If you are going season to season without ever having to put air in your
tires, you are one lucky guy! ;) Air molecules expand in the heat and
contract in the cold. You should notice more air leaking out in the cold
than in the heat of summer. Always check your tire pressure when cold as
that's what most tire manfacturers require. That way, the ambient air
temperature will dictate how much air you put into the tire.

Re: Tire pressure
 

Dennis,

Air pressure in a tire is directly proportional to temperature. In the
absence of other forces, you will gain or lose about 1 psi for every 10
degrees (F) temperature change.

You should always check the tire pressure when the tire is 'cold' with cold
meaning that it had been driven less than 1 mile or sat parked for more than
3 hours.

Generally speaking your tires will gain about 4-5 psi during normal suburban
driving and more at highway speeds.

Everyone should own an accurate tire pressure gauge and you won't be likely
to find one in the 99 cent bin at K-Mart.

If you haven't a compressor or bicycle pump you can stop by the gasoline
station or tire dealership and add your preferred tire pressure PLUS 5 psi
and before you go to bed tonight you can bleed the pressure down to the
exact pressure you want. If PLUS 5 psi doesn't make it when the tire is
cold add a bit more the next day until you get your required pressure after
a bleed down.

You will find that tire pressure variance and loss is less if you have 100%
Nitrogen in your tires instead of just air and yes, I am aware that air is
80% Nitrogen.

As you are using oversized tires the pressure you need is probably less than
shown on the door placard. Other users here can probably give you
approximate pressures and there is an easy way to double check in your
driveway. I'm sure someone else will chime in with the procedure and the
best was to appropriate the supplies from your sproutlettes.....

Pressure also varies with altitude so you don't want to be filling the
tires in the valley and bleeding them off at home in your mountaintop
cabin..

Re: Tire pressure
 

Only if you are getting that metric air, it doesn't quite fit correctly in
American tires.
