AC Delco 34646 Wheel Dollies any good?

[Mutt's37Buick]

Does anyone have experience with AC Delco 34646 Wheel Dollies?

Strength and easy to roll are my highest priorities.
They are rated 2000 lbs each so should be sturdy enough for my 4150 lb Roadmaster. They have 3" steel wheels (with no tire) and are supposed to be ball bearings but no grease zerks.
1) If you have tried these are they easy to roll around with a heavy vehicle on them?
2) Many of the more expensive wheel dollies have polymer wheels. Is this important to the wheels being easy to roll?
3) Will steel wheels mark up the floor? It is not painted.
Thanks

I don't see those being any better than the Harbor freight dollies.

I agree with Jim. My HF units Vehicle Dollies - 2 Piece, 1000 Lb. Capacity have 3.5" steel wheels and are rated for 1000# each. They have another model Vehicle Dollies - 2 Piece, 1500 Lb. Capacity rated 1500# each. You'll get a set of 4 for $100 or $120 depending on which you opt for, and can usually apply a coupon for any one item 20% off. I've used my steel wheel dolly's quite a bit on a smooth concrete floor - no marking of any kind. I'll bet if you go look at those AC Delco units you will find a Made in China listing on them, too.

I've heard this type is pretty good, compared to the other versions, but have no personal experience with them.

I've got a set that's the same design, same style wheels, etc. with a different name on them... They work ok for moving cars around, I can move one end at a time by myself, but it's a whole lot better with two people.... My rotisserie has 5" steel wheels, with a body hung on it I can pull or push either end around the shop with one hand. I've never seen a set of the type you referenced that is an easy, one man job to push a car around the shop on--all that mass rolling on what is such a small contact patch on the casters just isn't going to be a one man job with a 4,000+ pound car on them. More to do with rolling resistence then the design of the dollie or makeup of the casters.

Check out tireskate.com I have read very favorable reviews on these dollies and they look good to me. More expensive than harbor freight, but probably well worth it. They also have skate top that will bolt to their skates and allow the frame to be supported by the skate. For larger wheels, they have frame dollies that bolt to the frame. This stuff could be built but quality castors are expensive so they may be better deal. I plan on ordering some next week. Moved my '37 Roadmaster home yesterday, bought a couple of harbor freight furniture dollies yesterday for $11.99 each on sale. Glad I did because the rear of car had to be dragged sideways to get it out of garage it was stored in. Amazingly the car had not been driven since '52, but all four tires held air. The right front wheel was locked up, but I was able to drag car out of the garage with my truck. After it was moved to my new garage, I put a dolly under the locked wheel and pushed it in my garage with my truck. I'll let you know how the tireskates work when I receive them.
