R34Gtt Scubbing - One Wheel

[dex_911]

Hi Guys,

I have a question regarding rim / tyre size and why this is subbing only on one side of my car?

I have an R34 GTT on stock suspension and recently got some new rims and tyres fitted.

I’ll try provide the info as clear as I can in a list below:

· R34GTT Stock Suspension

· 18 x 9 rims

· I am unsure of offset at this stage (will confirm with the shop). I believe it’s different for the

front and rear. This is the info I have on the invoice: 18 x 9 ET22 and 18 x 9 ET15.

· The tires are 225/40 R18.

The Issue I have is only with the front left wheel:

· Moving straight / reversing straight = no issue

· Forward while turning right = no issue

· Forward while turning left =mild rubbing depending on speed and it’s near to full steering wheel lock. (I can go over road bumps and pot holes in a straight line with no rubbing).

· Reversing while turning left = massive rubbing / scubbing noise, sounds like the tire is hitting something plastic to me. It will continue to make this noise while reversing until I straighten the car out. This is particularly embarrassing when reversing out of car parking spaces and having this god awful scubbing noise the whole time.

· Reversing while turning right = no issue.

So this problem seems to arise when I’m turning the steering wheel to the left and it is only evident on my front left wheel.

Is this suspension related?

Is there something in the front left wheel arch that could cause this problem, as it’s not happening on the right side.

This was happening with my previous sets of rims also but they were 20” (Horrible things) – I thought they might have been the cause but since moving down in rim size, I am still experiencing this issue.

Any advice would be much appreciated.

Cheers!

Your offsets are 22 and 15.

You need to get down on your knees and look to see where it is rubbing. It will either be rubbing on;

• the outside edge of the tyre against the rear side of the wheel arch,
• the inside edge of the tyre against the engine bay rear part of the wheel arch (less likely),
• the inside edge of the tyre against the front side of the wheel arch.

It may be doing more than one of these seeing as it does it differently between going forward and backward. Going forward I would bet on the first of the above points. Going backward I would bet on the last of the abpve points. But I wouldn't bet a lot, because there are always other options!

If I were to point my finger at anything in particular, I would suggest that the caster rod bushes are probably rooted and allowing the wheel to move fore-aft in the wheel well as you apply loads (ie, drive forwards or backwards). But other buggered bushes can cause similar problems. The plastic liner could also just be loose in the wheel arch, sitting too close to the tyre.
