dapat add din natin ang "digital type"
Dial type tire gauge din sa akin
Dial type is more accurate, since the pen type is just a slider inside the pen case while the dial has a fluid make readings more consistent.
Plus, the dial types with the release valves are useful for properly checking and changing tire pressures. Just add extra air and when it's cold, measure pressures and release air as necessary, even with the gauge in.
by those brands that are more of quality. those cheapo ones only lasted a few months before they get wacked.
What brand of dial type gauge can you guys recommend? I'm currently using one marked "Stetho-gauge" or something like that (it's about a year old already and still doing well). It's metal and it comes with a lockable plastic case.
Kung pang personal lang na gamit mo, pen type na lang. Tama sila, bili ka lang ng medyo mahal US or Japan made. Yung Japan made ko, ang tagal ko nang ginagamit, nakailang palit na ako ng sasakyan, ayos pa rin. Mas accurate pa nga kaysa sa mga gasolinahan. Pressure gauges sa mga gasolinahan, palagi sira. Ingatan mo lang. Wag mong ihahalo sa mga ibang tools.
Ngayon kung marami kang sasakyan, maganda yung dial type, depende rin sa brand. Ingatan mo rin para tumagal.
Be practical!
I'm using the pen type. I also check my tire pressure at the nearest gas station from my house every time I pump in gas.

I have a dial-type gauge that I use occasionally.
Mas madalas kasi akong mag-rely sa digital readout pag nagpapa-inflate ako sa Shell.![]()
I bought a dial-type na el cheapo pero nasira agad on my first attempt to use it :-)
Kaya ngayon digital na ang gamit ko--Digital gauge sa shell station :-). If a particular station doest have a digital air pump I don't buy gas from them
I use dial type since 1998. Haven't encountered any problem. Just preserve your gauges by releasing the air on the gauges after you takenote of the readings. Lately, I have read this article in the net:
[SIZE=3]Lies, damn lies, and tyre pressure gauges.[/SIZE]
Whilst on the subject of checking your tyres, you really ought to check the pressures once every couple of weeks too. Doing this does rather rely on you having, or having access to a working, accurate tyre pressure gauge. If you've got one of those free pencil-type gauges that car dealerships give away free, then I'll pop your bubble right now and tell you it's worth nothing. Same goes for the ones you find on a garage forecourt. Sure they'll fill the tyre with air, but they can be up to 20% out either way. Don't trust them. Only recently - since about 2003 - have I been able to trust digital gauges. Before that they were just junk - I had one which told me that the air in my garage was at 18psi with nothing attached to the valve. That's improved now and current-generation digital gauges are a lot more reliable. One thing to remember with digital gauges is to give them enough time to sample the pressure. If you pop it on and off, the reading will be low. Hold it on the valve cap for a few seconds and watch the display (if you can).
Generally speaking you should only trust a decent, branded pressure gauge that you can buy for a small outlay - $30 maybe - and keep it in your glove box. The best types are the ones housed in a brass casing with a radial display on the front and a pressure relief valve. I keep one in the car all the time and it's interesting to see how badly out the other cheaper or free ones are. My local garage forecourt has an in-line pressure gauge which over-reads by about 1.5psi. This means that if you rely on their gauge, your tyres are all 1.5psi short of their recommended inflation pressure. That's pretty bad. My local garage in England used to have one that under-read by nearly 6 psi, meaning everyone's tyres were rock-hard because they were 6psi over-inflated. I've yet to find one that matches my little calibrated gauge.
One reader pointed something else out to me. Realistically even a cheap pressure gauge is OK provided it is consistent. This is easy to check by taking three to five readings of the same tyre and confirming they are all the same, then confirming it reads (consistently) more for higher pressure and less for lower pressure.
One last note : if you're a motorcyclist, don't carry your pressure gauge in your pocket - if you come off, it will tear great chunks of flesh out of you as you careen down the road....
Just bought a digital type gauge from Handyman (guess they are also available in True Value), the Lotus LTG-095 Digital Tire Gauge. Comparing with the digital gauge in our Shell gas station, reading differs by about 1-1.5psi. Mine reads higher by that amount. Pero one time ko pa lang na-compare so it may be a difference in the temperature. Magkaibang araw kasi ako nag-measure. Anyway, mahirap din pala sa digital, nagiging OC ka masyado. Like one tire may read 30psi, while the opposite tire maybe at 29.5psi. Naku, suddenly you feel unbalanced ang car mo, na parang mas mababa sa kabilang side. Hehe. You want them to read perfectly equal, unlike sa analog na a difference of +/-2psi between tires doesn't really matter much. You really don't sweat much about it.
But it's a nice tool to have which doesn't cost much than a good quality analog equivalent. I have also checked for consistency and okay naman. If you get to seat the valve properly at once, you will get same readings. Kung medyo some air has escaped before it has seated, syempre you'll get lower readings na. Also, you have to really sample the air, not pop on and off, for it to read correctly. Minsan nga pag sobrang bilis nag-stay lang sa 0.0psi.
using pen type since my dad VW days... pamana sa akin, PCL brand made in england.... most of the digital gauge installed in gasoline station also are PCL brand.![]()
^ have you tried to compare the readings between your pen type gauge from the gas station digital gauge?
