[triplerc]

Any time you go lower profile, without getting a bigger rim, your gonna throw your speedo out..

Go to
http://www.miata.net/garage/tirecalc.html

And play around a bit, it'l tell you what tires you can use and how much your speedo will be out

Its not going to be out by that much is you just step the profile down a little bit.

thats a pretty sweet site, if its accurate...

[DaMoNe6969]

I compared it to some manuals at a tire shop, if it isnt accurate itd be pretty damn close

there really is only 2 choices for a lower profile you are going to get when keeping the 16" rim unless you goto a skinnier tire. here are your 4 tire choices without going to a skinnier tire.

here are your choices:
245/50-16 STOCK, 122.5mm tall sidewall
245/45-16 110.25mm tall sidewall
255/50-16 127.5mm tall sidewall
265/45-16 119.25mm sidewall
265/50-16 132.5mm tall sidewall
