nitrogen in tyres
 

been reading a few web sites recently about nitrogen and cant understand why we are not all using it in our tyres. there seems to be a lot of plus points and no bad points in using this. does anybody know any more info about nitrogen in tyres ?
had my tyres filled today at kwikfit for £5 but then only drove about a mile home so dont know yet if it feels better. the man at kwikfit said i will feel the difference.

have a look at this

Clever, but they still can't spell tyre :D
I can't tell the difference by the way, but then perhaps I was conned

The only 2 advantages of nitrogen that will effect most drivers are the molecules are larger so tyres need less topping up as it doesn't leek out so readily and it expands less when heated.

Downsides are cost and availability.

didnt you watch Jay Leno's video on the website that Darren linked to Mike???
Im sure there was more than 2 benefits, but that having said he didnt mention the price or ease of availablity :p

Is that the Jay Leno video sponsored by Nitrogen suppliers?

umm. . . might be. . . who wants to know? :D

well i thought £5 for all four doing is not a bad price and as far as i know all kwik fits have it as well as a number of other outlets. Also its becoming more popular +++

think nissan specify it on the GTR?

Never tried it myself - presumably they don't create a vacuum before putting the nitrogen in, so don't get a perfect fill?

In theory (if I wasn't conned) I have nitrogen in all but the O/S rear.
No difference I can detect and no difference in temperatures during use.
I was conned wasn't I. He didn't put nitrogen in did he:(

Now I've got to try Kwik Fit, so I know. A fiver sounds so cheap, was that the lot or per wheel?

My 'air' was free! Is that cheap or what?
