S8 20" Final Edition correct tyre size (8.5J)?

Hi folks,

What's the correct tyre size to use on a D2 S8? I'm getting mixed opinions suggesting 265/35 and 275/35.

Cheers

EKTA suggests the tyre size as 255/35x20 RMI

For the 8.5x20 A8 wheel.

Thanks.

I've just done a few rolling circumference comparisons on those tyre conversion websites and other 'matches' come out as 275/30 and 285/30. Would these run the risk of catching somewhere?

Some prices

255/35x20
Pimewell 97WXL 99.99 plus vat
Avon 97YXL 167.50 plus vat
Michelin 97YXL 235.00 plus vat

275/30x20
ACCELERA 97Y XL 99.99 plus vat
PIRELLI P0 NERO 97Y XL 149.99 plus vat

That's a mean price difference!

Thicker all the way

I have 285/30/20 D3 wheels on mine and don't rub.

On a 8.5" rim?

The D3's will be the 9J rim.

Amar, is yours on coilovers or standard setup? Would that make a difference to catching?

Mine is standard and yep 9.0'' alloy, and have 4x 285/30/20 Michelin PS2s all round.  There is a guy on the A8 Parts forum running 295 25 21 Khans on a 10'' rim I think...

Managed to source some 275/35 20s. Now I know the rolling circumference is about 2% off but worse still, the fronts are catching ever so slightly on the arms.

Next step - would 10mm spacers solve my problem whilst also filling the arches nicely or will I be messing the geometry up? The offset would effectively be ET35 with the spacers.
