Mine are now filled with 100% Nitrogen (Kwik Fit)

I was advised that other than the more constant tyre pressures the gas was friendlier to the alloy wheel itself?

Same as, kwik fit 1.25 corner, will i see frost if get puncture?

Had mine done today and when i went to pay was told FOC, the branch shall remain nameless.

I think Costco did it FOC when it started doing nitrogen. Not sure if they still do though

Last time i asked at Costco they would only do it if you had your tyres changed with them

Do they fit and inflate the tyres in a nitrogen filled room ???? or just in the workshop with all the common or garden tyres that get pumped up using good old fashioned AIR

And now the science bit:
The rubber tyre is like a membrane, through which oxygen permeates three times faster than the nitrogen. The result is that the oxygen slowly leaks out through the rubber walls, and the under-inflation leads to higher tyre wear with a consequent decrease in safety and comfort, and higher fuel costs.

All clever stuff, so when the 6 litres of normal air have leaked out through the rubber the pressure will be stable, so how long does it take for 6 litres to leak out, or to put it another way how soon can you stop checking your pressures, and how do you top up when the tyre place is closed ??

God knows, but I know all mine leaked out instantly when I ran over a nail  2019 BMW X3 2.0i M Sport in metalic black- Brilliant

2012 - dearly departed, sadly missed.. to return in late 2013 with a new TDV8!

I have some snake oil for sale...

my wife has a freelander, we ( i ) bought it new in 2005, it has done 25,000 miles, is still on the orginal tyres, i now check them every quater, and i pump them up maybe once a year, though they have never lost more a couple of PSI in a whole year, she must have magic tyres 07,TDV8,Black, Black Heated leather all round, Rear Entertainment with Headpones & Remote, TV, DVD, Pure Dab Digital Radio, Sidesteps, Adaptive Headlights, sunroof, now working fuel burning heater )))

its just a way to get the people who are blinded with science to part with cash.......
