As I was checking the pressure in my old beat up 38" TSL swampers I noticed that the dry rot is to a point that air is leaking out the sidewall (the square indented area the Swamper lettering is). Upon seeing this I thought blow out, but not sure. I have an hours ride to reach my club's weekend adventure spot, which within an area of no cell phone service (so I can't ask them about it). ANy feedback? Am I asking for a blow out with dry rot to the point that it is leaking out the side wall? Thanks! ~ Russ PS- At the moment I do not have a spare, I just upgraded to 3/4 axles and 38s.
