Max width for tyres on 18" and 19" wheels
 

Hi Guys ,
i'm picking up a 2005 A4 S-Line Avant this weekend which has 18" wheels with 235/40/18 tyres , all 4 wheels are badly kerbed so i'm gonna pick up a new set of rims ,
my question is this i've seen some nice 18 x 8.5 wheels and the manufacturers (wolfrace) recommend 245/40/18 tyres , will these tyres be too wide ?

They also offer these wheels in 19's so if i went for those what tyre size would you guys recommend ?

Cheers
Dave
