Slime's dually RV tire gauge is a heavy duty tire gauge that shines on equipment like RVs and 4x4's that often have hard to reach valve stems. The tire pressure shows up on a gauge that's connected by an 8-inch hose, making for easy reach on most tires. It also features a bleeding valve that keeps you from having to measure the same tire multiple times. | Slime 10-160 PSI Dually RV Tire Gauge
