I heard that good tire pressure for a Mazda 626 is 32psi for the front and 26psi for the rear.

I have a tire pressure checker but mine doesn't have a psi rating, mine is in kg and lb. It's a strange tire pressure check because one side shows pressure in Kg from 0.7 kg to 3.5 kg, but the other side is in lb but goes from 10 lb to 50 lb. Now 3.5 Kg is not 50 lb . Anyone know a good tire pressure for my strange tire pressure device .

The side with the 50lb is the psi. The side with the 3.5Kg max is a pressure reading in kg/cm2. The 3.5Kg/cm2 converts to 50 psi.
