Different size tyres on a S8

S8_360 · 28-07-2010, 12:31 PM

Hi all, quick question can i puti 245/45/18 on the back and 235/45/18 on the front of my audi s8 d2.

Thanks

Why? IIRC the standard tyre size is 245/45-18 so fitting 235/45-18 would reduce front end grip and also make your speedo read 1.3% too fast.

Only if you don't like your centre differential.

Not a good idea fella.

The rolling diameter for front and rear should be equal to maintain the 4-wheel quattro stability.

I have seen different tyre sizes used, but they tend to be on larger rim sizes, but where people have used different width wheels too.

I'd advise against it
