I have the 17" TSW imolas on the V6 now, and lovely they look too. However, I have a horrible feeling one of them is bent. The car is smooth and fine till you get up to about 60mph, then a distinct vibration starts to come through, first steering wheel, then as speed get up the wrong side of 75 it gets bad enough so you can feel it through the floor.

Now then, the question, the wheels have been correctly fitted by a national garage, they have been balanced twice now and still the problem persists. The guy who re-balanced them noticed there was a dink on the front left wheel, like it have been kerbed. Not big but there. Is it likely the rim is bent?

And why didn't the garage see this?

Also, given they road tested it and said it was better after re-balancing, is it just my imagination?

I went out with a mate tonight who said he could feel the shake clearly. I'm talking steering wheel vibrating shake.

Know this is getting abit long but does anyone know a good wheel straightener in East Anglia?

Cheers pal!

Is there any known way to check them, like you check brake discs for run out?

Jack the car up and spin the wheel with your head under the car. Any wobble should be obvious...mine was!!! It was worse than I thought but drove perfectly...go figure.

Any decent engineering shop specialising in alloy materials should be able to play about with it. Just had the buckle taken out of mine but the dint is still there, however the balance is ok. Dont fancy putting it on as the up and down wobble will not do the shocks any good....hammer time :D

Andy try swapping the wheels front to back ....

and see if its any better if its only slightly distorted you might not notice it when its on the back

Or you could try getting them balanced on the car

Be a bit careful doing that, though. It may feel better but if the wheel is still wobbling due to it being out of sorts, you could end up knackering your wheel bearings over time with the stresses set up by the vibration.

Just a long shot - you don't have cheapo tyres on it do you? When I was even poorer than I am now :rolleyes: , I used to use cheapos. Could never get rid of the vibration, no matter how often they were balanced.

I was thinking tyres too. Maybe the "kerbed" wheel has damaged the tyre slightly ????

my friend has just had the same problem with cheapie tyres , also is it being balanced on the car? if not i take it you have a nice heavy locking wheel nut that goes on and messes it up a bit.

Here's a long shot for ya:

If it doesn't show up whent he wheels are balanced off the car may be the vibration is on the car itself? Could you have an unbalanced brake disc or drive shaft?

Swap the wheels and if to continues at the same corner then it ain the wheel!

Most wheel refurbishers have a straightening jig, if that's of any help.

Check the wheel to see if it's out of round, if you thumped it somewhere.

Jack that corner up and then get an axle stand with a ruler strapped to it and place it so the end of the ruler just touches the leading edge of the wheel rim.

If you rotate the wheel through a complete revolution the ruler should stay the same distance away from the rim. A bent rim will see the gap opening and closing. Do the inside wheel rim as well as the outside.

Also check the actual tyre isn't out of round, even if it's properly balanced. Use the same trick but this time with the ruler touching the tread of the tyre.

My money is on the tyre being mis-shapen or not seating on the rim properly, especially if it's a cheaper brand.

Okay, the saga continues.
Had them all straightenbed on Saturday by Kevin at Alloy Wheel Repairs in Melton Mowbray. They were ALL buckled slightly, only on inside edges, all came out okay. However, now the tyres will need to be taken off and put back on because they were round on the bends.

The tyre fitters didn't see fit to tell me, or notice a 5mm deviation from round on one wheel.

Kevin said that all after market alloys are weak as ****.

Ho hum.

Oh yeah, just noticed the wheel bolts are now too long. Will grind 5mm off the ends so they bolt up tight and proper. They run out of screw thread on the front wheel hubs.

Wish I had left these the hell alone!

WELL WELL its funny how things go,MY mate Steve Brem has just handed me his alloys as he recently hit a pothole--thats a long story,the upshot was he had to buy new alloys so on that note I decided to get my silver Speedlines painted the proper black colour so Ifitted the only two left from Steves car low and behold they had a dunt(bend) on the inside rim also then fitted some old 164 wheels and tyres to use my silver ones for refurb-- turns out all but one of my speedlines have dents in them which also explains why one was loosing pressure all the time between them all only two are undammaged !!!!!!!
So its not just after market ones that are soft,more like the roads are just shite thesae days!! Alfapat :mad:

Andy, you say they are too long on the fronts ????
Sounds like the spacers have gone walkies at the wheel straightners. Did they take the wheels off ???
Maybe the spacers were stuck to the wheels and they have beem removed. Check the back wheels to see if the spacers are stuck to them.

As you probably know, the spacers were only fitted to the front wheels....

The car hasn't got spacers of any sort, but the wheels (original 15" Alfa Speedlines) fitted fine and sat right in the arch. The new wheels have a slimmer bolt area depth. Therefore the bolts (35mm) thread is now too long. I assumed the car never had spacers as all looks well.

However, as I am often told, I know nothing at best and very little at worst.

Ho hum

Have a really good look. It is strange the rears are OK and the fronts aren't. I spoke to a Jason77 recently and he had always thought his car had no spacers (although info showed it should have). He realised it did when he changed his brake discs....the spacers had become part of the discs so to speak.

Mine were the same, the joint between the spacer and disc had become covered in a layer of rust and couldn't be seen.

Just a thought?????
Should my 2.0 16v have spacers?
Was driving in the 75 behind the missus in the 155 and noticed the rear track seems to be quite narrower than the front! Is that supposed to be like that?
Haven't noticed any spacers, will check this weekend!
