I just got a used blaster and spining the tires with the bike on jacks it sounded like rockes in the tires or even like bb's rolling in there. Is there some trick of the trade that i dont know about? Or how the heck does rocks get in both tires?
 
old school drag racers usedto put bb's or ball berrings in the tires to 'help traction' by keeping weight on the tread where it makes contact with the ground...

sure your not hearing the berrings rollin around in the carrier?? if the berrings are junk the balls will fall out and roll around

The sound is defanatly inside the tires on the rubber. sounds just like bb's rolling, not like rocks that would tumble.
 
i'd have to see that to believe it, that sounds insane, rocks get in the tires but no air escapes,
that's some kind of chris angel mindfreek sh*t right there i tell ya, i saw him throw a playing card thru a plate glass window once without breaking the glass, hahahaaaaaa
 
idk man you tell me how that sh*t gets in there.....bought the tires mounted brand new from RM nothing was in them when i got em and they have never been off the rims to this day
 
I'll bet its dirt. Dirt will get in through the bead and with the spinning of the tires the dirt will turn into little balls. I've had it happen from racing mx during the summer
 
could be the back side to the valve stem [it may have broke and the last person put new valve stems in without retrieving the old ones] . . . just a thought
