255/35-18 on a 2003 Q45? Any Issues?

[DuDro]

Greetings!

I am considering changing my OEM tires to a set of Pirelli PZero Nero, going from 245/45-18 to 255/35-18.

Are there any issues with this new tire size? Will they fit properly on the 18x7.5 wheels?

Any advice would be greatly appreciated...

Load index is far too small, as with OD..and no, they won't fit on a 7.5" wheel.soo..NO. Use the stock size.

Why change them to something inferior, just get the Pzero in the stock size....

I'll agree on the load rating and OD problem, as Chet has said.

But I'll stick my neck out and disagree with the "stay stock" recommendation. I have 255/40/18 Pirelli's on 2004 Q45 Premium wheels and they'll be a nice upgrade on your Q.
