If you're buying the TL rims from someone local, maybe you could meet up with them and just change one tire to see if you get any sort of error. Even if you know it'll work, I would suggest doing a test fit just to make sure the bolt pattern and hub bore are the same. Also, if the sensors aren't compatible, you could always replace them with new ones and try to sell the old ones to someone who still has a TL.The rims from the 2004-2008 TL will fit the TLX. I found a set I want to buy for winter, but the TPMS system is making me hesitate. Anyone know how the system in the 2004-2008 TL works? I've read that some Acura systems have "initiating" sensors that broadcast the signal so no TPMS programming of the car is necessary when changing wheels (the car automatically recognizes which wheels are on what corner of the car). I'm wondering if the 2004-2008 TL sensors will be recognized by the TLX?
If they are it will be simple to change my winter rims on and off without the PITA programming at the dealer.
