Rotate a wheel script?

I am looking for a simple way to just rotate a wheel ( in a car etc ) in a constant speed and with the pivot in the center but cant find a good way and dont find a sollution on the web either.

how about just rotate the circles with the rotate tool and copy and paste the keyframes for however long you want, or use onion skin and rotate for every cell until you get a full turn and copy and paste the keyframes for however long you want, of course you vary the speed to go faster using fewer frames or more frames for slow, and you have the option to use squash and stretch for dramatic action, don’t know about using a script

Thanks,
Thats a good idea if you want to create something more cool and not stiff.
I have been trying to find out if there is a way to set pivot in exact center- option but I havent found one.

just use the Translate Tool or Rotation Tool to set it manually wherever you want, remember to insert a keyframe before starting you animation and then copy and paste keyframes on the timeline with either control v or click the paste icon near the main menu
