This tire and wheel set includes four rear tires and two front tires for a big rig tractor or use them on a rat rod or hot rod (see my comment below about dually wheels)

The tires are wide, soft and have tread detail. The tire size, "455/55 R22.5", is shown in raised letters on the sidewall.

Includes:

• 6 Treaded tires
• 6 Chrome inner wheels
• 6 Chrome outer wheels
• 6 Brake drums
• 6 Center caps with retainers

The rear wheels are deep dish while the front wheels are not.

I haven't tried it yet, but the rear wheels could probably be assembled into two really wide dually wheel sets. It looks like it may require a round spacer (3/4" diameter) to glue the two wheels together or a reducing spacer in the outer wheel hole (like Plastruct 90106) and a longer axle..
