E.R. Wagner Pneumatic Plate Caster, Swivel, Soft Rubber on Steel Wheel, Ball Bearing, 200 lbs Capacity, 6" Wheel Dia, 2" Wheel Width, 7-1/2" Mount Height, 4-1/2" Plate Length, 4" Plate Width

Very nice pneumatic wheels. The casters attached easily with large bolts (not included) and the pneumatic tires are very durable. They swivel easily making it easy to push and move even a large heavy box. I would recommend the non-locking ones (these), the ones with the locks only lock the swivel not the tire itself making them kind of frustrating.

cant get an order right

Tire too soft, makes it hard to swivel.

Using them on a cart to haul firewood in from a gravel driveway. These roll over the bumps with ease and seem to be strong and well made.

This is a good quality caster. I use it to hold a 475 pound smoker that is used outdoors, and the pneumatic wheels make it much easier to move around vs. a caster with hard wheels.It gets a 4 instead of 5 stars because it does slowly lose air over time. Wagner warns you that periodic inflation is required, and that is true. About every 2 months I have to reinflate the tires to 50 PSI. If I don't, under lower pressure the tube shifts inside of the wheel, damaging the tube and/or the tire. You can move the tube back in position by taking the wheel apart, but it's time consuming.Some reviews of this (and the 4 inch plate version) state the brake doesn't lock the tire - but if the wheel is inflated to 50 PSI it does lock properly.

product is great. original order parts were mislabel took two tries to correct the issue.

These are great as long as the tires are fully inflated, but they have very small volume and don't stay inflated long. Then the tires migrate around the rims and damage the tube valve. The tubes are disappointingly low quality and split along the inner seams if you even slightly overinflate them, and 6x2 size inner tubes are not easy to find!
