Tire Balls

Attatched is an interesting picture. This was the 9a 450r quad, Mike Cafro`s team. Not sure who is on the bike at the time. Eric Shaun and I were checking out some pics and we came across this one...... Notice the tires, front and rear. We all know at high speeds tires stretch, ALOT! Also, Eric brought up a good point, with the inertia of the spinning wheel along with the "tire balls" themselves wanting to eject themselves from the tires at high speeds. I think these are a great innovation, but have heard good and bad about the vibration, or out of balance at high speeds. Would like some opinions on these if anybody has tried them. Dean, maybe you can get the tire ball guys to explain on this forum???? [img]images/graemlins/wink.gif[/img]

This was at the Score Baja 500 2004.

Re: Tire Balls

just gotta pray they are installed right, so at least you dont ahve to worry about them vibrating your bike apart

now about the tireballs wanting to come out at high speed, there is an easy fix to that....go slower [img]images/graemlins/grin.gif[/img]

Re: Tire Balls


Wade Summers who invented the Tire Balls will be at Vegas to Reno. I am sure he would be available to talk on Thursday at contingency. He will be around the Temecula Motorsports van with Mike Cafro.

Re: Tire Balls

I talked to Wade at tireballs about that picture and the 500. Here is Wade's response:

Great photograph taken by Trackside Photos.
By the shadow and crowd I would say that is Danny Prather. The shadows highlight the presence of Tire Balls in the tires. About half way through this event, a vibration developed which we felt was attributed to several punctured balls.
To be safe we changed all four tires at the bridge crossing down south (sorry I don't know all of the names yet in Baja). As it turns out there were 3 failed balls in one rear wheel, but the vibration was caused by a bent axle.
Vibration can occur when generally more than one (ATV) Tire Ball fails and all are close to each other. While in this condition the tire still isn't flat, the excessive vibration makes the rider slow down.
There is no vibration (out of balance) if all of the balls are inflated and filled with the same volume of air.
Having each ball filled with the same volume of air (we use nitrogen) requires following a procedure which gradually brings up the volume in each ball gradually, similar to torquing the head bolts. If however the Tire Balls are filled one at a time up to the final pressure in sequence, the first ball will have a greater volume than the last ball, this can cause an out of balance condition. Reading the instructions (or watching the video/dvd) will help the installer understand the importance of the inflation procedure.
Incidentally, Brian at Daryl Smith Sand Tires is testing a manifold which inflates all of the Tire Balls at one time. If this works, we will build a system and make it available to all of our customers.
We want (encourage) feedback from all of our customers, especially those that have installation concerns or operational issues. We work hard to make improvements to installation, however we may not be good at getting everything we've learned out to our customers. That is why these forums are so valuable to all of us!
Thanks for the good work and I look forward to seeing you at the Vegas to Reno.
We will be mounting Tire Balls at the Maxxis rig at contingency row all day on Thursday.
Wade

Re: Tire Balls

Thanks Dean, thats exactly the kind of feedback we are looking for. Right from the Manufacturer. This gives everyone access to the question concerning vibration and a little insight on how the Tire Balls work.....If anyone who uses them could post here on how they like, or dislike them....Could get a balanced(no pun intended)perspective on this....Thanks for getting that posted on here!!

Re: Tire Balls

Our TireBalls worked great at VTR. Last year we had 5 flats,this year we had none. Wade personally installed our balls the night before the race, and we had no vibrations at any point from them. I heard though that Ed did get a vibration from his. Don't know yet if it was just because they had some balls punctured like Wade said, or something else.
We will definatly continue to run ours!
Thanks Wade for installing ours!

Re: Tire Balls

Hey gang... same here ... the vibration got worse at pit 10sh. I have to get he tires from Richard and break them down. We suspect that a few of the balls got puncured so we are currious. We didnt have any flats either.

Re: Tire Balls

We had vibration start coming from the rear right before pit 10. Then again from the front right before the finish. We haven't broken our down, but from the outside, it looks like we lost a couple of balls in the rear. The tire has 3 pretty good slashes in it, so they probably kept us from doing 3 tire changes. I'm positive that we flattened some in the front because the front left tire is really deformed. Again, this probably kept us from having a few tire changes in the front. When the tires start vibrating everybody starts complaining, but if you think about it, if it wasn't for the tire balls we probably would have to of changed 6 to 8 tires. This way we only stopped for tires changes 1 time.
