21 Rapid Red ST - new owner

[HTinstaller]

Hey everyone. Traded my 17 Silverado z71 for a 21 Explorer ST with the high performance pack. I plan on keeping it mostly stock since I favor reliability above performance. I plan on searching in this forum for info, but here are some of the items I’m interested in now: -I have 21” wheels, what are the best tires to get? I live in KY, so all 4 seasons here. I favor a good ride and low noise. Tire rack is recommending Pirelli Weatheractive. Anyone have those? -How can I tell if my ST has any kind of tune? -I can tell the exhaust pipe from the engine bay has been replaced. Carfax said the dealer replaced the catalytic converter. Is that what I’m seeing or is that aftermarket down tubes? -recently found the passenger rear footwell has been damp under the floor mat. Not a lot, but enough to get musty. I am assuming this is a clogged sunroof drain. Anyone had this? Where is the drain line? Like I said, I plan on researching for answers, but if anyone had experience with any of these, I would appreciate pointing me in the right direction. Thanks!

Welcome and congrats!!
Check the drain holes in that tray above the battery. They are notorious to get clogged and soak the floor.

Will do. Would that be for the rear passenger footwell or the front passenger footwell?

I misread your post. I was thinking front passenger. Sorry about that.
If you have wet floors second row it could be the sunroof drains.
I believe the drains exit just behind the rear tires somewhere.
If you have wet floors in the back near the hatch I think there was a TSB awhile back on those rubber grommet’s for the wire harness on the hatch that leaked water.
