Re: Highest cold Inflation pressure?

Tue Oct 30, 2018 7:44 pm

I only fill my tires when cold (car has sat overnight), but I do not bother with a gauge. I find it much easier to use the built-in pressure indicator. I use a 12v compressor that connects to the battery terminals. ... +00088+88P
I turn the car on, when filling the tires, so the battery doesn't drain too much. When it gets up to the recommended pressure, the car horn honks once. When it hits what the system considers the maximum acceptable pressure, the horn honks three times. I then turn off the compressor and move to the next tire. The gauge on the air compressor shows 42psi when I get the three honks. The ride is a little rough, but seems to be okay with the new Ecopias I put on it a couple months ago.

FWIW, I like this type of gauge. It has a little thumb button that lets you easily bleed air after overshooting so you can land right on the line. This helps get all tires exactly the same and I find it useful in that I get an accurate measure of how much the PSI has changed per tire since the last check. ... 0-psi.html
I noticed you're still working with polymers.

I have a Campbell-Hausfeld portable cordless inflator with a built-in 12 volt SLA battery and a 12 volt accessory port. The gauge is accurate enough that I can watch it as I inflate, overshoot by 1psi, then open and remove the clamp-type valve before I shut it off, and get the pressure I want without the extra step of using a separate gauge. It's held up well over two years or so, even surviving a blast from the garden hose. (I dried it out with a fan before using it again.)
