Default Keeping Hoosier tires from rotating on the rim?

I’ve had significant problem with this having the tire shop use their slippery stuff to mount my tires. If I have them balanced then the first huge braking zone they will rotate about of a revolution around the rim and suddenly there significantly out of balance again making the whole balancing operation kind of pointless.

What do people use to stop this? I’ve herd having the tire guy use Hairspray for lube but years of serious off road BMX and mountain bike racing in damp climates has shown me that WD-40 is absolutely without any doubt the superior stuff for installing grips and keeping them stuck in place. Hairspray fails quickly if it sees any moisture WD-40 glues rubber to steel within 30 seconds much stronger bond than hairspray and moisture will not penetrate the “Water dispersant number 40” and it’s also more heat resistant than hair spray

I know most people think WD-40 is a lubricant. In fact it is not. It is a water dispersant solvent.

I’m thinking of taking a can of WD-40 in and telling them to use it as lube to mount my tires. Anybody have any experience or comments?

Clean the lip of the tire (I like to wipe down with brake kleen), brush the tire lip with Permatex High Tack, mount the tire, let the P-tex set up for a bit to tack over, and then inflate. This is what most of the high horsepower drag radial racers are doing in lieu of rim screws or beadlocks.

On the new bad boy Camaro I think Chevy bead blasted or sanded the inner lip of the rim to create more friction for the tire to grip on.

Looks like the new 6ULs have anti-slip knurling to keep tires from rotating on the rim.

Did you mark them? Do they continue to work around the rim if left to keep running? We don't balance ours. So haven't noticed. Think I'll mark the stem location before next weeks runs on Lincoln concrete

I don't ballance my autocross tires so I never paid any attention with them. I've rotated track tires on the front about 3/4 of a revolution. After at track tire guy re balanced I dropped significant lap time with the vibration gone. On track speed range in my car is about 145 -40 mph, hugely different braking duty cycle than 68-35 on a typical autocross course.

Yes much different. I wasn't sure which discipline you were referring to that was spinning the tire on the wheel. We are running our race car in T1 next year. It was going about 135mph before braking into turn 1 at gateway a couple weeks ago. Didn't seem to have an issue with it. But it's only running 245s for now. Trying to get wide body approved from the CRB though so we can put 275s on it as well.

I never had the problem with track tires till I went to Hoosier and grip levels went way up over nitto/RA1's etc. running 245 and under gets me better wt/hp allowance to run just under the Limit for NASA TT2. I've done really well with it when I make it to the events. Getting close to GT2 lap times. running about 2 seconds under the T1 lap record held by Pratt Cole at Pacific Raceway.

Mine rotate. Next time I mount hoho's I'm going to use wd40 as lube rather than the tire lube. I've heard of people using the wd40 for this before. It does for sure make rubber stickier, I've used it to get another fast run or two out of improperly stored 8 year old R25B's before.

The problem is 38mm TIR in T1. But the 2554 is allowed now hopefully without restrictor soon. The other approved turbo is 3076. We will keep an eye on it but we are running Hoosiers on it as well.

When I mount Hoosiers at the Local tire shop they move due to the mounting paste. The tire shop at the track (AIM Tires) mounts them dry and I don't have an issue.

Anther option is to balance the rim and tape down the weights. Balance and mark the tire position. It the tires move move the tire weights the same amount.

WD-40 evaporates quickly too. Can't see any downside.

I dont balance my race rubber - never found it useful. Never had much vibration and its SO easy to throw a tire out of balance on the track, it has always seemed like a waste of money. I have run R6, V710, Hankooks and ATS DTC, 6UL all with no balance and no vibration in a variety of combos. Pick up a few marbles or lock a wheel for a moment and bye bye balance. Perhaps others have a different experience, that is just mine.

Same. No balancing without any issues on a number of different tire brands.

having them balanced then having them rotate on the rim is far worse of a balance issue than not balancing at all.

No rotation when I had the guys used WD-40 instead of the stuff they normally use.

Everybody wants to guess what WD40 is and no one reads the MSDS. You're pretty close.

It's 60% Stoddard solvent, 25% de-waxed petroleum oil and a few this and that's. (No fish oil regardless of what you might read on the internet. )

If it works for you to lock down the tire then done deal. But both primary ingredients are known to be unfriendly to natural rubber so keep an eye out for that type of damage. The tire glued to the rim because the WD40 dissolved some of the rubber I'd guess. Pretty much like my PVC water sprinkler system.

Thats how it works. WD40 melts a bit of the rubber and it sticks to the rim when it cures after the wd40 has evaporated.
