I'm seeing this question being asked more and more so I'll make a sticky here that members can look up:

15-inch:
Width - 6.0 inches
Offset - 52.5mm
Tire size - P195/65R15 H-rated

16-inch:
Width - 6.5 inches
Offset - 52.5mm
Tire size - P205/55R16 H-rated

17-inch:
Width - 6.5 inches
Offset - 52.5mm
Tire size - P205/50R17 V-rated

Note: In N. American-spec, the Mazda3 2.3l engine is packaged with larger rotors, so any N. American-spec Mazda3 2.3l cannot go lower than 16-inch rims (brakes won't clear).

Spare tire
For 15-inch wheels: T115/70D15
For 16 or 17-inch wheels: T125/70D16

Edit: Bolt pattern is 5x114.3

17X7 with 42mm offset and 215/50/17 tires DO NOT rub at all with stock suspension. a 42mm offset actually pushes the wheels 16mm out further than stock, filling in some unwanted wheel gap.

this combo may rub with anything more than a 1" drop.
 
yes it does but barely...only notice it on mine if i am turning up a curb but very little
 
I know I posted this in the winter tire section, but I'll repost it here because it is a more appropriate thread. Here's the tire sizes and listings as far as what all the Mazda's take. (Tire list taken from the Mazda Tire Program book) This list applies to 2004 and 2005 models, and more than likely the 2006 models as well. Also keep in mind that the I model can be outfitted with the S model's tires (after upping the rim size) and the S model's tires can be outfitted with the S 5-door rims, as well. I don't know if you can downsize the rim size on the 5-door, but I would guess you can.

Mazda 3 I:
P195/65 R15:
89H, Toyo Proxes A18, 154610, (AS) (OEM)
89H, Michelin Tiger Paw Touring HR, 57917, (AS)
91Q, Bridgestone Blizzak WS-50, 062812, (W)

Mazda 3 S:
P205/55 R16:
89H, Toyo Proxes A05, 154620, (AS) (OEM)
89H, General/Continental Contitouringcontact CH95, 15463340000 (AS)
91H, General/Continental Contitouringcontact CH95, 03513940000 (AS)
89Q, Michelin Arctic Alpin, 58455 (W)
91H, Bridgestone Blizzak LM-22, 093262 (W)

Mazda 3 S 5 Door:

89H, Bridgestone Blizzak LM-22, 093327 (W)
 
Plus "Zero" sizing

Does anyone know for sure what a good plus zero size on 17" stock wheels would be?
e.g. 215/45x17"; 225/40x17" I'm not sure how far I could go with a 6.5" wheel width, and keep the circumference as close to stock as possible.

either of those should work.
'You sure about that? I can't seem to get a straight answer from most, but from 205 to 225 is over 3/4" difference (8.07" -8.86"= +.79".) It seems to me that the tire would bow out too much eliminating any positive affect on handling, braking, etc. What do you (or anyone here) think?

8.07" 8.86"
-6.5" -6.5"
------- -------
1.57" 2.36"

you have to remember that it will be even on both sides of the tire/wheel. so 3/4"= 3/8" on each side, which isn't much. if you're worried about it just put the OE size or the 215. 215/50 or 215/55 are discount tire's recommendation for plus 0. http://www.discounttiredirect.com/direct/assignTireVehicle.do?yr=2005&vid=008498 [/QUOTE]
Hmmm. Interesting way of looking at it. I'll give that a try... the 225/45 x 17's I mean.
I think if I can find some good ones in that size it would be a better choice to maintain stock circumference, and speedo accuracy. Thanks again CP!
Yeah, Discount recommended a one up size for my wife's Saturn and I should have known that would be trouble... especially the way SHE drives!! I think she's actually a member of the Andretti family....? :) We went from the stock 175/70's to a 185/70. Now her speedo is off and she complains that the car "doesn't feel right, slides in the rain. Spins tires." And we went from a really cheap crappy GY to a Kumho!

The problem with your wife's tires is that you went wider with the same aspect ratio. Assuming a 15" wheel, you should have gone with a 185/65 and it would have been almost perfect. Probably the reason the car doesn't feel right is because there's too much sidewall flex and the car is wallowing in corners. Not a good thing. If the tires aren't very old, I'd take them back to Discount and make them give you the right size.

Anyway, to answer your question about upsizing your 3, 225/45-17 is almost exactly the same diameter as stock but it's not recommended to mount a 225 tire on a 6.5" wheel. Depending on the sidewall stiffness of the tire you choose, you could definitely end up with some "balooning", resulting in premature tire wear.
If you check the manufacturer's web sites, most of them have specification charts that include a recommended wheel size.
For instance, the Kumho Ecsta ASX in 225/45-17 is recommended for use on a wheel between 7.0 and 8.5 inches wide. Half an inch may not seem like much but it can make a big difference if the tire isn't designed for it.

If you ever are curious about plus (or minus) sizing your tires, there's a great tire size calculator here: http://www.miata.net/garage/tirecalc.html
 
I wish my local Mazda dealer had been aware of this info before installing the wrong speed rating and size of winter tires on my Mazda3 (see my post "Dealer installed wrong tires - HELP!").

Apart from my speedometer and odometer being inaccurate, and the problem of snow/ice build-up in the "tighter" wheel well, are there any other things I should be concerned about?
 
so how about a 215/45 r17 with the eibach prokit, is this a pretty safe size, or should i just stick with a 205?
 
Any 215 tire is going to have a different diameter than stock. Stick with 205/50 or upsize to 225/45.
