Longacre Pro Precision Tire Gauge
The Cobalt SS/SC Passenger Side Rear Tire
The test on the Cobalt's passenger side rear tire was nearly identical to that of the passenger front tire. The reading for the parts store gauge was 31 PSI, the Longacre Pro Precision Tire Gauge showed 31.25 PSI.
The only difference for this test was the tire tread temperature which read 65.7°F — 1°F lower than the passenger front and 1.5°F cooler than the driver side front.
With only a slight temperature difference well below the 5°F threshold, I kept this tire's pressure the same as the others at 32 PSI — and just as it did adjusting the previous two tires, the Longacre Gauge performed flawlessly.
I can get used to this. Photo: Ryan King, 2019.
