You just addressed one of my concerns. The car rolled fine on the adaptors and wheels I welded up until I was ready for the rotisserie. Those wheels came from HF and worked well. I had thought about buying some pneumatic wheels from the same place, but hadn’t thought about leaving the original wheels on. I may try that. I was afraid I might have trouble getting a jack under the rotisserie frame if a tire went flat. Thanks for the suggestion and the photo. It’s a good one.
