I have 2008 Mazda 3 i Touring 2.0L with no TPMS and 17" aluminum wheels. I'd like to put a set of steel wheels and winter tires on. 15" steel wheels fit an 2007 3i but are not offered for the 2008 3i on Tire Rack. Only 15" and 16" aluminums and 16' steels are. The 2007 3i lists the exact same 15" and 16" wheels on Tire Rack, plus 15" and 16" steel wheels are offered whereas the 2008 3i only offers 15" aluminum or 16" steel wheels. The calipers are shown as being the same part number on Rock Auto and the front rotors as shown with a 10.94" diameter / 5 bolt. I know there is a clearance issue with Mazda 3's with the 2.3L since the rotors are 11.81" diameter / 5 Bolt. The 15" steel wheels and tire end up being about $140 cheaper than 15" aluminum or 16" steels sets so it would be nice to go that route. Any help is appreciated.
