Wheel rotation help cant work out the problem?

Hi Everyone hope your having a good day so far

I need a little bit of help with some wheel rotation I set up for my game I can't seem to work out why my wheels are moving 3x faster than acceleration speed of my car

have I set something in the inspector too high cause I'm thinking it might have something to do with my wheel script that i have setup with the car
