Everyone will run different pressure depending on tyres, suspension, weight, roads you drive on etc. But you need to regularly check and find your sweet spot. In the last 4 utes I've had they were all different
At what rate does air (22%O2) permeate relative to N2 ? Is it a significant increase in pressure loss from, say, a 32in tyre on 18in rim would he loss of 1 psi occur over 4 months with N2 rather than 3 months with air ? All else being equal of course.
