Yep, you’re right there is some confusion regarding the Hellcat wheels. There is an addendum to the Hellcat instructions that the scale wheels will be 4.5” instead of 5”. When I received the scale wheels the packaging stated 5” but they were 4.5. I’m sure the downsize in diameter is due to the tight tolerances when the gear is retracted into the wheel well. HH and Tower need to change description on their website and packaging.
