I have 305/30's and they fit perfectly on either the stock sport package wheel or my new 10.5" TSW Nurb's. 10.5" width is the same as the Nismo. I am also running 275/35's on the front with 9.5" wheels. I don't know why they told you that 305/30's wont fit. Me and several of my friends are using them with no issues.
