Tire Gauge 0-40PSI 3.5in GID Dual Bleed

The Longacre Tire Gauge 0-40PSI 3.5in GID Dual Bleed is a precision analog pressure instrument designed for serious automotive enthusiasts, mechanics, and race teams who demand accuracy during tire setup and maintenance. This glow-in-the-dark tire gauge excels in low-light shop environments and track-side situations where quick, reliable pressure readings are critical to vehicle performance and safety. Whether you're fine-tuning street car suspension geometry or managing competition tire temperatures, this instrument delivers the precision necessary for consistent results across repeated measurements.

The dual bleed valve design allows controlled pressure release, preventing overpressurization when adjusting tire pressures—an essential feature when working with high-performance or drag racing setups where 1–2 PSI variations impact handling and traction. The 0–40 PSI range covers both street and light-duty applications, while the large 3.5-inch diameter white face with 1/2 PSI increment markings ensures visibility and accuracy in direct sunlight or dim work bays. The silver metal case provides durability against workshop wear, and the glow-in-the-dark feature allows technicians to read pressures in engine bays, undercarriage work, or nighttime track sessions without external lighting.

Mechanics, performance shops, and automotive DIY builders benefit most from this gauge during suspension tuning, tire pressure optimization, and quality control checks. The dual bleed mechanism is particularly valuable for drag racers and autocross competitors adjusting compound-specific pressures before each session. This analog tool requires no batteries, making it a reliable backup to digital gauges and an essential addition to any professional or serious amateur shop toolkit for accurate tire maintenance and performance diagnostics.
