tire sidewall

[Zsolt]

Hi Pedro,

Just one comment. 205 wide tires should be ok, for 7" rims. It is the
stock size on the 84-89 Porsche 911 Carrera. You can also use 225 on
that rim, (although it is not recommended) a lot of Porsche guys do so.
IMO, you should go 205 mm.

Also, 225 wide tires are stock on the 2000-2003 S4 Avus style wheels
that are 17x7.5.

Cheers,
 Zsolt
