Re: Off road ability with 20" wheels without selec-terrain
It isn't necessarily the lack of Selec-Terrain that gets you. It's what that lack means. But to really explain it, a little foundation first...
There's three different four wheel drive systems on the WK2:
1) Quadra-Trac 1- full time AWD, front/rear torque split fixed at 50/50, single speed transfer case (no 4x4 LOW range). Selec-Terrain is not offered with QT1.
2) Quadra-Trac 2- full time AWD, front/rear torque split is variable, two speed transfer case (there is a low range). QT2 is where you pick up Selec-Terrain.
3) Quadra-Drive 2- basically, QT2 with a rear electronic limited slip differential (instead of using the brakes to limit slip as with QT2). Only available on Hemi models (and even then not all of them), still has Selec-Terrain.
Short version is that without Selec-Terrain, you have Quadra-Trac 1, which is NOT intended for anything approaching serious off roading. You're likely also missing tow hooks and skid plates, which can be added, but without a low range you may find yourself rather limited in what you can do. You also don't have the hill descent control (useful on very steep descents).
And this is all before the 20" wheels... there just aren't any all terrain tires for these because it's pretty much screaming aloud for a bent rim if you go crawling over rocks.
In short, the vehicle you're looking at is a an on-road or soft road SUV (you'd be hard pressed to go anywhere something like a Ford Explorer won't). If you want off roading ability, you need something equipped differently.
