Peculiar Tire Problem

[Matt42]

I'm having a problem with a 9. 50-R-16. 5 Michelin tire. It's not on my diesel, but on the trailer I pull.



Maximum inflation is 80 psi. When I pull on rough gravel roads, it will lose about 30 to 50 pounds per day. On just rough roads. it'll lose maybe 25 pounds. Once I drive it on decent pavement, the leak slows down, and just ends, and it holds pressure just fine.



Any ideas? Rough bead surface on the wheel? I am cornfused!

Sounds like bead surface problem. I would have the wheel checked also and if that is not it have them check the bead surface and remount.

Sounds like the bead surface is rusty or dinged up. Cheapest fix is to have an innertube put in.

I am going to speculate...

That the valve stem is leaking. The extra vibration=extra air loss. Just my opinion. Soap it up and wiggle it to find out.

Could also be a cracked wheel. Only lets air out when flexed. Strange problem though. Let us know what fixes it.

I plan to have the tire dismounted next week to check the bead surface area, and maybe clean and repaint it. I will also watch for cracks. I don't know about the stem. We've tried that, and it's on its fourth. These wheels get the most gawrsh-awful use, hauling a gravel testing plant into some gawrsh-awful areas.
