My experience over all of the vehicles I have owned is I like my tires half way between the recommended pressure and the tire's maximum. I was going to look up my stock tire's max since they are in my shed still, and look up what my owner's manual says.

Since I no longer have stock tires on my 1302, I apply the percentage of the midpoint-to-max of the stock tires to the max of the current tires to generate my new figures.

I hope my explanation is clear. I will look up the figures that apply to my car when I get home tonight as an example. (I keep the results in my glove compartment.)

I think my method offers better handling.

If I drive any amount fully laden, I use the same method but I have different figures with which to use with most cars. If I drive any amount in the rain, I will drop the pressure down to the recommended.
