As the poll suggests, do you use nitrogen in your tyres or standard air?
Is it beneficial? Detrimental? Irrelevant?
I use 78% Nitrogen 
I don’t think I’m likely to notice the pressure change caused by the tyres heating up/cooling down and I check my tyre pressures weekly anyway so I’m not interested in slightly reducing the rate air leaks out of the tyres.
I think I’m going to try hydrogen in my tyres. Will make the whole thing lighter so that it corners better.
Not sure in London but some garages in Coventry are offering it as a free service if you buy tyres from there
Should better fuel economy and handling the Nissan GTR has it as standard.
there isn’t an option for ‘i don’t know’. i don’t. why would i want nitrogen in my tyres?
It doesn’t expand/contract with temperature as much as air does so you should get a more consistent pressure as your tyres heat up in use.
Nitrogen molecules are bigger than oxygen molecules so they don’t ‘leak’ out through the rubber as quickly.
I don’t see either of them a a major problem anyway. Maybe there are other, more convincing reasons that I’m unaware of.
What a load of tosh. It’s like worrying about the altitude.
I suggest that if you buy gold audio leads you are just who they are aiming this product at.
Gold makes a bigger difference than you might think . I have seen the difference … and it was large … However my tyres have common old air .
You hear with your eyes? Or did you just like the colour?
One of my most long serving friends works Linn Hi Fi at the HQ surrounded by testing equipment http://www.linn.co.uk/ . Computer graphs showing various plug and lead preformance data … yeah I have seen a few :hehe:
Wasn’t this done as a car feature on Top Gear (in Japan)? Made it go faster, be more stable, grip better, something about tyre heat, be a sales pitch to add $$$ on the price???
Don’t think my bike goes fast enough to care about it.
I’ve been able to repeatedly and accurately tell the difference with Gold audio leads being swapped in and out. A friend is an AV installer, I was on site at some millionaire’s mansion with him helping program a home automation system, and we tested listening to Gold vs Plain. On the hugely high-end high fidelity system that the guy had, the difference (listening to classical SACDs) was audible. Just barely, but I got it right every time.
My interconnects use cheap leads. My radio kit on the other hand uses Oxygen Free Copper… 
In the last 3 months I’ve had Michelin and Bridgestone attend at the EAMG group nights. (The Bridgestone guy used to be the tyre technician to David Jefferies.)
Both dismissed it for road and track* use.
When a tyres’s fitted it’s full of air anyway so there’ll be a lot of air in it anyway.
-
- the only exception was for high level racing at Thruxton due to the long very fast right handers. They didn’t use it at any other tracks.
I think my point. Anything other than air is a bit of wasted time/resource on a road bike.
Now if I were running a Formula1 Grand Prix car team, I might have a different view on the matter for the competition cars. Perhaps the same is true for world class race bikes, but for road use, absolute borrocks.
If you can be ar&ed, check the physics and maths. See what a few degrees of heat make to tyre pressures, then do the same thing for altitude. Oh. You will have to do the sums for both ordinary air and exotic gasses.
It’s irrelevant.
my tyres are lucky to have decent profile, let alone expensive air… i’ll give it a miss.
Interestingly, I was considering going back to solid rubber when the Avons wear out …
The idea is similar as pressure fluctuations are minimised but the big bonus has to be that punctures are completely eliminated. Incidental with pneumatic tyres are there any performance merits in choosing between plastic, polished alloy, anodised alloy or stainless steel valve caps when used with the various tyre filling options. It would be useful if some knowledgeable person could draw up a matrix highlighting the pros and cons of each combination of valve cap and tyre filling.
Also if weight reduction is a factor in choosing between tyre fillings do the advantages of removing and discarding the valve caps out weigh the disadvantages?
So we’re pretty clear then
Irrelevant! :hehe:
