I'm wondering if anyone has ever tried this, but I have a set of P225-75R15 studded snow tires, and am interested to see if I can get them to mount on my '00 GM, that takes P225-60R16" tires. I have found this neat website called "miata.net" tire size calculator, and you can put in the 'stock' tire, then put in the 'new' tire, and it will show the difference in diameter, plus what your speedometer will show with the difference.
I have punched in both tire sizes, and ironically, the 15" tire is bigger in diameter-a whole 1.7" taller! That will slow the speedometer down by 3.7 mph, so if the speedo says 60, I'll actually be doing 63.7. This is a really neat site!
Anyway, the two questions I have, is can I get a 15" rim, that will fit the bolt pattern of the '00 GM, and my snow tires will then fit on the car (and clear the rotors/calipers, etc.), and also what kind of OBDII connector tool would I need to re calibrate the speedo? If it will cost an arm, and a leg, then I'll just live with it. I'll only be using the snows when the weather is really nasty, as the wife is driving a long distance to work right now. These snow tires, along with the traction control, and ABS, should make this car almost unstoppable! At the very least, I hope it will keep the wife out of the ditch/median of the tollway!
Thanks,
John
