S5 has different tire sizes than the S4

[JohnEnglish]

Several people have commented that the S4 now has narrower tires (245 on the B9 vs 255 on the B8/8.5). I noticed that the S5 coupe and S5 sportback both have 255 tires as standard and 265 if you get the optional 20" wheels.

i thought the B8/8.5 S4 Tires were always narrower than the B8/8.5 S5.. which is why the S5 rims fit perfectly without spacers on the S4

Tirerack.com lists them both as having 255/35 R19 tires and that's what my S4 has. I know a guy with a S5 and he has the same size.
