Tyre pressures

[sumotan]

For sure its will loose air. If I park the car for a week all tires will loose about 0.8 - 1 psi .

Disagree, when mine is in use during summern its checked weekly, losses are pretty much nil over months!
If you are losing air at 1psi a week continually then I would think you hae a leak somewhere, although at 1psi a week its not a worry of course

Well if that's the case it cannot be that consitent across all 4 tires right ?

Not quite sure how you come to that conclusion, not great at explaining things in writing so - To help -
When the cars in regular use pressures are checked weekly, no real loss ever seen on any tyre.
When i checked mine fresh out of storage the tyre pressures on each axle had dropped identical amounts - it makes sense as a result that the cause is dropped air density due to lower temperature.
If i had a cracked rim, defective Vv, puncture, porous tyre, bad rim seal etc then one tyre would lose more pressure.
Hope that makes more sense - not a tyre guru just my thoughts on the matter
