Different tyre width
« on: July 23, 2009, 04:04:56 pm »
Anyone tried putting say 235 rubber upfront and 225 rubber on the rear? That is supposed to reduce understeer.

I need to change my front tyres, and I am thinking Michelin Pilot Sport. At the same time I'm buying OZ Racing Alleggerita alloys in 8x18. So I thought, maybe put 235 rubber upfront and leave 225 rubber on the rear.
Is that stupid?

Quite an extreme way of doing it, its not just the width but the overall rolling radius that changes, so I wouldnt say it was a good idea myself.. Sure you would probably get away with it but its not a nice way of curing understeer

Running different tyre widths will produce different rolling circumferences as the sidewalls will be different. I'm not 100% certain, but I think it has given issues in the past (read some posts on "another" :wink: forum) with traction control/ESP cutting in due to these differences. :smiley:

Thanks guys!
It'll be 225/40 R18 Michelin PS2 then!

All I need to do is figure out what the damn abbreviations mean, that the site that I order tyres from puts after tyre names, like:
Michelin Pilot SPORT PS2
225/40 ZR18 92Y EL mit Felgenschutzleiste, M0, RR *

WHat is M0, RR, N2, N3, RRBL...  :stupid:

The tyre markings maybe different from country to country, but for the main the only ones you need to concern yourself with are in the link below....

You will also need tyres with extra load for the GTI :smiley:

I assume EL means XL
92 means 630kg load on tyre

I guess that is OK?
