I've got a new 2018 Ford Explorer Platinum with the OEM 20" Bright painted wheels, and I'm starting to look into winter wheels and tires. I've Googled all over but not finding much luck with these 2 issues:

The TPMS. Are these the same as previous years? What frequency range? Rock Auto has 3 different parts listed - F2GT1A180AB, F2GZ1A189A which are 315MHz, and another set that are 433MHz. Can anyone shed some light on which work? And if you buy a set online, do you need a special tool to relearn the system?

Also, the brakes. What is the minimum radius that will clear? 17"?

TIA
