Hey everyone, just found this forum, figured I would drop a line and say hello, thx for having me. Iv been a proud owner of a Telluride for approximately 1 Month. Of course my experience is giving to me by my wife, she loves it. So I'm happy with that fact. I do have a question about the tires, I've noticed a green tire stem cap. Does that color indicate something other than air goes in tire? Also, tire says never exceed 40 psi. But the digital display on dash reads 50 psi. I purchased new from dealership. Am I missing something? Input on both would be sweet!!
