Topic: tire pressure Posted: 28 May 2019 at 4:52pm |
+2 to OffGrid and Glue Guy. There are applications for Nitrogen inflated tires. If your plans don't include NASCAR and the Indy 500 with your TT, you'll probably be just fine. I do check my pressure regularly and check my lug nuts. I have D reated tires and I inflate to 65, per the sidewall.

+1. Nitrogen still permeates out so you have to check anyhow, even if you don't suspect a leak.

Warning - my math is not that reliable.

I get 3.74 grams/liter for Krypton at standard temperature and pressure so roughly around 20 grams in a tire at 65 psi, or maybe $6 a tire for a Krypton fill. Still way too expensive for me.

And that is at standard temperature and pressure. Add a factor of 3 for 55psi and you just spent $960 to fill your two tires. I think - Dissenters please feel free to post your homework -

It wasn't like that in the movies! They held it in their hands and it stopped Superman in his tracks. If it was in a movie, it must be true; like when I see it in the internet.

You'll need a better fridge than your Dometic which barely keeps food cool. The freezing point of Krypton is about -250F.
