I used the 4.11, because it was available.

That is a good suggestion making the front and rear wheels identical. Originally I was thinking to put a wider tire on the rear. Based on the rear wheel fender well width, I can go only to about 8" max (allowing for additional section width), but I don't that size will work on the front. If I make all wheels the same I guess I would go with the 7" width rims max. I would need some rear wheel spacers to add an inch to the axle width on each side if I made all the rims the same.

I want to know what the original front end wheel offset distance is so that I can be sure to buy the correct rim offset for the front. I am assumming the offset is zero but I need to verify that.
