Car wheel not working… Help!

I’ll get straight to the point. I’m using a Hinge Constraint set as a Motor to spin a circle like a wheel. This works perfectly however, it stops spinning the wheel if I attempt to change the size of the wheel with code. I’m not sure why that is but I need it to spin as the wheel grows in size. I’ve tried both using a tween to increase the size and a while loop but no matter how i attempt to change the size of the object, it always stops the spinning of the wheel while the growth is taking place. Help!
