Pressure gauges

[Gary18]

Hi All,
Been looking for a good accurate pressure gauge that can be used for the car tyres as wel as bikes (motor & pedal variety) and came across this one from Moroso http://www.moroso.com/catalog/categorydisplay.asp?catcode=27107
Does anyone have an opinion of these or recommendations for an alternative bearing in mind I will have to import to the UK since there are no distributors over here?
I have looked at UK stocks but am struggling to find a nice 4" dial with clear graduations so the pressures can be easily checked & set. I'm not too keen on a digital gauge as I think the analogue ones are better and easier to have recalibrated as & when required.

Thanks,
Gary

Dumb question, do you measure in psi, kpa or mpa?

Wika 3" or 4" mirrored 0 - 60 psi gauge on a hose with bleeder for fine adjustments. I bought a 1% 1% 1% oil filled WIKA and it is wonderful. When you buy a gauge the % error is at center scale. This means that a 2% 0-60 gauge is within 2% at 30 psi. Most gauges are 3% to 5%. If you get a 5% gauge it will be off up to 1.5 psi at center scale. Some gauges will list like 3/2/3 which is 3% at each end and 2% in the center.

Moroso sells decent equipment. Lots of those around - you can also look at Speedway Motors web site for a selection of dial pressure gages. Yes, most gages are 3~5%. You'll pay extra for more accuracy, if you suppose you need it. Your pressure can vary that much depending on the weather. For our drag tires here, I use gages that read max under 30 psi. Usually the gages in the tow cars disagree by about 1 lb. This would be significant if I was running Top Dragster at 190 MPH and tuning between 5 1/2 and 6 1/2 lbs in a 33" tire. I'm not, so it's not a big deal

the 1st (and best) dial guage i bought was an accugage.

had it since the late 70's

FWIW

i was more concerned with repeatability of the guage, once i figured out where my tire pressures should be for track conditions, all cared about was being able to adjust from there.

for example, my guage reads 6psi, during heat races, and as the sun went down, the track got watered, hard and dry down low, nice "tacky" cushion on top, ect ect.

i knew i had to drop or raise my pressuse 1 or 1 1/2 lb (from where i started at) and still be able to set "stagger" between the rear tires.
one ATC liked a 2 lb stagger, the other looked up better with a 4-5 lb stagger.

it was always "fun" getting the front wheel up at 60-70mph with that much of a stagger

crewchief lives the name - good data.
