I got my 2015 Mazda 3 iSport about a month ago and love it so far. It is taking over as my DD because I need something that will actually WORK.
My other car is a 2011 Hyundai Genesis Coupe with more mods than I care to count. 392whp and 320 wtq on 21#s of boost. Pretty good for a 2.0L, but I also blew the motor in september during an auto cross...
Anyway, I have the the iSport with a manual and I know the wheels are 205/60/16, but I'm not sure if what the offsets are. I checked the wheel info page, but there wasn't any ETs for the 16s. I have a set of snow tires on rims that I want to use for the winter. They are 225/45/18 and 245/40/18 on 18x9 rims. I need to check the offsets, but any idea if they would fit?
