Wheels look great - tyres may be a little low profile? That and/or a small drop?

Not an S8? So maybe rides higher? Tyres look quite thin to me as well, what size are they?

(245/45R18 equates to 245/40R19)

i have the sport suspension already but want to upgrade it all.
Not sure any lower with all the speed bumps around so bigger tyres will have to do

I agree, tyres look like the wrong profile. The correct size would fill the arches more, what size are they?

they are 235/35/19

:eek:
Nearly 5% too small, your speedo will probably be illegal.

what size tyre will I need?

Hopefully someone will confirm, but correct size should be 245/40/19

Your current tyres have a sidewall of 3.2 inches, whereas the correct ones are 3.9 inches, almost 1.5 inches of sidewall missing.

Bigger tyres will help with the speed bumps too. ;)

Did those wheels and tyres come from an A4 or similar? And what width are the rims?

Have a look at the inside of your fuel flap for the normal/correct selection of tyres and post it here.
