Hey guys long time,
I have an 03 Denali which I love to death, and I saw that the 05s had the self testing valves on the tires. My question is can I buy them? Or do I have to buy the ones that change color? That would be cool too though. How does it work on the 05s? Is it like the vettes that show a read out on the dash? Also what does it cost?
Any help would be appreciated.
