I just purchased a 2004 G-35 Sedan and am looking for some advise on snow tires. Did anyone install snow tires last winter? Which ones did you purchase and were you happy with them. One of the local tire centers suggested that I install 16" tires with new rims. Can I use 16" tires on this car without screwing up the reading on the spedometer? I know it is a few months away but any information is appreciated.
