I liked my old RPW gauge (which was stolen along with my car), it had an angled end piece that made it good for firm placement and better feel. apparently, rpw doesnt sell this style anymore. just the round end piece, seems to be better only for getting in tight areas where the valve stem is hard to reach on some wheels. I prefer the angled head. Pegasus doesnt have em listed on the website anymore either, except for a 0-15psi piece. I found a site, quickcar.net that still has em, but I'm wondering if anyone else knows of another site that still sells em.

this is what im talking about.

 

Oh fawk, I was going to buy one of those! I have been waiting to lose/brake my longacre one as an excuse to buy one of those.

I love the angled chuck and super fast bleed valve.

Please let me know if you find another source for them. I'm sure someone should be able to find what company was making them for RPW.

 

well, quickcar.net DOES have em, even a liquid filled option. just curious if theres any other place.

apparently one of their distributors sells quickcar.net stuff cheaper. http://www.randys-racemart.com/index.html

no only does the 45 degree end piece help, but the thicket boots at each end make it so much more comfortable to use.

My gauge has an angled head. I'm pretty sure I got it from racerpartswholesale.

 

I'll be in the market in a day or so...

I'm going to assume that the 60psi gauge is a bit less accurate than the 40psi. That said, have you ever found a need for anything over 40psi? If you did, was it at an autocross, or a track event?

I think the most I've ever known anybody to run any tires at was 42...

I doubt it and if they were, it wouldn't matter. Tires never heat up evenly or at the same rate.

Yes, on occasion.

Autocross.

I have seen and done a lot more then 42 (not that I would recommend it).

 

Tyson,

Can't help you with the angled head, but I found a gauge that looks very similar to the one in you picture, at my local Pep Boys. Was packaged as a "4x4" tire gauge with orange rubber encasing it, and a very nice quick bleeder button. Wasn't very expensive at all, and I have been nothing but pleased with it.

But...it doesn't have the angled head.

 

Try solo performance specialties http://www.soloperformance.com they have the one you have pictured. I have one that goes up to 60 psi and really like it.

I know the owners (drives a CP car). decent prices, and reputable (bought most of my stuff from them).

Depends if you use street tires. I run STS and will run up to the high 30's and the low 40's if I have my all seasons on. It just depends.

I don't think the 60psi is less accurate overall. If I remember correctly you don't want to operate them at the extreams. For instance, you don't want to use the 40 psi at 38psi.

 

Look for a Moroso part number 89550

I never understand why everyone at the track is stuck on analog dial guages that they think are the true racer deal. Digital guages are much more accurate and much easier for the manufacturers to calibrate, and they maintain their calibration over time, and they are very consistent. I have 3 identical Accutire guages and one very small Blue Point (Snap On) one with a tire depth monitor a mechanic friend gave me. All the four guages read exactly the same to 0.5 lbs, and I have checked that a couple of times. I have compared them with an expensive digital calibrated guage the tire guys at the track had, and my readings were identical. Buy digital and forget dial guages.

 

So are there any digital gagues that are easy to look at while you bleed the air? I thouht that was really the point of the hose/dial units we use.

brand names? part #'s? links?

 

Longacre sells a digital tire gauge. They are so popular I can't keep them on the shelves!

Analog tire gauges are most accurate in their middle range, that is why the 60psi unit is the most popular. So if you are running tire pressures around 28-34; 60 psi is the best. For drag cars and quads the lower pressure gauges work the best. i.e. 15psi, 40psi.

 

Interestingly enough....I use a $3 NAPA pen type gauge. It also fits nicely in my door pocket. You would think it would be a POS, but always reads identical to friends' accutire gauges. If only it had a speed bleeder....

 

Here is a Longacre cheap one with bleeder, $36 list:

Here are the Accutire gauges sold under various names, prices and brands by Tirerack, amazon, etc.:

Here is an FAQ talking about the accuracy of tire guages

http://www.getagauge.com/faq.cfm

Also liquid filled guages are less accurate than regular guages, as the purpose of the liquid is to damp the movement of the needle in high vibration environments.

A 60 psi gauge of B grade is accurate to 2% of full scale in the middle or 1.2 psi and may be calibrated to +- 1psi at 30 psi reading if you are lucky, and is accurate to 3% or 1.8 psi when close to the ends of the range. However, there is no easy way of knowing if your guage has been properly calibrated or what standard it is made to. So two good gauges could be off by 2.4 psi for the same tire if one reads high while the other reads low. That means one could read 30 psi while the other reads about 32.5 psi. This has been my experience while comparing a few analog guages at the track. That is why I went digital.

Here is a listing of guage accuarcy to impress your friends at the track:

Accuracy
Gauges are available with accuracies from +/-3/2/3% to 0.1% of span (ASME grade B to grade 4A) Gauges with +/-3/2/3% of span accuracy offer a +/-2% of span accuracy over the middle third of the scale and +/-3% of span on the balance of the scale. Generally, bourdon tube gauges with better accuracies are larger and more expensive.

ASME B40.1

GRADE ACCURACY

4A +/-0.1% Full Scale

3A +/-0.25% Full Scale

2A +/-0.50% Full Scale

1A +/-0.105% Full Scale

A +/-2-1-2% +/-1% over middle of scale, +/-2% over first and last 1/4 of scale

B +/-3-2-3% +/-2% over middle of scale, +/-3% over first and last 1/4 of scale

C +/-4-3-4% +/-3% over middle of scale, +/-4% over first and last 1/4 of scale

 

has anyone tried the tire gauges that are sold through the nsx club of america? i remember seeing a post about them on here a long time ago, but i dont know if anyone ever bought one. also, i assume some fairly common company makes those just with a different face. any insight on who would make those for nsxca?
