Car tyre pressure

  Is it better to have the tyre pressure fully pumped up until ur tyre got no 'belly' at all when you look at it.
  I heard fully inflated tyres are lighter to move off due to lesser contact on ground and thus saves fuel.
  But I aso heard that it requires a little more braking distance and can cause the centre patterns to wear out faster...
  
  Any comments anyone? Btw I driving a 4X4 jeep. Fully infalted tyre looks nice too...esp after the petrol attendants shine my tyres

  Under-inflation is one of the greatest killers of tyres. Tyres running at less than optimum pressures can suffer a 25% loss in tread life due to increased shoulder wear. They are also dangerous.
  
  Don't pump too much air into your tyres either. Gross over-inflation causes your tyre to bulge out at the centre. Which means that the centre of the tread will come into greater contact with road surfaces than any other part of the tread. So, the tread centre wears out earlier. Because an over-inflated tyre has a smaller surface area in contact with the road than properly inflated tyres, it suffers from reduced traction.
  
  Over-inflation of tyres also increases the risk of bruise damage. That happens when your tyre hits an object but you can't really tell. Tyres which are grossly over-inflated also create undue strain on your car's suspension.

  Advisable to pump air only when when the tyres are cold, and not after you have travelled half-way around the island! =P

  What's the best PSI number for say, my Extol van??
  
  Frankly, I am a fraid of pumping tyres - I have a fear of air-filled objects.
  
  It's a phobia.
