This is the original Heavy Duty Auto Dolly!.  The 12" width is perfect for a wide range of modern passenger and truck tires.  Like all of the casters on the Auto Dollies, the heavy duty caster contains a mar-resistant polyolefin wheel that also features a crown profile.  The crown profile wheel means less rolling resistance in contact with the ground.  The wheel profile also helps to pinch small debris out of the path, rather than coming to a screeching halt.

Like the entire line of The Auto Dolly, the 12" with Heavy Duty Casters is made of super strong 1/4" steel, not flimsy stamped steel.  With the Heavy Duty caters, this means that an individual Dolly has a weight capacity of a whopping 2500 lbs (5000 lbs per pair, 10,000 lbs per set of 4).

You can extend the usefulness of the 12" Auto Dolly sets through exclusive auto dolly attachments you can find in the related items below.

  • 1/4" Steel
  • 2500 lb capacity (single dolly), 5000 lb capacity (pair), 10,000 lb capacity (set of 4)

Don't let the Auto Dolly name fool you. Auto Dolly's may also be used for your truck or sport utility vehicle also. The heavy duty Auto Dolly will support your truck or SUV without any problems.  Knowing your truck or SUV's gross vehicle weight (GVW) is always a good idea. You can find this information usually on a sticker inside the door panel of your vehicle or by contacting your local dealer.
