I'm not your dude dud and you can get your facts right, your not even worth the argument[>:]
Dude Get your facts straight before you post. Foams absorb shock from jumps and bumps and keep the tire from squishing down to the rim and also to build up the side wall of the tire so when in a turn the tire dose not want to lean on and roll on the wall of the tire. they also help with handling cuz they help stop body roll
if you had a brain you would be dangerous[:-]
