I had a Grant wood tri-spoke wheel on my car. I loved it except for two things: 1: wood and aluminum get CRAZY hot in the sun. 2: The horn button popped off and locked the horn on, then I remembered that you shouldn't grab a wire on a closed circuit while driving on the interstate (or ever, really).
Also, I didn't have power steering and never had a problem muscling the car around. Of course, I have a Slant car. The wheel wasn't much smaller than the original. I'd be putting it back on if I hadn't found a really nice '65 Barracuda wheel to replace it. I love the Valiant logo horn buttons on those wheels.
