<span style=" font-size:10pt;font-family:sans-serif">There is a very easy
way that I calibrated all my TPG.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Go to a trusted
mechanic that you are friendly with. Ask him if he has a calibrated
gauge. (He most likely does.)</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Then, check all
your tires. Then, check your tires with your gauges. Compare
the readings.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I found that my
'accu-read' is spot on. My cheap HF ones are within a PSI. I
make a note like "reads +1PSI" on the gauge and I'm good to go.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I do this about
once every 3 or 4 years. I have noticed no read drift of the gauges.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Then, give your
buddy a 6-pack/gift card/ whatever token you have of appreciation.</span>
