That's speculation, since it's pretty hard to tell what happened to cause a blowout after the fact. Most are put down to under inflation, and the subsequent heat rise and flex induced blowout.

But obviously it's pretty hard to nail down exactly what the cause was. And tire makers use under inflation as an excuse to get out of having to pay for lousy tires.

If a tire is rated for 110 psi and ran less psi, wouldn't this cause a issue due to "under inflation"? Still think a name brand E ply LT tire is best bet. Ran LT's on our '06 Cedar Creek (13,800 fully loaded) at 80 psi for 12 years and no probs.


I ran Michelin XPS Ribs and Bridgestone Duravis R250s on our 12,400 lb 5er for years. Original LT235/85R16E china bombs called for 65 psi. I found that the Ribs were wearing a little more in the out edges so I upper inflation to 71 PSI and had even wear. Inflation is based on the load the tires actually carry, not their maximum inflation. In several calls to Michelin, they always stated that over inflation for the load carried can lead to impact damage and reduced braking ability.

Tires state MAX Load XXXX at YYY PSI. On passenger car and LT tires there on inflation charts that are universal across all brands for the same size and load range tire.

Along came cheap ST tires and it is my belief that inflation to max side number is just a bandaid that manufactures tried to stick on the tires, because high failure rates. Finally after many years there are now better ST tires available.

Inflation charts for ST tires seem to vary by manufacture if they exist at all, as they comply with different standards(think lesser).

Load and proper inflation is the way to go. There is a reason they make load/inflation chart for every tire.

"BALANCE YOUR TIRES! Tire shops do not usually balance trailer tires BUT if you don't it can shake the camper to bits"

X2 on this statement from another poster.

The cost is minimal and I am sure it will correct the problem.

I balance my trailer tires and run balance beads to compensate for the fact trailer drums if the trailer has drum brakes that are not balanced.

I have several times forgot and left items on the dinning room table. Even after a couple hundred miles I have found the items are still on the table.

Well I also running Sailuns on 6K axles. When I replaced the R-250's there were not alot of "quality" choices. The Sailuns were quite a bit less the Michelin XPS Ribs and Bridgestone Duravis R-238s. Not sure if I want to beta test the Goodyear Endurance, and the other ST's are JUNK.

2.5 years with an excellent record is not long enough?

Not when I'm replacing 5 year old tires. Even Marathons were good for maybe 2 years,

2.5 years and not one non road hazard failure that has been mentioned I think that's good enough.

I have two years on my Boat Trailer ENDURANCE tires. They hold air well never needing to add, TowMaster spare needs air often. I also am in and out of Salt Water constantly plus tow at 70.

Last fall, I installed a set of Sailun tires on my Montana, upgrading to G rated tires. I’m running only 90-95 pounds in the tires. They are shaking the camper quite a bit. Last week, we cravked three crock pots on the way home. Does anyone else experience this?


WAY overkill on the tires. Bet it's placarded for D tires, so E tires would have been much more appropriate. I'd say run them at 70-80 and see how it rides. Sell the Sailuns and get some Endurance.

Ditto on the "overkill"!..[emoticon]

WHY the G rated tires??..[emoticon]

Lowering the psi probably won't help...[emoticon]

Shocks are good - if you don't have them already - but not going to solve the "overkill".

Trlr in his profile = 29 ft and he had E rated tires previously.

If true - why unhappy with 'em?

(IMO X-2) Sell those "G" tires, and go back to a quality "E"...[emoticon]

This is exactly what Sailun told me when I inquired on the appropriate psi to run out ours. In fact they provided a bit of education to the different wear problems from over inflation (not just what you would expect from more wear in the center of the tire). The psi I run is less that the OP has his set at.

An FYI, I put Sailun on ours two years ago. Balance and the fifth wheel had factory shocks on each tire. A year ago I replaced the shocks with Monroe Gas Magnums when I put on a SRE4000 equalizer. Axle max is 6000, weight on the two axles is about 11,000 lbs. We haven’t had anything inside break and not one door or drawer opened since the Sailun s were installed.

At the time I was replacing two year old Marathons, GY had just come out with the Endurance so very little feedback on them. Plus, I wasn’t thrilled to add to GY pockets after they profited from selling **** Marathons to thousands.
