Every time I run in deep mud my right rear tire goes flat. There are no holes in it and I can fill it right back up with no leaks until the next time I hit the mud. I do notice a few bubbles coming out at various places where the tire meets the rim, but only when I'm pumping them back up. And it stops when I shut off the compressor. The tire and rim are only a couple months old. Anybody ever heard of this? Any ideas for prevevting it?

 

I have heard of this somewhere before...dont remember exactly where but what I do believe happens is that the mud gets between the tire and the rim and then dries...when that happens there is room for the air to escape from the tire...dont know what you can do about it but that is my theory (from what I have read) of what may be happenin

 

Try breaking down your tire and look for mud on the bead, if there is any clean it off, soap it and reseat the tire. This worked for me had a leak and almost put tubes in , no prob since.
