I have found it relatively painless to replace and tighten wheel when using one of Woody's long thread headless bolts to get it started. The trick is to set on the ground with your legs under the car and the wheel on you upper legs above the knees. Using your large legs muscles to adjust the rims hole to line up with the long bolt and then sliding the wheel in to place is easy enough and NO BACK PAIN. It is a dirty job, but not hard when in a setting position.
