like i said up top im only going to run stagger if i have to i need wide in the back for drag racing i dont autocross the car but if i can fit the 225/45-16 toyo r1r tires then ill run them all around. plus alot of factory sports cars run stagger

The 215/45/16 is already large enough (diameter). That's exactly the tire I just picked up. But I dont see a reason to mix-and-match the compounds and widths. It is really worth the extra $175 for the rear tires?


I'd also like to see you fit the 225/45/16s up front, I know we couldn't fit a 225/50/15 on a lowered miata, and the 225/45/16 is the same diameter, 24". I'm worried about my 215/45s fitting...
I have 205/50/16s up front. they fit fine with my car lowered 2.5"

Most of these factory staggered setups are done to add understeer to the car because the mfgs. are afraid of people funking up the cars...makes it a it harder to induce oversteer....or because the engine is in the back/ the car has a lot of rear weight bias and needs it.

Or... btw... you can fit 245-35/16 tires on a NA miata....they should fit just fine on a NB.

I'm not liking the different tread patterns on front and back idea.

nah like these Hoosier A6 im kinda tempted to get em now anyway in narrower form 225-240 or so wide. Like i said understeer is your enemy and controlled oversteer via throttle is where the party is at.
