Wide Offset

[Younez]

I have added alloys that have a wide offset but are same size tyre as OEM. The car is lowered by 20mm and when doing high speeds it appears to be hitting the car when going over bad road. I did not have this problem with the same set up on OEM alloys.

Would a geo be able to fix this, to note it was already done when fitted.

OR

Should I stick the OEM alloys back on, my worry is the tyre may blow if hit too much at speed.

Thanks.

Can you explain a bit better what you mean by this?

Offset is the distance between the centre line of the wheel and the mounting face.


Change that, and you've got more wheel sitting on one side - if it's gone towards the centre of the car, then you're likely to hit suspension, and if it's gone the other way, you may very well have wheelarch hitting tyre.

As in when going high speed on poor quality tarmac, it is hitting I imagine the wheel arch as they sit slightly out on the rear.

Other than the offset, as discussed above, if the wheel is wider than OEM, it will also have an impact on clearance to the strut and wheelarch.

You really need to provide more information on what the width and offset of the wheels are.

same size just much wider offset

I think will stick oem's back as don't want to risk it for looks

thanks

The wheel must clear the bodywork and suspension through the whole range of suspension and steering positions. If you don't know whether you have clearance, it is easy enough to check it or get it checked. Having the tyre hit the suspension or bodywork is potentially very dangerous so this check is quite important..

Let's see a pic.

the rears are the issue

No great surprise you're getting contact on a bit of suspension travel.

Are the arches rolled? If not that might give clearance.
