Check my maths please.
So I am now on 4th crack 225M wheel and I am looking to go aftermarket now.
I'm thinking 20" for the sake of style and an additional reminder to slow down. I believe my current standard set up is as follows: Front: 19x8 ET37 with 225/35 R19 tyres Rear: 19x9 ET39 with 255/30 R19 tyres The wheels I am looking at are: Front: 20x9 ET35 Rear: 20x10.5 ET38 I am guessing my tyres should be: Front: 250/30 (or 25) R20 Rear: 275/30 (or 25) R20. Other than considering 20 inch wheels, am I doing anything wrong? Will it fit offeres up a diagram for this: http://www.willtheyfit.com/index.php...et2=38#content |

I've no idea whether these will physically fit without fouling anything but the 25 profile is closer to your existing setup as far as rolling radius goes & won't lift you up on stilts

Compared to your existing wheel, this new wheel will have an inner rim which is 18.1mm closer to the suspension strut. The outer rim will poke out 20.1mm more than before. The rim does look quite close in the diagram |

235/35/20 265/30/20 If you go for wider rubber, you may get a bit of rubbing. It depends on if you are on standard suspension or aftermarket suspension / dropped car.

Well I am on standard Msport suspension so I don't know what that would mean but after much deliberation across the weekend, I have just ordered some 20" rims and I'll be looking to get tyres sizes recommended by Makkan. I'll post a pic once its set up.
