245 is the widest you can fit. You could probably go wider if you had a Grand Prix with the B4U body kit.
I had 15's on my Regal (205/70's) and went to a 235/50 on 17" wheels with no problems (no rubbing, no speedo problems.)

http://www.carbibles.com/tyre_bible.htmlscroll halfway down until you see "An ideal rim-width calculator" i don't know what the stock tire size is for the 15x6 crosslace wheel but i'm thinking a 225 would be pushing it. you probably have 205/70s. get some 16" or 17" wheels that are at least 7" wide. some 16x6.5 Cutty 5-spoke wheels would look good with some 235/55s and your speedometer would still be accurate. compare a tire sizes and their affect on speedometers here: http://www.miata.net/garage/tirecalc.html

yeah, i wouldnt go over 225. get some other wheels if you want wide tires. i think he was trying to say 245's would fit the car, not necessarily the wheels??

the car is going to be lowered so i think i will get 225 what does the second number mean in tires? It's the profile or sidewall height. It means that the sidewall is that percentage of the tire width tall. For instance, a 205/70 means the sidewall is 70% of tread width (205mm) tall. So, the sidewall is 205*.70 = 143.5mm tall. Remember, when calculating a tire diameter, you take the wheel size + 2 times the sidewall height. |

245 is the widest you can fit. a 245 is wayyyy too wide for a 6" wide wheel. yeah....they barely fit on a 7" wheel. |

What do you think of that? a 50 series isn't exactly "a little lower profile" than 70 series. with a 215/50, your overall wheel diameter would be almost 3" shorter, making the car look really funny and your speedo would read wayyy too fast...almost 11% too fast. if you don't have the money to do it right don't do it. |

I wouldn't get significantly wider/lower profile tires unless you lower it, otherwise it will look like ass with the huge wheel gap. I LOL'd at my friend's GP (245/45?/16) and brand new struts jacked it up.. looked funny.
