Dual Fill Model 2 with 0-100 psig gauge. This is the most accurate way to fill your front tires to the same pressure. BRP tire pressure specs for the front tires is ± 0.25 psig and most gauges are ± 2.0 psig. This model has a 0-100 psig gauge so you must regulate the line air to less than 100 psig to avoid damage to the gauge. This model can be used to fill auto/truck tires as well as your Spyder tires.

Filling both tires at the same time gets the pressure in both tires equal. Unequal pressure in the front tires will cause pulling toward the tire with less pressure.
