rear tires are scrubbing like a biatch

[Paiste402]

the insides of my rear tires are down to the wires and the rest of the tire is new. Not nice when tires are $150 a pop for cheapies, what has to be done to avoid this? its got 17's on it, 235/45 tires on the rims.

cheers chaps.

Your rim offset is probable wrong.... Do a search for your cars standard rim offset..... and check it..

[HoldenOnn]

* What car? The EF Falcon in your details?
* Does it have IRS?
* What pressure are you running in the tyres?
* How do you drive eg spirited on take off, or light throttle all the time, cornering hard?? etc etc?
* How low is your car from factory ride height?
* Have you had a wheel alignment....if not, why not? If so, what was the reading on the rears as far as camber reading goes?

A little/lot more info would help you get any sort of decent help champ.

sounds like camber mate

Guessing its been lowered?
All commodores get it just gets much worse when lowered cause of severe camber

[jashdown91]

yeah thats certainly camber. the only thing that will cause the insides of your tyres to go bald is some chronic negative camber.

oh sorry guys, ive just gotten a VR commie. yea its got IRS too and not lowered

yeah its the camber, stock IRS commos get bad camber after a few km's. nothing a camber kit can't fix. unless it's unusually bad as a result of abuse. eg. hard take offs and ripping skids often. haha

check centre rubber mounting that holds the diff up to the body, suspect this has worn out and has now caused your wheels to run on an angle at the back, it would be very obvious stand about 10 metres away from the back of the car and look at angle of rear wheels, if rear wheels are standing top edge leaning in, then change this rubber mount, similar to a trans mount or engine mount. bolts from the diff to the body of the car.

cheers. camber always a bugger on vp to VX with IRS.

ur right i can actually see the angle of the tires. new rubber mounts here we come

[spirto]

it's actually only one mount, bolts onto the rear of the diff, and up to the body just behind the petrol tank.
a quick check would be to jack the car up via the diff, if the diff moves up without the body moving up, then defineately a replacement job. but it's quite obvious when you remove this mount as it will be showing signs of the rubber split along the edge that it's glued to the metal mount bracket.

glad to help
