Tyres / Wheels advice

Hi all,

I'm sure this will have been asked a lot of times but I can't quite suss out a couple of questions about tyres and wheels.

I was running 185/60 tyres all round on 14 inch wheels, but have shifted to 13 inch wheels with 185/55s at the front and 215/55s on 8 inch rims on the rear. I much prefer the the 13s but in the switch I have lost a lot of ride height... I haven't actually hit the sump yet but I do think I have touched down a couple of times! :) 

I've been looking at options for getting some ride height back, mainly around changing the shocks and springs and adding adjustable platforms, which I will probably still do. But I also wondered whether changing he tyres to 60 profile would actually get me a more useble height, obviously. It will, but is it going to be noticeably worthwhile! So a couple of questions...

1. How much extra clearance would 185/60s and potentially 205/60s actually give of 185/55s and 215/55s

2. Can 205/60s be fitted to 8 inch rims? I think its on the margins but there seems to be a lot of mixed opinion across different sites I have looked at.

Apologies if this has been asked a lot before but any advice is appreciated!

Difference in diameter on the fronts is 22m so 11mm gain in ride height using 185/60 based on the dimensions of the Toyo R888R v Avon ZZS / ZZR

What car and engine are your driving...?

205's will fit on 8" rims no problem

Thanks, that is great; 11mm will make a difference! I also thought that 205s would be OK...

The car is a standard S3 and is 1.4 Supersport so currently it is probably a tad over-tyred on the rear. I'm looking at R888r's as it is currently on ZZRs.

You are adding about 12mm of rake on the car with the new tyres compared with the old, which will affect handling somewhat. The adjustable platforms may still be a good way to go to re-adjust the rake. On the other hand increased oversteer due to rake increase may be offset by the rear tyre grip increase due to the wider tyre.

actually your are losing 4.5mm of rake based on moving from 215/55 - 185/55 Avons to 205/60 - 185/60 R888R

or were you comparing to 185/60/14..?
