well kwik fit have now become an agent for a nitrogen tire filling company.costs 4 pound too have 4 tires purged of the compressed air and refilled with nitrogen
going have done in the week and see how they compare

 

Whats the difference?

 

you will end up having new brakes , some shocks , 4 new tyres and a c*ck in your *** by the time you leave though ! there are plenty of places doing nitrogen filling and have been for ages , will you see any change hmmm prob not ,

and as for even taking your scoob to kwic fit ,

 

On a road car? Bugger all really... pressure is more stable with temperature variations and they supposedly maintain their pressure longer (i.e. leak less) but I'm not convinced of any real benefit.

 

But great to tell your mates down the pub

 

They have been doing nitro for a long time....

Well my mates site has.

 

 

+1

They have been doing it down here for a while now but I would rather have my eyes removed with rusty spoons than take my car to Kwik-Fit

 

we call them quick d-ick

 

When i was younger i had a full GP250 ride. With full backing from Michelin and two of their technicians every race day, we ran nitrogen filled tyres. The funny thing was on week day practice ( just air filled tyres) we were only a few seconds off weekend race times per half hour but this my dad put down to less pressure on a practice day as to riding for first place on race day.

The only difference i could feel was less tyre flex as though you were running higher tyre pressures but with the grip of a lower tyre pressure.

 

haha i had my tyres filled with nitro by kw a few months back, made a massive difference in ride quality.... it rides pretty much the same all the time now, with normal air it did change with the weather - hot/cold - soft/hard!

 

I agree probably no benifit to doing road wheels

double post again

 

Isn't air 78% Nitrogen?

 

i can get big bottles of nitro from boc on company account so no probs there

 

Yep 78% Nitrogen. Hard to believe it will make much difference on a road car, fair enough on an F1 car where every millisecond counts.

cant get thicker than a quick fit fitter

 

Can't see it making any difference at all, except to the wallet and some of the more sensitive bum dyno's LOL

 

Can't believe that it makes £4 of difference myself.

TX.

 

had it done to my 3 series last year and was great coming off motorways on to country lanes....

Never had to top up either!

 

Excuse me being curious but what was the difference coming off motorways onto country lanes?

And how often do you check your pressures?

 

I've noticed that the ride quality doesn't vary as much as it did with normal air and the tyres do not get as hot when driving hard (road) I do recommend all you guys try it out, surely £4 isn't going to break the bank and no i dont work for kwick-****

 

You having a fvcking laugh?

 

As you say not going to break the Bank

I will have to do my track wheels done as the Pressure can massively change during the day

I have had the RE070's set at 34/32 and after a few warm up laps handling went really bad checked Pressures 52/41 (n/s as a right hand circuit)

So will try Nitrogen to see if it lessens the increase

Tony

 

I use a 78% nitrogen mix for the best possible price/benefit compromise.

 

Same^

Is it even possible to purge all the air out of the tyres anyway? Likely not I think.

So a rough guess would assume an extra 10% nitrogen in the tyres.

Gimmick.

 

No it isn't. And when I used to work in an aircaft tyre bay (couple of decades ago now) the spec for aircraft nitrogen allowed 5% oxygen IIRC


Wonder what Kwikfit's Nitrogen spec is.........

 

the company who supplies the machice too kwik fit also supplies ats and demon tweeks.if you look on uniflate.com theres all the information and benefits.the machince is programmed too do the work.for 4 quid if it saves checking for few months etc it aint going break the bank.nissan gtr has nitrogen in tires so it not just for formula 1.granted kwik fit got bad rep but surely just plugging a machine in aint going hurt.im going try and see how compares too air.how many people check there tires rigurous each week...and have the spare 20 p for the garage and hope the machine is calibrated regular etc.plus having seeing compressures working in industry you can see moisture coming out the air line at times.have a look at uniflate and see what you think

 

Check all my cars weekly with a decent pencil gauge and use a plug in compressor (aquired from the boot of a Porsche I once had) to top up.

Much cheaper than 20p (40p at Tesco now!) and much more reliable than hoping the pressures are ok cos they got four quids worth of nitrogen in them.

Nitrogen still changes pressure with temperature, like air. The lack of moisture makes the change more predictable (hence F1 use). Have tyres Nitrogen filled on a warm day and they WILL be underflated on a cold day...

Some F1 teams were still using air (thru driers) as recently as 2005 and my understanding is that they have swapped to Nitrogen so they don't have to maintain air compressor driers. But they still adjust the pressure to the temperature of the day and the expected temperature rise on the track. F1 tyres typically run around 100 to 130 degrees C which is why they need to know exactly what the pressure rise will be.

 

wow thanks for all the replies...looks like i started quite a debate ..thanks all
