place i do some work for we nitrogen fill everything.
customers like the sound of it, IT'S DRY , pressure varys less with tempriture, diffues through tyers and wheels slower ( virtualy insignificant unless there porus) much better for doing temp pressure logs with when doing fine tuneing. nitrogen cyls are still upto pressure on monday morning the compressor isn't
i've been know to fill tractor tyer with nitogen but for diffrent reasons
littel sh!tty compressor in van take's about a week to blow one up, littel 10ltr bottel of nitrogen woooosh job done and dont need to get genny out ether.
nitrogen is cheep, even in bottels 50 ltr cyl at 230 bar is about £10 and that fills a lot of tyers. in bulk tanks its a lot cheeper
