tyre pressure shock
checked my tyre pressure for the first time today after 10 months 
i used a sainsbury auto one where u set the pressure.each tyre was at 29 psi.so i pumped em up to 32 psi.
the results were my teeth started rattling and the back end seems a bit lighter
should i trust a supermarket tyre gauge...?

10 months? 
i try to check mine every week or two...
had a nasty surprise in the past when i discovered my driver's side rear had a slow puncture and only 23psi in it - this was after doing a 180 after planting it on a corner... thankfully no damage, except to my trousers!...
i got a digital one and checked the pressures against the local supermarket - they claim the same pressure and it feels fine to me...
shell's airpump the other side of town is set high compared to the other's though... and i don't use esso cos they charge 20p which i think is ludicrous on principal...

does anybody use special air,like deoxygenated and dried.
is it true that the is200 comes with nitrogen in the tyres instead of air and would this alter the handling.
and yes i know air mainly cosists of nitrogen.

OFN - Oxygen free Nitrogen gas is used in F1, race car tyres, karts etc as temperature and humidity has very little effect on the tyre pressure.
Normal air has loads of moisture in it and will alter in volume when temperature changes. Hence why you are supposed to check tyres cold at an average of about 15-20C. The air expandes as it gets hotter and this doesn't happen with OFN.

would helium reduce the power to weight ratio

we're driving Hondas not TVRs, although I'll probably check mine this weekend now, as I haven't done it since the service 3 months ago
