Guys and gals I just picked up a 2016 Tesla X Tutanium and the tires are not great they will need replaced. I've seen some YouTube vids w people testing 21" Turbine S wheels on the X. I have a like new set of grey 21s from my last S I was considering trying with new tires. Larger of course. Anyway has anyone done this or have tire size recommendations or info for me? Thank you.
