Check the offset of those wheels before you buy them..better yet, try 'em on and drive around the block.

Mazdas have prett crazy offsets. For a 17 x 6.5 to fit, it's gotta have at least +40-45mm offset.

If they have 215/40's on there, your speedo will barely change because of the smaller tirewall.

 

215/40 is way smaller than stock size (this is a 3, not a protege .. i.e. when the speedo says 60, you're going 57).

195/65-15 is the stock size fyi

 

they do not have tires yet there for i cant drive them around the block yet but i did put one of them on today and it fit perfect good clearance of everything just dont want to get the wrong size tire
