What "Data" do you expect? Vibration analysis?

You realize OPR will quickly off-balance a "balanced tire" right?

There was no reason for that harsh comment. I think you misinterpreted OP's reply.


As for the original question, for AutoX, that's probably ok not to balance, but for track, at 120mph, I would definitely not take the chance and would balance them.


Where I live we get lots of snow, and sometime it gets in the Wheel, and when that happens, the vibration at 60mph can be scary. To the point you have to stop and clean the wheel.
Of course that's a lot more imbalance than a clean wheel that's not been balance, but still...

"Data" he is looking for is people with more experience in the matter then he sharing their personal preferences so that he can see what everyone else is doing and based off majority and his own personal comfort level move forward with a somewhat informed opinion.

Not the harsh responses you give, this is how you treat people when they thank you? Wow

Lot's of help and data, thanks

Don't mind him, hes pretty slow =P.

It also comes down to your rim condition. If the wheel has a slight bend to them, it is worth balancing the setup as it can be really out of balance (+2.50 ounces worth). You don't want that kind of vibration at 100+.

Best advice I can give you is to make sure you mount your tires well in advanced to your track day. I've seen guys mount up the night before and completely throw off their balance as the tire moved on the rim from the lubrication not being allowed to dry first. This is true for balance or not balanced. You'd be surprised how imbalance just a tire can be outside of being mounted to a rim.

lol, I see that he is slow. But thanks for the info, great insight on tires. I'm sure someone else will use this info.

A good experiment to do is mark your wheel/tire with some sort of removable marker. You'll be able to see if the wheel has slipped at all and rotated on the wheel itself.

I do not balance my slicks. Once you complete 1/4 of a lap and pick up even a small amount of rubber you'll realize that your time was wasted. We only balance stickers on our Lamborghini Huracan Super Trofeo.

EXACTLY!


I just had brand new hoosiers mounted & balanced for my track car.
When I loaded them on the trailer after a day of racing each tire had about 2 extra pounds of "Clag" ( rubber picked up from the road) on each one. Balancing a true road tire is good when brand new but doesn't really mean much after a few hot laps.

The other thing is that you only really feel balance when steady cruising at 70-78mph. You're never in that situation on the track, or at least I hope not. Haha

I've been tracking/instructing for 15 years and I have never balanced my track tires. Like others have said your never at a steady speed so you effectively drive thru any vibration.

If you don't put some sort of heat tape or thermal barrier over the wheel weights they have a good chance of falling off at the track anyway.
