Saxo Boy,

No one seems to have suggested the obvious which is one (or more) of your wheels may no longer be perfectly round . You don't say which wheels and tyres you a running but the lower the profile the and the larger the wheel the more likely this is to occur.

I know this because I have a similar problem with my RB5, I went to a local garage where the guy is concerned about solving the problem and he balanced them to 0 but showed me that one of them was not quite round, compressed from hitting a pothole is the usual reason. Even then I had slight vibration, so I swopped the fronts for the rears (which I also had balance) and hey presto no vibration . Its a pain though because I can't swop them to keep wear even.

Also note that alloys will need balancing on a reasonably regular basis if you drive on roads with a poor surface and we live in Britain so you have little choice!

Can wheels be balanced perfectly? The VTS used to have 'centreless' wheels which were a nightmare to balance and you could always feel a slight vibration at certain speeds no matter how many stabs they had at it. I just accepted this.

The scooby recently got 4 new tyres and I can feel I slight vibration (particularly) on smooth surfaces at about 65-70mph. Its hardly noticeable most of the time but it does bug me! Can they be balanced perfectly or am I expecting too much?

BOB.T

Yes, in a word!

A straight wheel with a good, new tyre usually doesn't take much to balance, it shouldn't need more than about 20grams on it.

You set the machine off, it calculates how much weight you need and where, you put that lot on, spin the machine up again and repeat untill it says OK. Most machines give a tolerance of 5 grams, ie, if you're between 0 and 5 grams it classes it as OK, this is where most tyre fitters stop, you can go right down to 0 but most of the time it's not worth it.

If you're unhappy, go back and ask them to do them to 0, see if you can watch too.

I think I might take it back and see what they can do cause it was really getting to me this morning. At points I'd let my hands hover a few cm above the steering wheel (i.e. not touching it) and I could see it shuddering back and forth a bit

Mungo

A related question: is there a maximum speed to which these amchines are accurate to?

BOB.T

SB, deffo sounds like a balance problem, perhaps a weight has come off?

Mungo, the machine should cover all speeds(up to 70 of course!)

Mungo

Exactly! it's the "up to 70" that I was wondering about.
Do race tyre outfits have better machinery for balancing extremely accurately up to very high speeds?

Hi,
A wheel balanced at 10mph is the same as a wheel balanced at 200mph,when a wheel is balanced properly it shouldn't be a problem.Has the wheel been balanced statically or dynamically,was the said wheel coned from the front or the rear,these are questions that should be addressed.To have your wheels balanced properly don't take it to a national tyre company take it to an independent that actually cares if the problem is solved.
ANY PROBLEMS THEN EMAIL ME FOR ADVISE

17inch OZ supperleggaras with goodyear F1 A NIGHTMARE to balance.

Most places will let a 5gram imbalance go (and you would not notice it). 1-2 grams on the above set-up gives a steering shake. Needs to be spot on!

Chizzer,
where would you reccomend I go for Pucka' tyre balancing.. I live in Essex,

BOB.T

I was taking the p*iss re 70mph, sorry

LG John

I've got the standard MY99 alloys with 4 recently fitted Toyo's. I'll let the place that fitted them have another stab at getting it right. The car was in for a service recently and I had a Trooper 7 seater tank for the day, whilst it sucked in every imaginable way it was refreshing in that the steering was perfectly smooth......even though you had to tell it a week in advance that you wanted to turn
