Hello, I was wondering if any of you guys knew what the offset has to be in order to put 225/50 tires on a 73 3.0cs. And, can you put 225s on the back and 205s on the front...if the front wheels are 7 by 16 and the backs are 8 by 16. The wheels set I want to get consist of two 7 and two 8 inch wheels. What size tires should I get and what should the offset be for these wheels? Thanks. - -MAX 3.0cs
