20 inch wheels tyre question

[CHEF_GOLF]

Hi all
I have bought a set of Bentley wheels to go on my A8( it's being themed for a charity rally)
What size tyres will fit without fouling.
Currently running 245/45/18
Thanks

245/35 20’s are the same width and only 0.4% bigger diameter so this is the closest you can get.

I assume you’ve checked the ET is the same for the wheels?

The original ET is 48 the new ET is 42.
The rear tyres have good tread and are 275. Was planning to put 245 on the front. And increasing the front profile to 40 (rears35) to compensate for the rolling surface for the Quattro system.
Will the 275 be to big to fit without fouling but I’m not sure the 245 would fit the rear wheels without stretching them.

Which version A8?

I have a D4 S8 with 20" wheels and I'm running Goodyear Eagle F1 Asymmetric 3 (Audi AO) tyres on size 265/40.

If you have a D4 A8, I would think you can get away with xxx/40 on a 20" wheel.
