Upgrading alloys. What tyre size ?

[sha666y]

Hi. I've got a 2007 Audi A4 avant s-line special edition 170bhp. It's currently got the standard 18' alloys with 235 40zr18 95y tyres fitted. I've seen a set of 19' concaved alloys sized 19 x 8.5j et35. Just need to know the best tyre size for these new alloys to compensate for the larger wheels.

Welcome to VWAF :)

Is the car lowered?

If stock, 245 / 35 will fit and retain your rolling radius.

I've got a set of the same double-spoked wheels from mine. Not going to tip the garage upside down to check, but pretty sure they're ET42 so you'll have 7mm more poke before you fit wide tyres assuming the same width wheels (can't remember if they're 8 or 8.5). Worth checking on willtheyfit.com.

If I can interest you in a set of 5 matching wheels for winter on the other hand....;)
