No problem...we have used the PPros on the rubber stems that can with the unit so far without any problems, but will switch to metal when we replace the tires... So far we have been very pleased with the PPros, and feel they ass a new dimension of safety and peace of mind on the road. We do watch the tires and cold pressure very carefully and check the tires (and lug bolt torque) before every trip...and is part of our "getting ready" routine.
