My door jam label says 36 on front and 49 on rear I believe. Every time they have been rotated is has caused this light to come on shortly afterward. (The mechanic said he checked/adjusted them.) The first two times pressure adjustments corrected it but the third time the dealership replaced all four. From now on I will only get my tires rotated where they can reset it to make sure the warning light will stay out. Don't you just love mandatory new technology .
