Re: OEM 2015 Altitude Wheels on 2016 Limited TPMS ISSUE
Frequencies are still the same, but 2016 pressure systems are not compatible with earlier models. I know from extensive experience on the subject.
If it helps you out I have a set of new takeoff 2016 sensors from a 9 mile 2016. I'll sell them cheap, but you have to buy replacement stems as the newer sensors stems are not reusable once removed (apparently). Luckily new oem stems are available on eBay for 8 bucks shipped for all four, or tire stores might actually stock them. New stems just clip in place. I'll do $30 shipped on them. PM me if you're interested or text at 847-769-7307 and I can send pics as well.
