Anyone scuff wheel beads prior to tire install?
I seem to remember some racers doing this to help minimize the tire moving on the wheel. I'm trying a new setup this season using C6 Grand Sport front wheels all around. They're comp grey and glossy all over. Figured I'd hit the bead areas with a scotch-brite pad before taking them to my tire guy. Good practice or waste of elbow grease?

After I documented my tires moving up to 180* on the wheel, I had my tire guy start using less lube when they mount tires for me. I have wanted to clean the beads for a long time, but my normal mode is to drop off the wheels/tires one weekend and pick them up the next.
In the research I did last year, scuffing the bead helps.

I marked one set of tires last year and 3 of them moved maybe 1/4". The LR moved like 7". The only reason I brought it up is because these wheels are glossy even on the barrel and beads vs. most wheels that don't have shiney paint in those areas.

Could be the difference in where we tested. I did my testing at CMP with a set of sticker As on the Z06 wheels. After one session, the fronts had moved almost 90* rotation under braking and the rears had moved almost 180* under acceleration. Meaning, the fronts and rears rotated in opposite directions. They moved a bit more after the second session and then did not move again for the weekend.
In talking to my tire guy at Discount and reading around the internet, the group-think is that the tires move in the beginning due to two factors: 1) lube in the bead and 2) jarring them when the tires are still cold. The first factor can be reduced by dry-mounting the tires or at least using less lube. The second can be reduced by warming up the tires before stomping on the brakes or nailing the throttle. Which, btw, heating the tires also helps evaporate the moisture in the bead lube.
In either case, I feel pretty strongly about scuffing the beads and keeping them clean. But seeing how much my tires move, that is also why I feel balancing a track tire is not all that important.

why not media blast?
might also want to google for images of the nissan gtr rims. I believe the term they use is knurled bead, but I bet there are other names for it...

You guys are making waaaaaaay too much work out of this.
My 888s used to move 4" in a day on my CCWs until I started mounting them with hairspray as tire mount lube. Go ahead laugh, but it works great for lube and the tire will stay where you put them till they cord. Now that's on a track car, not a drag car.
Yes, I use the extra hold variety. Seriously, it works perfectly.

Maybe we can get Aquanet as a sponsor.

FWIW, that is the standard for installing hand grips on motorcycle. After sprayed the id, easy slide on, wait overnight and its good to go. You will have to cut it off when you want to remove it later.
