I have seen a lot of different formulas about the forces acting on a wheel. So now I don't know what to use. So, I have a vehicule with 4 wheels ( Ø 200 x 50mm) with a load of 900KG. I want to know 3 things: 1. What power I need to start the vehicle to move. 2. What power I need for...

I have here some questions. 1: In the formula you don't count with the radius of the wheel. So if you have a big wheel, small wheel with some kind of width it is the same force you need to let the wheel roll?? 2: How do you know the coefficient? In my case I use a cast iron wheel diameter...
