Hey guy's I went to replace my tires on my volcano.So when I took the tire off the rim.
The foam inserts was just nasty,all tore up and dry rotted.So I took my son's old bike
tire innertube that had some hole's in it.I cut it so it would fit in the new tire's,the length I mean.
I then stuffed it with new foam,and it looks like a small innertube.It fits perfect in the tire,took
some working with.

Far as how much foam to insert and making sure the foam was evenly in the tube
and around the inside of the tire.Got the back tires on my jato,since the volcano is not running.
It rides great,nice landing when I jump.I tried to take pictures but my camera wont connect to
my computer right now.So when I get that going I will post some pictures.
