iskyfly, run your tyres at whatever PSI you feel comfortable with! Never ever over-inflate your tyres for better fuel efficiency, better of with a lighter wallet than dead!

Over-inflation and max PSI are two complete separate entities, you need to realise this. If someone runs at max psi, they are not running over-inflated, they are still within the designed tolerances of the tyre.

Also, I would suggest if your car becomes unstable if you deviate from the car manufactures recommended air pressure, then either a) it is a **** car or b) you have damaged components.

Running at whatever pressure the tyres are designed for, be it at 30 psi or 50 psi, then the car should still handle adequately.

An over-inflated tyre and an underinflated tyre will bother wear incorrectly, but especially the less air in the tyre, the quicker they wear out due to heat build up. Max psi usually gives you perfect wear right across the tread pattern. Running them soft usually causes feathering at the edge and at least causes them to taper off at the sides, which come wet weather, is much more dangerous if you ask me as you have less contact with the road.

But again, it's whatever YOUR comfortable with! YOU make the decision.
