You mean to suggest that at different tempratures all the gasses will behave the same way?? at 100 deg for eg the expansion of all gasses would be the same and hence would behave the same . At 30 psi and X temp a nitro filled tyre will behave diff from 30 psi of air at X temp. And the manufac recco's are for air and not nitro my dear. When i got my tyres nitro filled, i just noticed that tyres looked a tad under inflated and hence was worried that it might be bad for the tyres. |
