As I have said before, I have 15x7 Chevy Rally wheels from a 1985 Chevy 4x4 on my 1948 Chevy 1/2 ton. I have changed the beauty rings to 1938 Buick/Oldsmobile "ribbed" Stainless steel rings. I used two pairs of rear center caps, and used after market 3" stickers to cover the 4x4 logo's. The tires are 225x70x15, and are adequate for the stock 4.10 gears and my 235 4spd. Though don't plan on doing much over 55 for any length of time, or you will wear out the torque tube bushings. I am planning on going to an open drive shaft and using the GMC 3.9 gears, and then do some brake upgrades, possibly even front disc brakes. Well, hope this helps you out, if you are going to 16" rims, use a 225x75x16 or a 235x85x16. The 225 will be about a 30 to 30 1/2 inch tall tire, will the 235x85 will be almost 33" tall. The 235x85 may cause some interference arounfd the front fenders, but will reduce the need for changing gears to make it streetable.
Good Luck, Garry
