I didn't know where to place this so thought I would try here and see what type of response I got. Anyhow, I air my tires up before each trip at Discount Tire and ck them during the trip before leaving each campground. The guy at Discount said he put 80psi in each tire, but when my monitoring system comes on line the pressure varies from tire to tire by anywhere from 2 to 8 psi, is that normal? How much off can these systems be and still be safe? If one says 80 psi and another shows 75 psi should I be concerned? I thought these systems were supposed to be pretty accurate.
