Sailun Tire Failure

"I wonder if this isn't a major CYA from Goodyear after those bad years with some of their tires."

Give GY Tech a call and tell them you are going from load range "E" that is at it's carrying capacity. Then tell them you are going to a "G" tire. Then ask them what tire pressure should you run.

They will tell you to use the chart based on the heaviest tire on each axle and add 5psi to the chart pressure.

I did this in 2010 when going from GY "E" to GY "G" tires. I ran the "G" tires at 85psi for thousands of miles with perfect tread wear. optimal braking and ride.

I have NEVER had a flat or blow out using GY US Made "E", "G" or "H" tire. I did loose some of the center section of my GY "H" tire, they replaced it.

On every tire I based psi on LOAD.

Ford and Firestone certainly didn't pay attention to load ratings back in the 80s, when they killed and maimed a bunch of people by putting inadequate tires and inflations on Expeditions, and such. Really? A P tire on a 4-5k lb vehicle, then only inflate to 28 psi? Drop a load of kids and some gear into one and, guess what? You get blowouts at freeway speeds, rollovers, injuries and death.

When I seen it in my mirror I initially thought for a second it was a bearing, it actually looked like the trailer was on fire from the amount of smoke, but could see pieces of tire flying off. IMO ,and far from an expert , I think I had lost air from a leak, and the missing section of tire was the process of the tire coming apart.

4. And almost without exception that last thing they mention is use a TPMS.

This. In my opinion, this sounds very much like a situation could have been avoided had a TPMS been used. It likely would have alerted to a low pressure situation long before the tire opened up.

They don't protect from every situation, but I've seen enough saves that it's well worth the peace of mine they provide:

Very, very true that what applies to companies/individuals that put many thousands of miles on tires in a very short amount of time, doesn't necessarily apply to many RV'ers that age out a tire before it wears out.

"***Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of the tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load carrying capacity and minimize heat build-up***"

I've had long e-mail conversations with both Alan and others at TBC Brands (the US distributor for Sailun). I am very confident they will tell you the same thing they told me:

1. The Sailun S637 tire is often sold to commerical truckers who will almost always inflate the tire to 110psi. And they do this for one simple reason - they just do not want to take the time to adjust PSI for each load. So most commerical users inflate to 110psi.

As a former commercial operator pulling heavy GN flatdeck trailers there are several reasons we use max pressures regardless of the loads. Through millions of miles we learned the hard way max pressure makes for a longer lasting cooler operating tire.

The biggest plus is something they teach in trucking schooling/classes and fleet mgrs harp on is derated tire pressures can affect the tow vehicle fuel usage. This affects bottom line which is less fuel used = bigger paychecks all around.

In this type of work we use lots of tires. I had five trailers on the road with 28 tires on the ground. Just about all those trailers may use two sets a year at 40k-60k miles per set. So we learn quick the folly of derating a tires pressure especially on a trailer.
Some rv folks like to use minimum pressure charts which may work for them which is fine ...but they also don't wear out tires....they mostly time out or come apart.

Like Goodyear tells us;
Goodyear Tire and Rubber .... weighing RVs
Special Considerations

Alan, thanks for the phone conversation yesterday ,and the inflation chart you sent. Unfortunately could not get that excel spread sheet to post correctly here on this forum.

I was unable to locate it on the Sailun website, if you could direct me, I may be able to link it to this forum .

^^^ Or simply put tire size and load rating in a search. Tire brand is irrelevant.

Blasphemy I say!!!

You mean Sailun recommends using the weight/inflation tables as GY does??? Difference is Sailun says add 10% and GY says add 5psi to what the chart says.

This just can't be. :R

Ron, just curious, where you are coming up with that 10% thing on Sailun. I have a inflation chart , the Sailun rep. sent me, and don't see anything mentioned about 10%. It does mention that the given pressures for the weights is the minimum to use. I run 100 psi, 10% would put me at max air pressure 110
