hi I am new to this smart thing (just picked up a pure orphan last week) I am going to need winter tires. I found a set on steel wheels for a great price, but since they are a few years old they are pre sensor. I found sensors at tire rack.for a decent price (40 bucks each). I will of course have to have the sensors installed. Do they need to be 'programmed' by a dealer? or is it something anyone…
