best tire pressure gauge (tire pressure question)
 

hello everyone, i was wondering what tire pressure gauge everyone is using?

what is the best tire pressure gauge available out on the market now? one that possibly doesn't bleed air out too much when trying to engage the valve to get a measurement.

I want to keep the price reasonable but am not opposed to maybe spending around $100(buy once cry once).

also, i've always been told to measure and fill tires when cold or not driven for at least 2 hours.
Our cars being 35 psi all around, would it be ok to let's say fill up early morning when it's colder let's say around 40 degrees? then as the day progresses to the afternoon let's say the temperature increases to 60 or so, would the increase in PSI be ok due to the temperature increase?
I'd imagine car manufacturer's take the above into account and the recommended psi settings are for cold temperature measurements?

What are you using the car for? If it's just daily driving, you don't need anything fancy at all.

If you're serious into track use, you'll want to monitor hot temperatures RIGHT after coming off the track.

mostly daily driving, i have an older pencil analog type gauge but it is frustrating how much air bleeds out before I can make absolute contact to get a reading, i'm also not entirely sure how accurate it is considering it is an old gauge(5+ years)

occasional track/autocross but i intend on having a dedicated separate set of tires/wheels for those.

Unless air is bleeding out for a couple seconds, you're not losing significant pressure. I would just get an average dial analog gauge. I personally wouldn't want one that doesn't have a button to intentionally bleed off pressure, but that's just preference.

TireRack "The rule of thumb is for every 10° Fahrenheit change in air temperature, your tire's inflation pressure will change by about 1 psi (up with higher temperatures and down with lower)."

You see what happens when your tires get up to about 220F in the summer on track...

I like this one, not too expensive, measures in 0.1 increments, has a bleed valve, and doesn't let lots of air out when using it

Yeah, it tries to burn your hands as you bleed off pressure :D :D

This one has worked well for me (Accutire MS-4355GB Programmable Tire Gauge):

Quality piece but it will be a little bit less convenient than the one @Scenic Driver suggested, since you need to turn the top so that you can read the display when you push it in, and you have to unplug it after reading to use the bleeder, though you don't have to reset to re-read when you plug it back in.

What I use - very easy, precise, and accurate, and shine a light on the face for a few seconds and be able to take readings in total darkness... no batteries required either, have been using it for at least a decade... :

I love mine

Make sure to get a digital one. We all know how inaccurate analogue tire pressure gauges are.

I'd take a good quality fluid filled analog one over a digital one every day.
