Alright Gents, so first, I got the 19" Mazda 6 Gunmetal rims today -- woot woot -- they'll be going on in the Spring of 2017 after the New England winter.

So I'm stuck between two options for rubber and was wondering if you guys could weigh in here.

235/35R19:
- These are the closest to the stock diameter (which is SUPER important to me)
- When my speedo says 70mph, the car is actually traveling 69.61mph -- certainly close enough for government work

- The problem: 235/35R19 is rated for an 8" rim at minimum. The M6 Wheels are 19x7.5.
- I've seen plenty of people stick it on a 7.5" rim, and I'm not what you'd consider a spirited driver

- What's your guy's input on that? Go for it, or way too risky? The tires are going to be Conti DWS 06. It's a high quality tire with a superior sidewall and ride quality. Am I putting too much thought into this? Or is the concern real?

My other option is 225/35R19 - which is rated for a 7.5" rim - but this will cause the speedo to be off by about 1mph. Which I get it, not a big deal -- it's just an OCD thing to me...

And I suppose my other option is 225/40R19, but then my Speedo is off in the other direction

Love to hear your guys' thoughts. Thanks.

Suggest, though based on what you posted you may well have done so already, that you visit your specific tire options on TireRack.com and they will give not just the revolutions per minute on the tires you are considering (and you can compare those to stock and other), and also provides the tire rim width rec for each tire. And if you want more info, as I sometimes do, I ask to speak to their XXX car brand specialist. Amazing how tire/wheel smart they are.

Best of luck, though clearly you have been doing lots of good research already.

Many are running 225/40s, good sir. You won't regret that bit of added sidewall. You won't feel any ride compromise vs stock.:)
Oh, 5mm hubcentric spacers will make this set up even sicker.:)
Can't wait!!!!!

You know. I've been wondering about the 5mm spacers. Do you have any pics that show the
results? That would be most helpful in making my decision!! Thanks @minsanity

Gosh M, that's still pretty close w/o spacers! Love the way these 3s look with the 19s and a mild drop! So sexy. I'm going to order the 5mm spacers and try and before and after. The State of Massachusetts is a little weird about stuff like spacers and I have to have the car inspected annually.

I'm going to drive myself insane through the winter -- not sure I'll be able to make it lol.

And I'm sold on the 225/40. Conti DWS rubber on the way!

I wish I could carry the wait for you, Chazzy sir.,:)
You're moving from a superb OEM+ setup to the ultimate. Grats, sir!!!!
