Driving me Insane

[Mohi]

I just had my v6 15" stockies changed to 18" alloys with new tyres .
Everything was fine until i drove on the freeway. There was alot of steering wheel vibration around 110-130kmph mark ,first thng came into my mind was Balancing out , took it back to the tyre place , they redid it for me, next day on freeway again and when tried it ,was still there.
So was back to them, they said the disc had high point in them ,so they machined the disc and rebalanced my car. all the rebalances were free.

thought would be fine. but was on eastern today and ITS STILL THERE Dont know WHY..............?
All four wheels were checcked for any buckles but all were good.

Dont know why this is happening...

I have Drivin around 8000ks with these set of wheels and tyres but never experienced this becoz never use to go above 100 , but now go to melton and have to go to 110 and this drives me nutsssss.

PLZ all my mates, flood me with information , as i got a day off tomm ,so i could fix this shitty trouble.
My setup is

Rodney and jane wheels
Rockstone tyres (23/40/18) with 39Psi
Also there is little bit of leak from the Driver side end seal from the steering wheel rack(i think its the end seal. could be center as well) but i am not sure , because the oil only drips froom the left boot cover of rack.

I read somewhere not long ago someone had problems.. He got new tyres and his troubles went away.. Might be time for a new set of tyres.. ? I cant guarantee this will help but yeah.. Different tyres.. different speed ratings... etc..

Really sounds odd to me.

Maybe try putting 15s on the front and 18s on the back to see of this replicates the problem, if not try the other way round.

It could be that your suspension components are worn and it's pure coincidence.

Maybe check the tyres for bulges too

I thought that would be, as mine is lowered on stock shocks with king lows , but had mine checked when they had it up on the hoist. my car had done round109000ks in total,so i am hoping the stock shocks are not bad , as i ride my car solo.

Out of balance or out of round tyres is my guess. Talk to BJ again.

[rx2_freak]

could be those cheap tyres you mentioned above. bung your steelies back on and drive down the freeway, see if that helps.

Take the car back and look at the wheels on the balance machine and see if the tyres are running true. I had a set of cheap tyres on a car when I bought it and they moved side to side as the wheels rotated and also if you looked at them from the edge they moved up and down with respect to the rim. I ditched the tyres.
Apart from that the hole in the centre of the rims that fits over the hub is the right fit for the car, ie not too big and missing the spacer rings they sometimes use on non genuine rims?

It could be the width of the centre line/groove on the tyres?

hey mate i got the same problem as you... ive got play in the steering rack (about 3-4mm) which seem to be causing it so you might want to check it

Had the same problem with mine, swapped wheels front to back, problem solved. I suspect one of my tyres is slightly out of round...

Thanks mate...
How did you got it checked , so do i need to go to a mech or can i do it at home by jacking the car up.....

[Mohi]

Finally the tyre place checked all the tyres and wheels but found no fault and rebalanced and then checked twice , it has improved alot but there is still a bit between 115-120kmph but goes away after 120 , i dont knw why...

[Verynice]

roadstone are crap, are they unevenly worn?

[Scruba]

I had similar problem. Under 100 was fine. Swapped front to rear and then changed the tyres = all good. The tyres were out of round.

Replace all 4 tyres and go from there. Try getting a better brand tyre as this will certainly make a difference also.

[Chrisvyss]

the new ring road bypass at deer park exagerates the problem its a crap section of road and vibrates the hell out of the wheels

[calais24/7]

Probably the tires mate, i had the same problem on my vl. had like 5 alignments and balances from 5 differant shops, abusing all 5. then i bought new wheels and the problem was gone lol

[Mohi]

Finally got it fixed..had the tyre shop to take the tyres of the wheels and rotate the wheels only . And its all fixed now.

[Antsmash]

I had a similar problem recently. I was missing the center locating rings in the middle of my Rims. They're a rubber ring the stops the rim from moving around the hub (I think).

[VR38]

Maybe they are crap tyres, if the bob jane guy is trying to balance an out of round tyre it will still vibrate on the road as the tyre still follows its shape, the tyre needs to be machined back to round and the wheel rebalanced to compensate.
FWIW there are not alot of tyre shops that machine tyres as tyres in this condition should not leave the factory before correction but alot do end up on the cheap end.

Morla of the story, dont buy cheap tyres. They are cheap because they are crap.
