Put some new tyres on my wifes Fabia and was offered a nitrogen fill with all sorts of claims of increased grip, tyre life etc. Only £1.50 a corner, so no big deal, but does it make any difference?

 

Any thoughts?

The main advantage is that nitrogen particles are bigger than oxygen, so they do not leak through the rubber. This means your tyre pressures don't go down as much as with normal air which has an 80/20 mix nitrogen to oxygen. Any adjustment you needed to make in future would cost you again? The rest I suspect is BS.

Bit of a thread here from a while back http://www.briskoda.net/forums/topic/312466-use-of-nitrogen-in-tyres/

 

Personally, I think it's waste of money, but them I'm half Yorkshire. 

My local ATS euromaster did mine (all 4) once a month I pop in and they check the pressures and top up with nitrogen all for free!

They even carry out free puncture repairs (provided its is repairable) but then living in a small town has its advantages and it is service like that, that gives them repeat business and their prices are competitive

No idea on advantages of nitrogen other than its stability during temperature changes.

My Superb tyres used to go down all the time. Sealing on the alloy wheels was poor. Nitrogen solved the problem.

Have run cars with/without and never seen any real benefit.

 

On the GT-R it's supposed to have Nitrogen in the tyres, with and without I noticed a two degree heat difference in tyre temps after a hard track session.

 

On road, no difference at all.

Will it affect the Warranty as the car came from the factory with air in the tyres. Will it have to be Skoda Approved Nitrogen  

The air in your tyres is already 78% nitrogen, 20% oxygen and 2% other gases, so please explain how replacing the 22% is going to make any difference, other than to your pocket?

I was wondering this the other day. Very interesting!

Mates got a slow puncture on his vw caddy. Might be worth trying this

Cheers

I see no real need for it however IMO the loss is normally down to water vapour on the air that is being pumped in, hence my airline at home and work have 2 water drain offs, one at the inflator and one at the compressor

Has he had the tyre dipped in a water bath to check there's a puncture he can't see? I ask because SWMBO had a slow puncture, I looked all round the tyre and couldn't see any damage. A dip in the local tyre fitters tank showed where it was coming from, anD further investigation by taking the tyre off the rim showed a nail that had actually gone into the tyre so wAs invisible from the outside

You must live on a very long straight road

Whist looking for a thread where someone actually asked if they should go to their dealers and fill tyres with genuine Honda air, I found this on here.

He hasnt got that far yet mate.

Its actually all 4 wheels though. The valves arent leaking, checked that.

I was wondering whether it could actually be the alloys? Or is that not possible?

Cheers!

Potentially yes, all 4 could be cracked, very long shot, or the contact surface between rubber and wheel could be rotten or full of crap causing air leaks.

As mentioned, nitrogen molecules are larger than oxygen molecules this resulting in a slower rate of pressure loss, also less corrosion as there is no moisture is pure nitrogen

Yes, but since the air in the tyres is already 78% all you are replacing is the remaining 22%.

Do you really think it is going to make that much difference?.

I stand by the assertion that if oxygen is that bad at staying in a tyre, they'll end up being full of nitrogen anyway. :-)

Sorry, personally no I dont think its worth it. Yes true, the air we breathe is made up of 78% nitrogen, 21% oxygen and a few other elements. To get the so called benefits for tyres, nitrogen needs to be at least 95% pure, the only ways to do this would be to add an extra 10-15% nitrogen to get rid of as much oxygen as possible or unless the dealer used a vac pump to remove air from the tyre before filling with OFN. As mentioned, based on cost, performance "benefit" etc etc, I personally wouldn't recommend, its a waste of money

(sorry for going slightly off-topic)

If this is true, then the proportion of nitrogen will increase over time, even when it's topped up with 'normal' air.

It's a waste of time, but partly because I've never had a garage actually fill tyres to the correct air pressure in the first place.

 

(Has anyone ever had a garage ask if they carry heavy loads, or mostly cover motorway miles?)
