Found A 17" OEM Wheel Option!

Rumor has it the 6-speed manual is on it's way for the 2.5 liter engine, so I'm starting to plan for a newer Mazda 3s. But there isn't a 17" wheel option for the 3rd generation Mazda3, only 16" and 18". The 16" size has an almost non existent summer tire selection, and the 18" summer selection is still below average. And the diameter is too large for my tastes and driving needs.

But if I go with a smaller but wider 17x7.5" from the Mazda 6 base model, that would allow me to run awesome-for-the-street 245/45/17 Michelin Pilot Super Sports. Or some less expensive 215/50/17 tires. Here is a Mazda 6 base model with 17x7.5" alloys:





Tires in the pictures above are the larger Mazda 6 tires (225/55/17). From what I've found online, the 17" Mazda 6 wheels have the same bolt circle (5x114.3 mm), center bore (67.1 mm), and an offset of 50 mm. The 17" wheel also allows me to run a staggered tire setup if I choose. 245/45/17 in front and 225/50/17 or 215/50/17 in the back, and I'd test this setup in both the dry + wet.

Here's a Mazda 6 17x7.5" accessory wheel with the same dimensions as the 17" Mazda 6 base model. I think it's from the UK. Part number GHP9-V3-810:



Update - Found a 2014 Mazda3 with 2014 Mazda6 Sport 17x7.5" wheels and proper-sized tires (215/50/17):












Here is a 17x7" wheel from a 2008 Mazda Miata MX-5. Owner of the car listed the wheel specs as +55 offset and weight of 17 lbs!



And a variety of 17" Mazda accessory wheels from Mazdashop.ca:

If we're going there...

I want you to go nuts and rebarrel those 17's into a 17x9 +47 configuration. Run a 5mm spacer up front and 245/40/17. Lots of fun, you shall have.

I've got 17x7.5's on my car (TSW Nurenburgings), and run a 225/50/17 Conti DW. I wasn't aware I could go with the 235/45 on a 7.5 wheel, but when I need new tires I may go this route!!

I was thinking that 225/50/17 would be the perfect compromize between looks and practicality. it is also just slightly larger diameter than stock. How do you like them? Any rubbing or clearance issues? What offset di you use?

No, no issues whatsoever. Ofset is 45.

I really like the look and feel of 18s with a 225/45/18 tire, but because of the insane amount of potholes here in KCMO, the 225/50/17 really makes driving around the city smooth.

Finally found another 2014 Mz3 owner with 2014 Mz6 Sport 17" wheels. I could definitely live with it:

How heavy are they?

I just picked up some lightly used 17" Miata MX-5 wheels on Craigslist for less than $200. Assuming the 16" alloys are in the 18 lb range, that would make them at least a pound lighter. It's not my first choice of style, but they'll be more durable than cheap aftermarket since they're OEM, and everything bolts up without modification (e.g., no hub centric rings needed). I plan on throwing those on at the end of the week.

Why Mazda chose to ship these cars with 16"s instead of these OEM 17"s is beyond me.

Good find, OP. Nice way to upsize your wheels, get better tires and still look stock I guess.

I'm not sure, but I would like to know as well.

For the 1st generation Mz3, by going from the newer 17x6.5" snowflake wheels to the older style 16x6.5" 5-spoke, I shaved a massive ~6 lbs per wheel. That weight is also an inch closer to the center and makes my 3 a little quicker in anything that doesn't involve a perfect launch from standstill or topping out on the freeway. It also allowed me to test and stay with a staggered (wider up front) tire fitment, which I found was perfect for dialing down understeer without having to mess with my suspension or alignment. I would place that mod in the same range as getting a lighter flywheel. But I don't expect the 17x7.5" Mz6 Sport wheels to weigh massively less than the Mz3s 18x7" wheels. I like that the 17x7.5" Mazda 6 Sport wheels will also give me that staggered option (245/45/17 in the front and 225/50/17 or 215/50/17 in the back) to test with on the newer 2014/15 Mz3. And yes you brought up another good point - the OEM alloys are more rugged, don't require hubcentric rings, or different lug nuts. And they won't likely get stolen.

Because Moon Patrol.

I'm picky especially with aftermarket wheels. I wouldn't want to put on any old set unless they were lighter, stronger, higher quality, have a somewhat ideal offset, looked good for my personal tastes, etc. Then there's the whole issue of parking in well lit areas, installing an alarm with long range paging ability, but not molest my factory wiring, etc. Or just go with OEM :cheesy:

I've asked that 2014 Mz3 owner to send me more pics from the side. If he/she does, I'll post them here.

Finally edited the other pictures of the Mazda 3 with Mazda 6 wheels and uploaded them. Attaching them in this post and adding them to the original post.

17 x 7.5 wheels

I am considering the Enkei Fujin (50 offset) and the Konig Feather (45 offset). They both weigh about 17 lbs.

Does anyone think that the Enkei's aren't worth the extra $50 per wheel? Any opinions on whether the difference in offset is significant or noticeable?

Guess which 17" OEM wheel also weighs about 17 lbs? Miata wheels and they're 7" wide. The spoke design makes it seem like it's 18". Updating original post:




Looks really good!! I would much rather have those rims than the 18" rims from the GT.
Yeah they're a little too big and not that impressive for an 18" design, and the 215/45/18 tire selection is not so good compared to 215/50/17.

Has anyone tried 225/50/17's on 7" wheels? According to the calculators it is at the high end of OK.

I just installed 17x7.5 rims with a 40mm offset and 215/50/17 tires switching from the 16'' alloy's ....I am noticing ever so slight bumping when accelerating from a stop. Is this normal?? From the thinner tire's maybe?

I'm running the oem 17s off a 2004 mz3 hatch on my car. Currently have 205/50/17 tires on them right now. Also, why not just switch the oem tires from the 215/45/18 to 225/40/18s. That is what i did with my RX8 wheels and they worked fine. Alot of the rx8 guys did that as well because of the limited choices for tires with the stock size

Thanks - I am in dire need of wheel spacers, though.

You are going to have to describe this "bumping" a lot better.

Yeah I prob should have picked a better thread for this question, but I had my lugs replaced yesterday b/c the ones sent to me were rusty cheap and after the new ones were put on the little jerks during acceleration pretty much went away. I think it had something to do with either my original lugs or the way a tire was put on during the initial installation. Here's a visual for the forum, pardon the back drop :)
