Marathon Blowouts and Question

[Harry Womack]

I use the load range E tires at 70 PSI. I have not had any problems and the tires do not look low like the load range D tires that blew out.

What brand/size E -rated tire would replace the 15" Marathons on my 3023? I haven't been able to locate anything but d's.

The service bulletin information I cited also says, "Do not exceed the maximum pressure for the wheel." What might that be?

The wheels are stamped 85 PSI max. I am using the Maxxis M8008 ST225/75R15E 10 ply tire. Maxxis # TL15713000. I got them from Discount Tire for around $125.00 ea.

My Goodyear Marathons were stamped either 50 or 55. So adding 10 psi above 65 mph makes no sense at all.

[Harry Womack]

Load Range C tires are 6 ply with a max pressure of 50 PSI
Load range D tires are 8 ply with a max pressure of 65 PSI
Load range E tires are 10 ply with a max pressure of 80 PSI

I thought I remembered reading something about that just couldn't be for sure. The Discount Tire guy Recommended I consider E rated tires in the future because he had seen very few issues compared to D rated since trailers are easily overloaded.

Hm Interesting no other structural issues?

They also had Carlisle in an E Rated Tire & recommended it over D Rated.

That being the case, since my tires are stamped 50 psi, then the must be load range C on 14 inch wheels.

I'll check them tonight if I don't forget. But, I no longer have Marathons. I have Tow Master.

Wayne usually your tires will have the load rating on them also.

Example: 225/75/15-D

Good point.

I do know, from the one time I weighed the axle, that when full loaded, more than I ordinarily carry, it weighs 3380 on the axle. I have never weighed each wheel, so it could be unbalanced.

If anyone ever held a rally near home (San Jose) where they weighed each wheel individually I would be interested in attending,.
