Well thats what my wife said.But I sware I can here rocks in my rear tires. They have never lost air or ben off the beed. So how did they get in there? Or is it just the rocks in my head?

Or the rocks in your pipe. They could have been in there when you had the tire put on.

 

It might be rocks in the exhaust. And if you say its from your tires then if you ever put fix-a-flat in your tires it might be that because if you let your quad sit in the cold over night it freezes in the tire and when you pull out it breaks into peices and probobly hits the in side wall and sounds like rocks hiting it

 

Mine has something in the tires also. I think its from going down dirt roads and pitching it sideways they get in there some how

 

It's small chunks of rubber inside your tire. Over time tiny chunks of rubber ball up and get larger inside your tire, they all do that, don't worry!!!

 

Thanks guys. It's not in my pipe,I took the tire off the quad (not off the rim) and shook it. It had more of a "tinky tinky" sound than a "thuddy thuddy" sound. Thats why I thought rocks. I havn't poot fixaflat in them so its not that eather. Im not to woried just curious.

 

Actually it is little ***** of rubber in your tire, I took the one of my 300ex and they had about 5 good size rubber ***** inside them each.

 

yep.... its rubber. its actually in there from the very beginning. it comes from when they make the tires. whether they get bigger or not over time I don't know. but mine had them in their from the very beginnning.

 

I had that happen too,I took the tire off the rim and there they were...a family of 4 with their entire bedroom set.I evicted them on the spot.

 

I have something in the factory tires that sounds like a ball or rock and always wondered what that was. Some truck drivers put 5 or 6 golf ***** in their tires to reduce vibration and to help balance them.
