    Tire Size Calculator

    This will help all who want bigger rims and/or tires for their car. Get your speed right, so you don't get a ticket!

    For example, 17'' rims, nominal tire size is 205/50 R17. It will have you going 60.2mph when you're speedometer says 60mph.

      Well, now there's a link for everyone else to use as well if they didn't already know about it. I've been using it for the past 2 years, and just never thought to post it till now.

            lol, my switch from 205/55 R16 to 205/50 R16 threw my speedometer off by 3.2%. 60mph is actually 58.1 mph.

                  Yeah, I too have been using that Miata tire calculator for years as well. Jon turned me to a new one at a place called Big Custom wheels. They sell some gangsta ass rims and some monster brake kits for the hoopties BUT they have a great tire/wheel calculator for wheel offset and tire size. You can also compare two at one time to see the difference.

                  It is setup nicely, check it out.
