Maxxis VR-1 245/40/15
Just sitting over here wishing I had this tire on 10's and enough power to actually push it around. Hawt damn.
Fwiw that looks like the older bronze color (Gen3?) unless it's just the lighting. Gen4 is brighter.

Don't. Order another two 245/40/15's.
I have spoken.

I appreciate the helpful intentions from you guys, but I'm not running narrower in the front, I'm running wider in the rear. I'll run the widest, stickiest tire I can within other limitations. You can bet I'll bolt these on the front and inspect for interference, but I don't hold out much hope.

So wait. Given I can't run 245's on 10's in the front (may or may not be true, waiting to test fit), you guys think I should run narrower in the rear to have a square setup so it won't push?
Most forums proffer the silly myth of needing stagger so it doesn't kill you in a fire.
A car can be setup to work around a lot, and more grip is usually more grip. If you can add grip at one end and then change stiffness bias to shift some of that grip to the other end, it is usually a win.
Sure, it would be better to add grip at both ends if possible. The track width change that comes with it muddies the waters on judging how much grip was added, but if 245s in the rear shifts my balance so much that I need to compensate with a spring change, I'll be ecstatic.

FTFY
I'd be curious how a staggered setup would run. The Miata was designed to be a 50/50ish car, so the geometry is also complimented for that. However, tire cornering stiffness should be matched to the weight distribution, and for a given tire model, cornering stiffness is fairly linear in respect to width.
I think it'd be interesting to setup a Miata with 245 rear 225 front, match the weight distribution to the widths, then tune in the ride heights, camber, and toe and see how it compares to a well set up square car.
