuns do have a lower speed rating. How close are you to the GY's 87mph rating when cruising?

For 16" rims go with Michelin XPS LTs and don't look back
