[Closed] Nitrogen filled car tyres?

Planning on entering Le Mans or driving at 30,000 ft ?

The molecules are larger and don't escape. They don't react as much to changes in temperature.
Lot's of the superbike boys use it in there tyres.

So the AA reckon it's a load of pap. Thanks for that, I was thinking along those lines myself. 🙂

Let's go back to the beginning - what on earth were you doing on the KF website and once there do you really believe anything they say?

I do believe I've already answered both those questions if you care to actually read what I have already written, or do you need me to copy and paste the text in for you again? 😛

Air is approximately 80% nitrogen so Shitfit are obviously overchaging - should be 20p a wheel 😉

Square root of F all difference...

It's not going to do you any harm if you want to get it done, but you won't notice the benefits for certain!

So if you keep topping up the air pressure in your tyres, you will be eventually be left with only nitrogen molecules 💡

.........and will have saved yourself four quid 8)

Costco put it in for free when you get the tyres done and supply free top ups.

I have learnt, through expensive repairs to my car, to never ever believe anything that kwickfit tell you. Dont let them do any work on the car, at all.

They managed to destroy the front end of my corsa to the point it needed new cv joints, new shocks, new shock mounts, new springs, new track rod ends, new wheel bearings and new tyres due to the quality of the work they performed.

They lied to me every step of the way.

I know you are only buying tyres but please go else where. Cheaper in the long run!

You cant get shitter than a Kwik Fit fitter 😆

Try filling your tyres with co2 and then go for a ride a week later. Nitrogen does the opposite. Pretty much like air does.

Not any more they don't. Nitrogen was used in extemely hot conditions a few years ago, but nobody uses it anymore as there was no real advantage.

The only place you'll find nitrogen on a superbike now is in the front forks and rear shock. On a MotoGP bike it's also used by some teams to run the pneumatic valvetrain, but most stick with good old compressed air.

Wheelz is correct with the use of nitrogen in motorsport. We did alot of testing with Dunlop on our GT cars and found a small improvement. The problem you have is that you have to purge the tyre first of all the air before you add the nitrogen. We now just use compressed air but its not actually the same air as supplied by your local garage or home compressor. We use a diving compressor which runs a drier filter to remove as much of the water as possible.

Just wondering why?

out of the big boys in terms of tyre centre's it's only Kwik Fit that offer nitorgen as far as I'm aware, Ats and National certainly don't offer it to us at work.
Although as a company we don't pay the extra as the benefits arn't worth the extra cost even at £1 a corner.

I remember nitrogen being promoted for truck tyres a few years ago as it varies pressure less with heat. At up to 11.5t per axle, truck tyres can get very hot.
On board tyre inflation was another option. Automatically adjusting tyre pressure to suit the load and compensating for slow punctures.
Neither of them caught on.

Clearly it's baloney, but what do you expect from kwikshit?

I popped in there the other day just because I was passing. They wanted £276 for 2 tyres that cost me £140 elsewhere.

And they have a big sign outside saying "lowest prices"!!

D miller, water expands with heat ,thus affecting tyre pressure. AFAIK

I assume the method for bottling nitrogen is fractional distillation of air? If so, then the process is energy-expensive so it's not exactly an ecological thing to do, is it?

The tyres on my Mango IF have Nitrogen inside them rather than air just because we use it at work and I used the bottle of GN2 instead of getting a pump out!

Just fro information the atmosphere is 80% nitrogen anyways so unless you are planning on driving with extreme temperatures in your tyres I don't really see the point
