You can't go wrong with JACO gauges. The one you have there is the JACo ElitePro Series. A good gauge, with an accuracy of +/- 1.5% accuracy. Sales for 22.95. My go to gauge is the JACO ElitePro Digital Tire Pressure Gauge - 100psi. It has an ASME grade of 2A all across it’s range, 15-100 PSI. A2 is one of the top three grades set by the ASME (American Society of Mechanical Engineers). JACO tests their gauges in their NIST and ANSI certified testing labs. To put it in perspective, .5% of 32 PSI is 0.16 PSI. That is less than two tenths of a percent. Good enough for me. Specially considering that it sales for 29.95. JACO makes both versions (yours and mine) in compact versions, with no hoses. Unlike cheap manufactures, which might test (if at all) a gauge out each batch or one out of every few hundred, JACO tests every single gauge they produce. No, I do not work for them or get paid to write this. I used to be an Aviation Technician and for me accuracy of my tools, including torque wrenches and any other precision measuring devices is a must. For those who care, here is a reference to the accuracy grades of the ASME B40.1 standards. Which are taken at the lower 1/4, middle 1/2, and upper 1/4 of the gauge’s working range. The gauge is suppose to be off by the same percentage all throughout it’s range. Versus varying like cheap gauges often can do. 4A - 0.1% 3A - .0.25% 2A - 0.5% 1A - 1% A - 2% B - 3% C - 4% D - 5% Anything more than 5% can’t get an ASME grade. Anything that is sold without an ASME grade rating is not good for me. Hell, anything less than a 2A is not good for me. Specially for my motorcycles. Unless in an emergency and don't have a choice or just want to get a ballpark figure, like while deflating tires on off roading vehicles to go off roading.
Digital tire pressure gauge is the way to go. Easiest to read and priced the same as analog ones. Search for DIYCO digital tire pressure gauge on Amazon.
I've recently discovered that the only 'pencil' tire gauges to avoid are those $1.99 ones next to the cash register at a drugstore. Milton and NAPA provide quite reliable and accurate stick gauges for $6-7.99. The biggest factor in satisfactory results from any type of tire pressure gage - from a $6 pencil, to a $20 dial with bleeder, to a $40 digital model with bleeder, is the operator themself. I reset all my tires to the recommended 32psi cold at the begining of June - they were all a couple PSI higher since April - with a pencil gauge. I then verified with JACO's digital gauge, and the tires all ranged from 31.8 to 32.2psi. So #1: Don't impulse buy the cheapest stick gauge at the grocery and #2: Use it carefully. Overinflate tires the night before, then bleed them down little by little with the nub on the back of the stick gauge valve head. The tick mark for your desired pressure should be just showing below the red or black inner marker inside the metal tube of the gauge. If you're really good, you can split the dot. IE, 33psi, the first two dots should be fully visible, and the third dot(33) - partially visible.
I've used my bike pump many times on my corolla's tires. Can take anywhere from 1 to 3 minutes depending on how flat your tire is and the struggle doesn't start until you're hitting 35-40psi. Luckily now I have my Makita 40v inflator
Hmm, I use a cheap tire gauge same it work fine. I have an analog one that holds the reading, it works fine too. I use a bicycle floor pump to add a few psi and that doesn't take long either (my compressor is in the basement and I don't have a garage).
"Tires are only like 30lbs, they're less than a bike tire" This is true, but it's not a very intelligent counter to "it takes you all day". It does in fact take a LOT of pumping with a bike pump to fill a car tire, but it works in a pinch. ;)
@@SgtThorne I started out with hand pump to fill car tyres after mending flats or changing off the rims, I used inner tubes then 'cause hand pumps don't have the air rush to seat tubeless tyres
