...No hits in the Wheels and Tires Forum, so giving my fellow diesel compatriots a shot at this one...

So my old digital tire pressure gauge failed after many years of service.
I'm looking for a replacement - digital or needle.

My situation:
1 M-B, check all 5 tire pressures every other month or so. Prefer to keep gauge in glove box but okay in the trunk, too (if too large).

Yeah, I've looked on Amazon and Googled and every candidate seems to come along with hate comments along the lines of: Inaccurate, fell apart, drains battery fast, leaks a lot of air when trying to attach the gauge...

So, do you have (or know of) a quality-reliable gauge that you would recommend?

Thanks-

Have a look at companies that supply auto racers. Don't bother with a low end digital as digital does not always = accurate and you have to replace batteries.

Go with the standard analog dial on a hose. I made mine from a dial gauge and an air chuck. Here is an example of a basic $ 30 pre made one from a name racing company ( Longacre ) , it glows in the dark and has a air bleeder on the body. ( get the 0 - 60 psi model ) Longacre Basic 2" Tire Pressure Gauge 52004

I also have this $ 150 magnetic caster / camber gauge + a couple of brake caliper pistons ground parallel for adapters. Longacre Caster Camber Gauge 78260

Sweet!
That Longacre Basic 2" Tire Gauge looks good for my purposes - with air bleeder, too - score.
Very helpful information. Thank you!

How does the camber gauge work with non-ferrous wheels? Is there enough magnet to draw to the hub?

Magnet isn't strong enough to pull through the aluminum wheel. I haven't needed to make any adjustments on my MB. For a quick check I've used the register for the center cap realizing it is just a quick alignment sanity check.

For my oval track car the magnet slips over the grease cap and engages the steel hub. For my Formula Ford, a caliper piston parallel ground gets me over the grease cap in the front or rear hub nut and in contact with the flat surface of the aluminum wheel.

I've used different caliper pistons for other cars, at some point I need to modify some old alignment wheel adapters to accept a flat plate so I'm not having to rig up adapters.

Longacre sells threaded adapters for common race car spindles, something similar could be rigged up for a MB.

Accugage.

You want a bourdon tube type guage, its the most accurate type mechanical.

Be Very careful on ebay/amazon with the model being sold. Most venders use a file pic and not the actual guage being sold, and they are intentionally vague about the model, hoping to sell you a $20 guage for $50. There is a big difference between the M, the A and the cheapo model. The mid-model works well, only diff being where its built. Expect to spend $40-60 for the mid (A?).
