Tonight I mounted a set of 2004 Comp-G 17" 10 spokes with Blizzaks on my wifes 2008 GXP. Strangely, the TPMS isn't complaining even after driving it for 15 minutes or so. Is it still trying to "learn" the sensors or something ?? We did buy it used with 21,000 miles so I don't know if it was programmed out or something but I really would be surprised if the guy if the guy I bought it from goofed with the pogramming .... confused.
