I find it hard to comprehend "flatter cornering" from an extra 20% nitrogen in your tyres.

Its probably down to your wheel alignment if you had one...
Agreed.

Now bezza like everyone said it will not change your driving that significantly unless your tyres were previously under pressured.

Like someone said, nitrogen reacts to heat less then "air" and expands at a much smaller rate meaning it is good when your tyres are getting to very high temps (track day racing) and actually heating up the air enough to mess with your performance.
