15" steelies won't fit on 2011 Mazda3 sport GT, require confirmation

[tubbyc]

I have a set of 15" winter tires on steelie for my 2005 Mazda 3 GS, after reading through the posts, it seem to me due to larger caliper, I won't be able to fit that set of winter tire on my 2011 Mazda 3 Sport GT right? thanks for the help

[mazdaskit]

i believe you need min 16" rims for the GT's due to the calipers

[S.F.W.]

Correct, you will need 16" rims and tires.

the callipers are bigger on the GT from the GS. 15" rims wont clear the callipers on the GT.

yes GS can run 15" GT 16

If you have a 2.0L you can put 15's and if you have the 2.3L or the 2.5L you need 16's
