Can one of you pointy-head types break this down for me? Looking at 3 different sizes of rear tires.
What would be their characteristics or what would make one choice better than the other? Thanks! :D

The 315/30/18 would be horrible on the street in my opinion, not enough sidewall and you will go through aluminum rims regularly unless you go forged. The 295/35/18 has the highest sidewall at 4.1 inches and will give the best ride and rim protection, it's also the tallest tire and should help gas mileage due to highest "gearing" 772 revolutions per mile. My 2 cents says comfort and rim protection is worth losing 3/4 inch in width on 12" wide tires.
Thanks creek. I should have mentioned these would be strictly AX tires. Not for the street.
What does it matter? You'll get whichever is cheapest. ::Banana::
Comparison using a Tire Calculator
What is the stock size?
Wider gives more lateral traction vs. linear traction. Area of the contact patch remains the same for all sizes so I'm guessing the lateral traction is more desirable than linear for AX.
But then what affect would larger rear tires with more lateral grip have on the smaller front tires? Could you could change the entire balance of the car by just playing with the width of the rear tires??Quote:

::Whisp:: Sammm replaced his Miata with a Z06.Quote:

Several missing variables:
- Width of the rear wheels
- Width of the front wheels
- Expected front tire size
- 1st gear, 2nd gear, and rear end gearing (i.e., what will max speed be in 1st & 2nd with each tire size?)
While Mazda tends to set up it's rear-drive cars with uniform wheel and tire sizes, most other manufacturers do not. The stock Z06 is designed around staggered tire sizes, so Miata/Mazda specific experience isn't really going to apply.Quote:

I like 275 front, 315 rear. But since you are TCB the 295 are $68 cheaper. BTW DT will match the price.
Also important is setting the ride height. Dropping the front will make the rear very loose. I think you can drop the rear then balance the handling with the front height.
3 out of 4 ain't bad, but you missed the critical one. Back to school, young grasshopper. :wink:Quote:
