17s with 245/45/17 or 255/45/17 (I think) seem to be about golden for 94 Q...... Although, 16in seem to be about the best for Q..... 17s are a good choice though....
Be careful when buying rims..... If you get cheapo ones, they will bend very easily, as most arent designed for the Qs weight......
If you get them from
http://www.tirerack.com , be sure to use the links given here, as you get discounts..... Plus, all the rims they mention on their website will meet or exceed all OEM load capacaties and stuff like that......
I personally would recommend getting some infiniti take off rims..... I personally like the new Q rims or the G35 rims......
Just make sure whatever rims you decide to get, you have good tires to match it......!
