We just installed new tires on our Jetta where this is just an observation in which I thought would provide some interesting discussion. If you go online to question what tire pressure is best for your vehicle, the response you will find is to follow the vehicle manufacturers recommendations on the door jamb, fuel filler door, etc. With this in mind, whenever we have taken our passenger vehicles in to be serviced by a tire dealer, we have yet to have them inflate the tires to this "recommended" pressure. Why would you say this is?
