My study on Nitrogen in Tyres concludes

[kiwi]

All my tyres leak air over a month so they get topped up every week, so paying extra for nitrogen in my case would start to get rather expensive, i might need to top them up less frequently but they'd still need doing.

Well it did not cost me extra for the Nitrogen infact the tyres worked out cheaper than another tyre fitter qoute.
Next point was Firestone who are behind this do free refills for the life of the tyre, I topped up once. I already posted this info though in the first post.

Until you look into it Mulley it is easy to assume it will cost extra when it may not.

Lets put it this way I would NOT pay extra to have it put in.

I wouldn't worry about the Nitrogen thing Race tyres only need to last 50 miles on average and then they are scrap.

I was presuming NZ was different to the UK & i doubt anything on this shitty island is free.

More free stuff in the UK than what you think compared to these two shaken islands. For a start most our emergencies services (fire/ambo) here work for Free yet get no other reward.

Anyways another topic that but I did see in my searches a couple tyre suppliers in the UK that do include the gas free or should say inclusive.
