David,

You listed several reasonable solutions. The tires are dificult to mount because they have very stiff beads and sidewalls. So do Continetals, so do Pirellis.... That is the nature of a true race tire.

My solution when I mount the tires: wipe the goop clean and inflate. Effectiveness? 100% for the 30 tires I have used this year.

Dewhurst,

The above sampling doesn't represent the majority of the racing community. This audience is a miniscule subset.

I am glad you can summarize post, not read but....... I am not sure what you think work is, but one post about calling the scca?

But go ahead and call the SCCA if you think that is the correct approach for your issue. Tape the call and post it here so we can all get a laugh.

Thank you Michael for the process & support data. I understand the stiff sidewall racing tires along with doing it dry (sealing tires to the rim). I presume the goop you wipe clean leaves just enough on the tire area to pop & seal without a gazzillion pounds of pressure. What brand of goop do you use?

[MPR22]

I will look at it tonight and give you a report. Its more like a paste wax than goop. I have mounted on TR Motorsports and TD 1.2, TD 1.3.

Happens with lots of wheel/tires.. Solutions include buffing the rim bead with a gasket wheel. Just scuff it up some.
Smooth or chrome will slip. Lots of fancy P cars and cup cars can spin the tires/wheel.

THIS facinates me: http://aircooledtech...alancing_beads/

 

I had to have SM6's remounted and balanced twice due to excessive tire slippage this weekend.  They were mounted dry by a well informed/experienced tire wrangler (Bob Smart).   The rear tires seem to move much more than the fronts, which to me is a bit unexpected.  The link is interesting because if it works, in theory I wouldnt have to care if the tire moved, as the moveable counterbalance would adjust itself.

 

Fact or fiction?  Anyone have experience with this?  It would also be a LOT cheaper.

I had a guy change a truck tire for me a few years ago on the side of the road in Oklahoma. He threw in a bag of those beads, I thought he was crazy, but no vibration. All I was worried about was to get moving again.

No idea on race tires

I was told our tires are too small for them too be effective but it is worth a try. I use them in my trailer tires and dually seems too work well

We have used balancing beads in SM tires, they work.

 

If you mark your tire at the valve stem when it moves you just break the bead and move it back, you do not have to rebalanced the tire or dismount it. If you have a tire machine like i do, its 10 minutes for all 4.

 

I mount my tires with P 80 lubricant, (tip from Mark Bennett) stuff drys with no residue.

 

Its pretty difficult to mount SM6's dry, it can be done but they are difficult to mount on a 7 in rim to begin with.

Holy smokes!  If this works, I'm going to try it on one of my street car's tires that's definitely got a balance problem, in the interest of science of course.  Break the bead, slip in some bb's, and then refill?  How hard is it to break the bead?

Call me silly, but all I do is swap the tires side to side, which brings the tires back to the original mark...then go another race...then swap again.   I have had one small vibration since doing this.   Seems too simple...

vibrating anything=less HP

Huh?  Swap them how?  Off the rim?  As the tire moves, so does the imbalance.  If these BB's act as a dynamic wheel (actually tire) balance then regardless of whether the tire moves on the rim or not, it should balance out without putting the tire back where it was balanced originally.   As an alternative: has anyone used the Harbor Freight bead breaker on the Hoosiers?  If you mark the tire/wheel before they move, can you break the bead with that tool and "reset" them back to where the weights would balance it again?   It would suck, but it would be cheaper than paying for mounting/balancing after every session.

 

EDIT:  I get it now...you put the imbalanced tires on the opposite side of the car and hope the tires slip the other direction towards "balanced" again.....eh....no thanks.   OCD would overrule me.

Anyone frustrated by this problem can simply ship me your new tires.  I will cycle them in several times and when I return them to you (at no charge) the grip characteristics of the tread will be a better match for the grip between the bead and the wheel.  You won't have to go to any extra effort to get the tires to stay in place on the wheels after you mount them.
