Anyone running 255/50/16 here?

I'm rollingon 255/50/17... I don't ever remember seeing 16's that wide, maybe for trucks?

I was just thinking because when I compare the heights of 225/60/16 vs. 245/50/16 the 245/50/16 are a little over one inch shorter the the stockers. And when comparing the 255/50/16 they are only a half inch shorter and say the rim sizes are 7-9 in so I though they would work. so no one has though of this? :feedback

This is a tricky tire size. I did this for you using the miata.net tire calc, note the first one is stock that's why it says 0% change.

Tire Size Comparison

Specification  Sidewall  Radius  Diameter  Circumference  Revs/Mile  Difference
225/60-16         5.3in  13.3in    26.6in         83.7in        757        0.0%
255/45-16         4.5in  12.5in    25.0in         78.7in        806       -6.0%
255/50-16         5.0in  13.0in    26.0in         81.8in        775       -2.2%
255/55-16         5.5in  13.5in    27.0in         85.0in        746        1.6%

This all depends on a few things. Do you mind the extra sidewall? Do you put a lot of miles on your car? Do you mind it being slower off the line? Do you mind the speedo being off a bit? These are all choices you have to make.

I ran 245/50/16's for years on the Stock Octastar wheels. Loved them.

245/50-16 Nitto 555R Drag Radials here.

Would've went 255 no problems if they stocked 'em.
