I have 215/45R-18 and they ok but I was thinking of swapping to a 225/50R-17 setup for slightly less harsh ride and at the same time a tad wider. I would imagine they should fit but not 100% sure.

Anybody running a 225/50R17 on their Mazda 3 GT?

I'll be running those next summer for my autocross tires, the 225/50R17. I'll be running 16's this winter, 205/55R16 and probably next summer for my daily tires 205/55R16 but possibly a 225/55R16. I think you should be fine running a 225/50R17 just ensure the rim is at least 17x7 if not 17x7.5 as @arathol suggested

This is a 205/50 on a 17x7.5" rim. Its stretched just enough to make the sidewalls less likely to roll in a hard corner. A 225 will be just about square on the same rim.

which makes a 215/50R17 the best compromise

Yeah except for the fact that decent 215/50-17 tires are few and far between.
This is true, so in conclusion for the OP, if its 205/50R17 your using then 17x7 rims, and if you want wider tires then 17x7.5 rims for 225/50R17's. Also, be very care to check the center bore size, our Mazda 3's are 67.1mm and from what I have seen isn't all that common. I already tried a test first of my old RSX rims and the center bore is just too small, not by much, but enough that it won't fit in the hub properly :( I was very sad.

Not necessarily. This depends on what you want from the tire. 205s fit fine on 7.5" rims, they just don't give you a square corner on the edge of the shoulder.



This is better from a performance stand point, doesn't really affect the way it rides either.
Don't forget that not all tires are the same width either. Some 205s are more like 215s.


225s on the same rim ride a bit softer because the sidewalls can flex more, but may or may not provide the same amount of grip as the 205 for that same reason depending on tire construction.

Many rims have bores that are larger then 67mm. Most aftermarket rims do, and spacer rings are available if you want to use them. Any rim that fits a 3rd generation Miata will fit a 3.

I'm running 225/50 r17 on 7.5 wheels but I have the I touring..

they fit perfect, the handling is night and day over the stock 16" and the ride quality does not feel harsh at all.
