i just got a 96 x, and want to put some new rims and tires on it. i have a set of 18"s with 225/40/18 tires from the car i sold to get the x, and was thinking about buying some spacers and putting them on. i know the diameter of my 18" tires is less than stock, so the speedometer is gonna be off, but i was wonderring if there were gonna be any other problems, specifically safety problems. if u guys could give your input, that'd be great.
thanks.

nah other than bad gas mileage you should be fine
