wheel balencing second opinion required please

[bortaf]

I have a customers car in at the mo to solve a severe vibration on the car, now 2 of the wheels have 140 grams of balence weights on em and are still out of balence, i know they are out of round and so fooked, the question is what is an acceptable weight for a decent wheel? i usually say over 35grams and there's a deeper iassue with the wheel or tyre but what do others concider an aceptable amount of wheel weights ?

cheers

P.S the car in question is fully poly bushed including the Xmember so any imbalence will seem worse but i just weanted that 2nd opinion before getting the customer to spend £500 odd on a new set of wheels and tyres, i am trying to get him to drop a few poly bushes from the car as i know cortinas suffer when fully bushed

Have you tried moving the tyre on the rim ?

[Savvi]

Wondering how old the tyre is , could it be blown and gone out of shape ?

[bortaf]

tyres are 2 years old (decent make) tried moving them round but you can see on the balence machine the wheels are not round (if you lay on the ground and watch the wheel you can) wevery time you add the weight the machine says tyou need the imbalence moves and it need more we got to 145 grams on one wheel and i said give up it aint gonna balence out and if it does it'll weigh twice as much as it should

 

 

 

shame cos they look good (minilites)

[GT_lenny]

can't you just bung some steelies on and have a nip down the road in to 100% condem the wheels?

[bortaf]

Done that cheers mate just wanted peeps thoughts on an aceptable amount of weights TBH

there's still a small shake with the steels but they are old and have slightly tracked tyres and not been checked for balence but certainly way better than the alloys

My opinion is the alloys are fooked, well at least 2 are it's just convincing peeps that a wheel can be balenced and still not be 100% when on the car at differant speeds to the speed of the balance machine personly i tend to think that more than 35grams on a wheel indicates a problem that may not dissapear even if the machine says it's ok, i did work in a tyre place but when i say it was quickfit it sort of doesn't help me sound like i know what i'm doing and TBH it was 20 years ago tyre and wheel tech has come a fair way in that time and really wanted somone with fresher knolledge to give me an opinion

[GT_lenny]

i may be misinformed but i thought more than 100grammes was illeagal?

 

whether it is or not i've got to agree with you no amount of weights will "true" a bent wheel

[vibrating_Cake]

ive seen worse, my cousins runs the same "base" of 145g, and then it goes up in a pyramid of 4 layers of weights on top of eachother.... finally then it was balanced.

dont see the problem to be honest, aslong as the tyre seats .

but i wouldnt run them wheels haha, i get annoyed when theres any wheel weight whatsoever on my wheels nvm that many!

[AlanN]

I had 85 grams on an really old Wolfrace slot and the guy said its not unusual for really old rims, but don't bring it back with your shagged bearings

[100e pard]

Id say depending on the size of the wheel, the acceptable amount differs

 

I regularly balance 18" + wheels and draw the line around 120g then still advise the customer.

 

On a 13" I wouldnt like to go above 50g

 

But im no profesional

[supersport]

depends on the machine and when it was last calibrated. i take it that was done with a dynamic balance? try a static one and see what that comes up with.

at work we usually go 2 about 100g before the customer gets told they need a new wheel but i think thats more they want the money for it than anything but then again people who have audi's generally either have the money or dont give a crap!

[bortaf]

cheers chaps

they are 13's 2 of the worst have flat spots on the rims inner and cos the car's fully poly bushed it makes it sooo much worse trouble is of the 2 good ones 1 of em nned weights right on the inner lip where they hit the caliper

The thing i find is that even if it comes up as balenced on the machine once you get to over 60 it vibrates like a Bstd (polys not helping here), i've tried differant hubs/discs and bearing and the vibration on the rear is in some ways worse than on the front (no steering movment to absorb the vibrations).

still he's going for a new set and new tyres so it will be sorted it's just i said i personly dont like more than 35G each wheel cos thats what we used to work to back in the day and i wonderd if it was still around that mark?

thanks for the input

[bigdaz27]

Looks to me as if they have been balanced wrong. You shouldn't have the weights opposite each other like you have, if say you spin the wheel up and it says 10g and you spin it again and its says 10g in a different place then the first weight was put in the wrong place, as putting the weights opposite each other give a false reading. Also some tyres hare a little dot on them thats ment to be lined up with the valve if its not. this can make it out of balance

hope this info helps

[bortaf]

Right here's trhe final outcome, stripped of all the weights and started again, result- exactly the same (as i knew it would be like i said the wheels are out of true and no amount of balencing will iron out an out of round wheel).

sooo i put the tyres on an ald set of sports steels i had laying about, result- worst old whhel was 155g and still unbalenced on the steel 35g (this tyer also has a flat spot), 2nd worst 145g - on the steel 30g, 3rd worst (flat spot on the tyre from long term parking) 25G, last one went from 35g on the alloy to 2g an the steel, so there you go just cos the machine said it's balenced i aint allway so !

P.S the car drove like a limo compaired to the old wheels even though there is a slight vib from the flat spotted tyres on the rear, so next time you buy those lurvly minilights take care !! you might get bitten, this has cost the customer £100 on top of the purchace price and he still needs to spend £500 on a new set of wheels and 2 tyres, oh and dont park your car for months on it's wheels
