How accurate is tire pressure monitor trd OR

With my 265-75/16 Toyos, I see 30/31psi cold in the dash and reads 34psi on my gauge https://www.intercompracing.com/4-ultra-deluxe-100psi-air-pressure-gauge-p-198.html. I live at 7000' which needs math to explain why this happens.

 

Mine are typically within a lb of my quality digital gauge.

 

Mine are spot on... well as near as I can measure with an analog gauge. I've got stock tires and like to run them on the high side. 35 hot and about 33 cold.

 

Why in the world would you take them out? Just don’t look at them.

 

They also report temperatures, and the spare also has a TPMS, but neither tech stream or dash displays that. But any SDR can easily pick up all the extra information.

 

That is really cool.

 

Mine are accurate to a couple of decent gauges I have.

I run 27 psi on the street.

 

I’m always down for a cold one

 

Mine are spot-on, compared to my $150 Moroso gauge, which has been tested and is accurate.

I've been running 30 front and 25 rear on the stock Goodyears, but I may go up a few lbs in the front.

And completely off topic, but what kind of top speed are folks seeing? These things obviously aren't race cars, but I was surprised... 112 is all mine's got.
