No...could be any combination of loss pressure per tire. Example; 1 tire with a 2 lb. loss another with a 1 lb. loss another with a 3 lb. loss and the last tire with a 2 lb. loss, the total will equal 8 lbs. and the TPMS will trigger. Now on the other hand if you have 3 or all 4 tires that are low and do not equal 8 lbs. or 25% loss the TPMS WILL NOT trigger. That is why it is important to check tire pressure weekly or bi-weekly.
