The RPM is pretty self-explanatory (the speed at which the wheel is spinning in revolutions per minute).
I believe Offroad is whether the wheel is on a paved surface (e.g. runway) or not. I'm not certain but it would make sense. (Either that or it's just if the wheel is touching the ground at all).
Not sure on Forward/Sideways Slip. I'd assume that would be some measure of how much the wheel is skidding forwards (i.e. along the direction of travel) or sideways (i.e. not along the direction of travel), but I can't say for certain.
Adjusting forward and sideways slip increases the tire grip. Basically it's fine tuning to prevent unwanted drifting and burnouts
I think off-road means it's grip on dirt
