Slicks out of Balance

[nova10sec]

Well I had a problem today. Last time at the track I had a bad vibration on top end, thought it was due to my slicks not being balanced. I tried to balance them today, both tires either have belts that broke, or just were bad. They shook the machine really bad. I tried spinning the tire on the rim, then removed the tubes, nothing worked. These tires are new, less then 5 passes on them.

I am wondering if I got a bad batch of tires or if I have overlooked something else..

They are Mickey T's 28x11.5 slicks

[RadialNova]

Just a suggestion, What about a bad u-joint? I had a vibration top end and it turned out to be a bad u-joint.

[nova10sec]

I have new 1350 ujoints. The tire are definitely shot, it a matter of did my cars setup destroy them or were they just from a bad batch...

Geez and you said you have 5 or less passes on them? I think I'd call Mickey Thompson and talk to them about that, Unless you were doing burnouts on the street they shouldn't wear that fast.

[Real McCoy]

Contact M/T and tell them your story. If they had a problem and are willing to help you out, they'll tell you. RM

Tread wise, they look new, they just are unbalancable... So hopefully M&T will stand behind there product. Thanks..

Any New News?
Did you Call Mickey??

that sucks!!!!

[nova10sec]

Obviously, I feel the pain personally. Overall I do see the potential impact of extended warent. to a non covered product.

If they did cover it, a racer somewhere else who may have had a problem now had basis for similar coverage and or litigation.

So I guess I am saying "It suck to be me right now"

When you say they couldn't be balanced, what exactly do you mean? Were you using a computer balancer? Were they round?

[nova10sec]

Yes, they required so much weight, I think it was 330 grams, that I could not balance them.

I've never balanced mine :confused:

[nova10sec]

I have never balance slicks before. I only tried after they vibrated so bad. On the bid end, the car shook so hard I could bearly read the gauges

Holy sh**!!!!!! Never had that happen before :eek: :eek: :eek:

LOOKS LIKE GOODYEAR OR HOOSIER HAS A NEW CUSTOMER!!!!!!

[nova10sec]

I ran Hoosiers last year, like them.

[David_D.]

not that GoodYear or Hoosier won't have a new customer, but something tells me they won't warranty the tires either. ;)

[furball8994]

I think you just got a bad set. One othe posibilty may be to low air pressure.

[ladderbar64]

could it be a ring and pinion problem?? had a 72 chevelle that when I was at the stripe shook the car really bad also. needed new gears and problem solved . had a chipped tooth

[straightaxlenova]

Do you leave the car parked on jackstands, to keep the slicks off the concrete? Once I had a problem with a flat spot on the tires from leaving the car parked on underinflated slicks. Ever since then, I always keep jackstands under the frame. It also helps save your coil-over springs.

I don't drive my slicks on the street. When I get home from the track my street tire go on, and my slicks are in the garage. If anythingI take more care tehn necessary. I usually get 100 solid runs out of a set.

How would a bad ring & pinion make the tires shake when they are removed from the car and installed on the balance machine?

[Seattle_Mike]

That's what's making it so hard to figure out! :)

[1975ssnova]

Here is a possible answer ,Buy a new pair and send back your old ones.

[skrymir]

Here is my suggestion. Big puddle of bleach and burn em till they are round again :)

[Nova_Guy]

I had a set of the old Pro-Track tires, the first company to come out with the soft compound street tire. I had them ballanced by my buddy; he told me a normal tire would be returned they were so out of balance. He used over a package of the stick on weights to get them true. Normal drive on weights wouldn't work, it required way to many.

[novaboy009]

My big M/T Indy Profiles were a b**** to balance as well. My tire guy says that most slicks and drag radials are really out of balance...

I wonder why?

[DriveWFO]

How can you balance a tire that deforms the faster you go???

[Seattle_Mike]

They are like a Thermos...it just knows whether to keep it hot or cold! How do it know?

[the FLYER]

not that i know anything about slicks, i don't... but how can the weight of a tire deform ??? it deforms on heigth & width, but that'd be it, right ??? it's on the rim in a permanent location... so whatever imbalance there is will stay in the location it's in, in its mounted location... i'd think anyways...


watch the wording too guys, no bashing, remember ??? ;)

The weight ain't changing, but if you move that same weight further/closer to/from the center of the wheel in one location (not uniform around the tire), won't that make it out of balance?

like i said Dave, "I know Nuthink !!!"

i dunno... if it's outta balance "X" amount here, i dunno if the tire gaining diameter as speed increases would change balance that much... it out here, it's out there... i'd think. i'm learning about this too, so don't take what i say as fact, just thinking out loud and learning ;)

[David_D.]

If the tire is out of balance, tire growth shouldn't affect it. You're still slinging the same amount of weight around, just in a larger circle.

I could be mistaken, but I'm pretty sure the pro racers balance their tires. I know that they do in Pro Stock anyway.

[rods65post]

I had some 10 x 28 M/T's on my Buick Regal I wanted to balance them and they where way off and I thought it was the wheel or something. Then I bought a set of 9 x 28 Goodyears and barely had to put any weight on it at all. This was on a 8 inch Weld wheel and I was ticked because I thought the wheels I bought were junk. Maybe it was the tires?

[1975ssnova]

Did the guy trying to balance them try to move the tire in to a different spot on the rim, IN example turn tire half a turn on the rim ? I use to work at sears auto when i was younger and this trick worked pretty good on some tires /rims that were way off balance.Also we use to have a machine that would take a out of round tire and grind/remove rubber to make it true .I did not like the machine myself because you are takeing a brand new tire and removeing a quarter of the tread to make it round.But it is an alternative other than throwing them out or replaceing them.Also do not use bang on weights,use stick ons.You can stack them on eachother and you wont throw one at over 100mph and take off someones head at the big end of the track.

The set of M/T's I have on my car now at first needed a ton of weight to balance them. I noticed that there was a dot on new M/T's and so we broke the tires back down and put the dots by the valve stems and the weight required to balance them went way down. I don't know it the dot is in fact supposed to line up with the valve stem, or if it was just the fact that we moved the tires around some, but whichever it was, we had no problem balancing them after that.

[furball8994]

I think you hit it right on the head. Most tire's have a "mark" of some kind that is supposed to be lined up with the valve stem. Most younger tire guy's don't know or do this. I have a set of M&H 28x11's on my chevelle. When I had them balanced they needed a lot of weight. I check, and had the guy line them up and 1 was dead on and the other 1 only needed 1/2 once.

[teddisnoke]

I just had on Sat. my Phoenix Slicks balanced for my racing on Sunday (yesterday). I noticed last time an imbalance vibration, so I thought I'd have them re-balanced.Holy cow! One of them needed nine ounces! Unexplainable? I did keep the weight's on, but painted them to blend with the tire as I was embarassed. It looks funny, but it worked. No more vibration. I'm kinda scratching my head on all this stuff too with balancing slicks?

[Nova_Guy]

If you run slicks with tubes as most require them. If the tire won't balance I was told to put baby powder in the tire before the tube then mount the tire. Fill the tire up until it pops on the bead and let the air back out. Then roll the tire around drop it few times to get the folds out of the tube. Then refill the tire. I pulled my Pro-tracks off and there was a huge folded over spot on the tube. I'm sure it caused a large heavy spot on the tire.

[novalty]

This is probably a stupid question, but had to ask just the same. Are your rims in decent shape?

Paul a.k.a novalty

[nova10sec]

I spun balanced the rims alone, they were really close to dead on. I tried rotating the tire on the rim, also removed the tubes, the tires just have heavy spots in them, extreme heavy spots requiring 330 + grams to balance.
