Does anyone know what tyres would I need if I went for a staggered fitment on my MK4. I.e standard width on front, 9.5J alloys on the rear?

Staggered ruins the handling.

Do you want stretch?

What you planning James?

Not neceserilly

But it will require a good geo setup and some good math to work out the best settings all round.

I always say, if a car didnt come with a staggered setup, then it shouldn't have a staggered setup.

You sound like my dad!

Grrr. So its not as simple as bolting some wheels on then.

The fronts would be 8.5, the rears 9.5. So OEM 225\40\18 on front ?.

I don't want silly stretch, but car has to be MOT legal, and Haldex safe.

[background=rgb(250, 250, 250)]245 is the smallest but will be ok, the optimum sizes are 255 or 265 with 275 being the max to fit to a 9.5 inch wide rim[/background]

In English mate

So any of those size in a 40 profile?,

 

[PaulW]

Always run the same profile front and back to keep the Haldex happy

255/40 will be no stretch and optimum for what your after. Sorry about the gobbledegook

i run 8.5 front and 9.5 rear on 225-40-18

you will get a little stretch on the rear.
Ive had no issues with the staggered fitment.
My car handles like its on rails and i drive it hard every single day.

If the rolling radius is the same all round, you shouldn't have any issues. Keep an eye on the angle of the drive shafts if you are going lower and wider as there may be a risk of putting more stress on them than is needed.

You will notice a problem straight away as you will literally hear the haldex growling at you

But, if the RR is the same all round (means good math on the tyres calculation etc) and a good geo setup id say you will be fine.

For me, personally, I dont see the point in it - the car puts most the power to the front wheels, so its not even as if you are on the limits of rear end grip anyway.

If you are going for the wheels I think you are, why not try and get them all in the 8.5 width?

 

[JamesBaby]

I was thinking if doing this, but without the crazy drop of course:

 

[PaulW]

What is important is for the rolling radius between the front and the back to be as close to one another.

The same profile on a wider tyre means a bigger sidewall hence a bigger rolling radius

e.g - 225/40 has a sidewall of 90mm whereas 275/40 has a sidewall of 110mm

Those pics dont count in this case as the rear wheels aren't powered

Unless thats just for inspiration

Ha, uhoh! He's gonna do it

Use something like http://www.willtheyfit.com/ and you can work out the Rolling Radius
