Bottom of dolly was scratched a lot from casters in box.

We have a 24 foot pontoon with 40 hp motor. Put 4 casters underneath and moved easily with my husband and I on cement floor. I was worried about the nuts against the floats, so I put an old blanket underneath. So glad we bought these!

Dollies were easy to assemble. Using these on a 1970 Chevy C10 truck that weighs about 4400lbs. It took 3 of us to push it around on a smooth concrete floor

I ordered two sets of these tire skates to move a small Cub Loboy tractor around my garage. The end result is they work great and I recommend them. I don't have any issues changing direction, but keep in mind the tractor is substantially lighter than a car. I still think I'd easily be able to move a full-sized automobile though as long as it was on good concrete.When the boxes arrived one arrived pretty beat up, but all parts and pieces were there so no harm no foul. The second box arrived a day later. It was in good condition, but one of the locking wheels was missing. I contacted the seller through Amazon's communication channel and I'm happy to say they were very responsive with their communication. They immediately shipped the missing wheel, so besides a small delay, I was able to assemble and use the skates right away. I'd definitely buy these again.

I was very afraid that I would not be able to move this 71 Chevy nova around the shop without two people. But the skates work great I can push the car around by myself. This car still has the motor and everything in it so it's pretty damn heavy.
