Smoothly keyframing a wheel to decelerate from point A to B
For good or bad, in Davinci it's all about maths. Since you want to move the wheel you will change position x/y and rotation, as you mentioned. But you will have to add time points and make the calculations (i.e. if you want to speed up/slow down, change move/rotation direction etc).

For example you want to have the motion for 5 secs, 1 full rotation lasts 1 secs. So you are gone have something like that: 

time=0s x=-200, rotation=0
time=1s, rotation=360
time=2s, rotation=720
time=2.5s, x=0
time=3s, rotation=1080
time=4s, rotation=1440
time=5s, x=200,rotation=1800




I hope to help you out a little.. :)
