While changing my tires for the winter, I checked my tire pressure and it was low (30psi) compared to the car recommended pressure (35psi).
This made me curious as to what the minimum tire pressure is for my tires and I could not find it. I know that both under and over inflating tires is bad, but I was curious what would be considered the minimum is.
Nokian (My tire manufacturer) says the following:
The correct inflation pressure will be provided by your tire retailer; if not, refer to the vehicle decal. These inflation pressures must be maintained as a minimum. However, do not exceed the maximum pressure rating indicated on the tire sidewall.
To my understanding, that means I should always stay between 35psi and the maximum rating. However, I also heard that this is the recommended pressure for the way the manufacturer wants the car to handle. (Can't remember where I read this, sorry)
Just how low can I go before I damage my tires from low pressure?
It seems like the number in the door panel is the "minimum" according to current answers. Why is that the case, how does the weight of the car affect the minimum pressure for "all brand/models of tires"?
