When I got the golf it would shake when hitting around 100km/h. Was informed this was because of uneven tyre wear.

Put 4 new tyres on the golf, they were balanced when fitted, but now the car shakes at lower speeds, usually when accelerating. Shakes pretty bad around 30 - 50km/hr in 2nd and 3rd gear. But once I'm over that speed its fine. Still shakes a little around 100 but not as bad as the lower speeds.

Ideas?

Cheers.

PS. This is Sam Cooney's old Golf if that helps.

Does it have after market wheels? Do they have center bore locating rings?

Yeah its got after market wheels. The wheels aren't hub centric. Would that cause vibrations that bad? Its a forum members old car. He ran these wheels for a couple of years with no problems.

Certainly will, get some hub rings, cheaper than new tyres

I ran these wheels for like 2 years with no issue. It bolts locate it, theoretically and legally for a low volume vehicle (ie a car) they don't need to be hub centric.

If it only just started after changing the tyres I'd be questioning the balancing job?  :-\

But I mean you can't go wrong with hub centric rings anyway if you wanted to give that a go too

I have a feeling it has something to do with the fitting too.

Wasn't that bad before I had the new tires put on.

The bolts wont center it 100%, theres a chance who ever re fitted the wheels could not have them centered

Nope, if you have bolts you need to have a hubcentric set up.

If you have non-hubcentric wheels with a VW style wheel bolt setup, you'll more likely than not get at least some vibrations unless you install the wheel with a tool designed to keep it centred as the bolts are tightened.

As far as I know, you won't pass a cert with non-hubcentric wheels on cars like ours. But hub centering rings are so inexpensive, it's not a problem. I'd recommend getting metal ones rather than plastic though.

Yep I've passed 2 Certs with non hub centric wheels, and I asked to make sure it was okay.
He said low volume vehicles need either one or the other, the rings or tapered bolts

If for no other reason though, having the wheels hub centric makes the wheel like 100% easier to put the wheel on!

So you can get away with it for tapered bolts but not ball seat? Interesting.

Even with tapered bolts, you still often get vibrations without hubcentric rings - I've noticed it when trail fitting wheels etc before sorting rings.

There are many reasons cars shake.
I would get the center rings as they are so easy and then you know. I had non center fitting wheels and they went from terrible to fine depending on how careful I fitted them.
I also suggest an alignment.
If you take a car to a shop and say its shaking and they fit new tyres and its not better you can take it back and they will check the balance and then fit the wheels better if needed or tell you what you need and order the rings if they are a good shop.
The end is nigh, but the end of what is the question?

Thanks,

I went back in today and they had a look. They seem to think its caused by not having the rings as well. They didn't have any that fit and said they will need to be custom made, costing around $30 each.

The size is 57.1 - 63.1

Get em made, or jack the car and crack the wheel nuts and then very carefully center the wheel and tighten the bolts a little bit, then use a screwdriver and your eyechrometer to see if you can make it even better and then tighten and see if its better. It is is it cost you nothing.
I was supposed to get the rings but I carefully fitted my wheels and I was running smooth as silk ;)

Been there had that,get the hub rings and forget your problems after that,about $20-25 per set usually.

I found I could wait to get rings made or just get my car going good right there and then.
But by all means the rings are good.
You can get them straight tho without them.

All sorted. Thanks for the help from everyone! And cheers 00quattro00 for cutting me some rings! Champ
