I own a JMI Medium Wheeley Bar with the standard 2 3/8" wheels. I'm thinking of upgrading to the 5" wheels but I'd like to know how close the 5" wheels come to the center of the leveling screw when the wheel is turned at its closest point to the screw.

The reason I'm asking is because I'm also looking at replacing the little plastic tips on the end of the leveling screws with 2" pads like these:


and I want to make sure that the 5" wheel will not bump up against the 2" pad.
