everytime I go over a pot hole, new tyres?
anybody tried nitrogen in their tyres?

According to a DETR leaflet i have the maximum fine for a tyre defect is 3-6points and 1000 PER defect. So 2 defects could be quite a severe situation....

Tyre condition is something i think is important....!

Well, judging by the number of tyre threads currently showing up in "What's New?", it looks as though this has jogged a few people into action.

Speaking of which, anyone know any good tyre review sites?

Ted, how about adding a Tyres section to the Reviews part of the site so people can give their opinions on wet/dry grip balance of the Yokohama A520 compared to the Dunlop SP Sport 9000.

I got nitrogen in my tyres. Pressure stays pretty constant; even adding a bit of air to it for a few experiments has no ill effect.

Different gases in the tyre.

we all put normal air in our tyres, but what would happen if you put another gas in there. e.g hydrogen or nirogen...?

Also when your car is moving does the air inside the tyre move also?

Well I guess Hydrogen would reduce the unsprung weight!

no, hydrogen is lighter. shame its explosive

more of a blow up than a blow out then

Why don't manufacturers put up technical info on their site. Tyre related info would be one of those things. Select you vehicle type, options etc. and have a list of recommended consumable details: Tyre sizes, recommended patterns, pressures, brake pad part number/size, oil type, spark plug type etc.

Air is 70% (ish) nitrogen, 20% (ish) oxygen and some other gases (carbon dioxide, noble gases etc) so the benefit off using pure nitrogen is that as it's one type of molecule in there, it's carateristics are more uniform, pluss the abscence of oxygen helps reduce the chances of the tyre decaying on the inside (UV is still the biggest killer of tyre though)

All the molecules in air are constantly whizzing about all the time, but I would guess that the rotation of the tyres would also cause the a drift in the motion of the molecules in the direction of rotation, but their motion will still be faily random.

This is true - get pulled over with a set of bald tyres...3 points per bald tyre...bye bye license!!!

Nitrogen doesn't have anything like the pressure change of air as the tyre heats up, if you know what I mean. Thats why F1 teams fill their tyres with pure nitrogen. It makes setting tyre pressures easier, because it doesn't change by a huge amount as the tyre heats up

You can get this from your dealer or Haynes manual.

By using pure nitrogen you don't have any water molecules in your tires as you would if you used ambient air. As your tires heat up, the water molecules apparently expand significantly, which is why your tire pressure changes.

I've got nitrogen in the tires of my daily driver, which was pretty much a waste of 2 euros/tire, but sounded cool at the time! No noticeable difference, but I wasn't expecting any either...

If I had to replace a tyre every time I hit a pot-hole I would have to get the council to set up an account with my local tyre dealer!
