Ok, before my X1 I had a Ford Focus Mk1, and along with a new set of tyres the fitter decided to add nitrogen. I abhorred it - it made my car wholly unstable. It was much better after I bled them and refilled normal air. I'm not the only one who's found problems with nitrogen.

After that horrific experience there's no way I'm filling my X1 with nitrogen. To improve my ride quality I may fit regular tyres instead of the runflats when my motorplan ends.
