<VV> Lakewood Question: Max Rear Tire and Wheel Size

[angrycorvair at aol.com]

Looking for info from wagon owners:   how much wheel and tire will package within an unmodified Lakewood rear wheel well?   i want to squeeze as wide a tire under the car as i can for autocrossing.   i'll be buying wheels specifically for the autocross tires, so when you tell me tire size please also tell me the dimensions of the wheels you're using.
 
thanks for the help.
