I've return more than one new set of slicks due to them taking more than eight ounces to balance them. I have seen a bunch of slicks that were out of round as well as having severe heavy spots on them I was told by one of the west coast racing tire reps that those problems are usually cause by the factory workers taking them out of the molds to soon and letting them set on the tread part of slick making them become mess up like they are, out of round and a bad heavy spot IHTHs

I thought i had fixed my vibration on my 67 cuda. New mark Williams shaft, changed pinion angle, new wishbone. Now, just to be safe, i bought a bubble balancer to check the REAR SLICKS (brand new Goodyear) and it took “26”ounces to balance one tire. The other tire was almost as bad, 16 ounces for that one. I know many of you don’t balance, but the tire installer said he’s sure the goodyears (. And maybe the tubes in them) are defective. I’m awaiting his tear down tomorrow and opinion of what’s wrong. I was running 10 lbs air in the slick and have about 8 passes on them. The vibration shook the entire car, it was bad. I think my problem all along was defective tire and just pissed away 1200 on a new Williams shaft. Any of you running Goodyear have any issues with them????
Thanks 16 ounces?!?!?!? 26 ounces?!?!?!? Those should go right back to the vendor. Another thing to look for that I see all the time is out of round or egg shaped tires. You will feel that in the car and no amount of balancing will cure it. Needing lots and lots of weights is an indication that the tire(s) will more than likely be out of round, too. A spin balancer is key to finding the out of rounds before too much time is spent on them. Any significant out of round is a no go for me. They will never get any better and no attempts at balancing will cure the vibration that they cause. I nearly quit buying MTs over these issues and was a big part of my decision to go to the 275 drag radials rather than the 295s. All of the 295s were just about unusable. At least I can find 275s that don't totally shake my fillings out. And bolt up your wheels to the car and check that run-out, too. I have seen aftermarket axles and rims that were terrible.
Master, again and still

I bet its not the tires, its something with the balancing. Both being off that much......26 ounces on one?!?!? Never do that, figure out what is wrong.
All the years I have raced I never seen any slick from the big 3 take any more than 8.
I bubble balance mine with a cheap harbor freight balancer. Been doing that way for years.

Thanks to all of you that gave me your thoughts. The guy that repaired the horrible balance job and sells Hoosiers, not Goodyear, (he does pro stock and pro mod balancing at NHRA events) told me the tubes were twisted in numerous spots. One of them he said was really bad. After he installed new tubes, one tire took half an ounce, the other, an ounce. That sounds hopeful to me, but I don’t think I’ll buy Goodyear anymore. I always had good luck with Hoosiers. Yes, I do have my fingers crossed. As I side note, I took the tires off because I noticed that one slick had no weights at all, it was the 26 ouncer. If you set this tire on the ground, it would roll away from you.
Thanks again

We sent them back! The most I have ever ran on a slick is a pound which to me is way to much weight.

I always balance slicks simply because the balancer is right next to the tire machine I use to mount them so it's a no brainer for me. We have a really nice road force balancer at the dealership where I work that also measures the exact tire diameter as well. Gus

For those who religiously balance their slicks have you ever put them on the balancer after a couple races?

after installing any tubes in any tires take center out of valve stem and fill and let out air many many times to untwist any twisted tubes, yes I know you allready know this I always dump lots of baby powder I my slicks with tubes. Never had a problem with twisted tubes. Also used a harbor freight bubble balancer.

For those who religiously balance their slicks have you ever put them on the balancer after a couple races? I didn't re-balance after I started racing them but I did swap my slicks side-to-side after every race weekend. (Also checked brake adjustment.) Slicks can and will move to varying degrees but it seemed like less as time went on and I didn't run tubes. Tubes require screws or beadlocks. I did mark the slicks in line with the valve stem and swapping them helped move them back closer to where they were when balanced during the next weekend. But if you have the time & resources, periodic checks/rebalancing is one of those "nit-picky but good ideas. I balance my tubed 14x32's (PITA) when I bracket raced a well as my no-tube 9x30s in IHRA Stock. A good friend and very successful 10.90 racer owns a tire store and they always balance all race tires. The Hoosier rep at the races did too. Even if you don't feel an imbalance, especially in lower pressure slicks, it doesn't mean the imbalance isn't there. It can affect the tire as well as the suspension and driveshaft. You don't want any "forces", however slight, affecting the "tune" and job other parts on the car are trying to do.

I talked to a friend at the races this weekend that makes M/T slicks at Indiana Pa and asked his opinion. He said every set of slicks should be balanced.

I read every reply. Maybe I missed it, but I never saw any downside mentioned to balancing.

All these different opinions. Fascinating. I’ll keep balancing. Thanks for all your expertise.

Slicks with tubes? Baby powder, inflate and deflate a few times. I stopped using tube decades ago. Some people still do. I'm a weight fanatic. If I can take that weight out of a wheel/tire assembly, I do it. Balance. Most time a few ounces tops is all they need. Otherwise, take it apart, rotate the tire and repeat. Re-balance every few dozen runs or when ever it picks up a vibration. Driveline and wheel/tire vibrations are very different. I've ridden with driveshafts that were put together by idiots. 7500 in the lights and everything is a blur. These old machines did a good job.
If the results don't match the theory, change the theory.

Where they land is where I balance them because mine are glued on with high tach.
