Eastwood Rolling Tire and Wheel Storage Tree Dolly

I love (almost) everything about this! I purchased three of them - two for storing and moving my race wheels & tires, and one for my wife's winter snow wheel/tire setup. They went together easily, with every part fitting perfectly - even the very narrow tool for tightening the casters was appreciated! But all of the wheels and tires are apparently too wide, so I can't use the plastic disks on any of them - even the 2016 Explorer SUV wheels (8" wide on 255 tires) - and the center tube is too short for my race wheels (all 11" wide on 295 tires). Still, having them all on rollers makes moving and storage in the garage so much easier and the quality is very much appreciated, especially at this relatively low price point!
