Nitrogen in Tyres? Do you use it?

[Doug_MPS6]

Among all the mooted benefits listed above, the principle reason some folks go for N2 is that being a slightly larger molecule than O2, it tends to bleed less rapidly through modern rubber/synthetic compounds used in tyre construction, and hence reduces (but not eliminate) pressure loss.

Also, see http://www.getnitrogen.org/pdf/graham.pdf on permeation of gases through tyre rubber

I doubt the average punter is going to be travelling fast enough in this daft speed-restriction obsessed country to make some of the other benefits, like lower coefficient of expansion, matter a damn.

Cheaper to visit the servo every weekend, I reckon, for my style of motoring at any rate.
