On Board Air Options??

[crotchrocket]

As my rear seats are now removed and i've had two occasions where i have un beaded a tyre and needed a tyre guy to take my tyre off and re-seat it i am going to build a decent rear boot build. i.e tools, compressor subs etc. Means i can also let the tyres down in muddy conditions etc

My options are;

a simple single cyliner pump. Will be enough (just) to inflate the 33" tyre

a twin cylinder pump, faster and tougher

The other idea is to have a 2 - 3 gallon tank hooked up to a pump. however im not sure if that will work on the pumps above? i.e the tank is pressurised and the pump only kicks in when the air pressure in the tank drops to a pre-determined pressure?

this means instant and powerfull air for re-seating an un beaded tyre as you need it to POP back onto the rim.

The other advantage of this is i can hook one of these bad boys up to it and get back at the people that cut me up daily in London

The options are anoyingly small for this set up if the pumps above don't work with an air tank as i cant find a 12v compressor linked to a tank in the UK.

Could get this

with a 1000 watt power invertor? May be handy to have 240v in the boot at some point anyway?

Other option is this, a proper set up but bloody expensive
