20 x 6.00 truck balloon tires are used with the dual wheel equipment on the truck. The same size tires are used on both front and rear wheels; the wheels are interchangeable. The recommended tire pressure for 20 x 6.00 tires is 45 pounds for both front and rear wheels.
When dual wheel equipment is used, it will only be necessary to carry one spare.
When single equipment is used 20 x 6.00 tires are mounted on the front wheels and 32 x 6 tires are mounted on the rear wheels.
We suggest that only a 32 x 6 tire be carried for a spare, as when tire trouble occurs it is usually the rear tire. Should trouble be experienced with the 20 x 6.00 front tire, the 32 x 6 spare can be temporarily used in its place while the 20 x 6.00 tire is being repaired.
The recommended tire pressure for 32 x 6 tires is 90 pounds.
