Longacre Pro Precision Tire Gauge

The Cobalt SS/SC Driver Side Front Tire

The day was heavily overcast and sitting stably at 60°F. The tread of the Cobalt's driver side front tire was 67.2°F, stone cold. The sidewall was 68°F. Longacre recommends taking the reading from the tread. Although I couldn't find an explanation on their website, my educated guess is that it's more accurate for gauging the temperature of a tire that's been run.

Now it's time for the first test.

The cheap parts store tire gauge read 30.75 PSI after pushing it onto the valve stem, struggling to get a solid seal, and waiting a few seconds for the needle to settle.

The Longacre Pro Precision Tire Gauge read 31.75 PSI. The needle also settled instantly and the chuck was easier to get on the valve stem accurately without losing air pressure.

As you can see in the photo, the gauge is big — it just fits in my hand and I have good-sized hands. Photo: Ryan King, 2019.
