or else you will screw up your speedometer. I'm pretty sure that the speedometer, is run from a computer which take the wheel RPM and set diameter to calculate the speed of the car. So if you increase overall tire diameter you will be going faster than you think you are. Also if you go bigger with tire diameter you will most likely rub the inner hub of the car. anytime you hit a bump you it'll be like taking a circular saw to the inside of you car. Just some things to keep in mind
