I have a 97 Chevy S10 and 1978 Malibu Wagon.

On the S10 - it's a short bed, reg. cab. - I am wanting to know how wide of a wheel I can go before anything rubs the frame WITHOUT tubbing.

On the Malibu Wagon - How wide of a wheel can I stick in the back of it?? I am old-fashioned, and love the rear to be higher with some big tires sticking out.
