So after some research I seem to have cracked the STHP code in the ETIS database (in case you can't get access to the Monroney window sticker). Note: these findings are based on the 2015 model year so YMMV. The Monroney will include these 3 items under Optional Equipment; 245/45R19 99Y Summer Tires - No Charge Handling Package - $1565 19" Polalum Whls W/ptd Pkts - No Charge There appear to be 2 items that will indicate the car has STHP in the ETIS Minor Features of the report; Enhanced Interact Vehicle Dynamics 245/40 ZR 19 BSW Like the hybrid they also did not include a spare tire with the STHP option so you will also see these 2 additional items in the Minor Features report; Kit - Tyre Repair Service Less Spare Tyre In a normally equipped car the above mentioned Minor Features will read as follows: With Electronic Stability Control 245/40 R 19 Less Tyre Repair Service Kit Spare Tyre - T125/70 D17 Happy hunting!

Fascinating thread, any luck OP?

I just started looking at previously owned 2013-2016 MKZ's. I would like to find one with the Summer Tire Handling Pkg. My understanding is this option required the Reserve & AWD options. Also, from I can glean from the old MKZ brochure the car would have been equipped with the 19" Polished Aluminum rims with Painted Pockets. Any tips on how I determine for sure if a car has this option either with or without the Monroney sticker?
