Yeah, I drove my 46 around for several years with post 1953 wheels on the front with the 5.25" bore and a 4.75" pilot on the hub. They were on the truck when I got it. Got tires mounted on them and all. And I Never noticed it until I swapped wheels from the front to the back. Then I made some rings at work and pressed them in the wheels to pilot on the rear hub. Lucky I never had a problem! I FINALLY got retired, you guys probably noticed I've got more time on my hands.
