You can adjust the suspension settings to make them ridged, and you can use vertically oriented suspensions to prevent side wobble as if it was on rails. Wheels lack any form of propulsion on their own. They also lack any form of innate rotation ability. They're just cylindrical objects, exactly as they are in the real world (try welding a wheel directly to something sometime and see how well it spins). You need to provide an axle to them, and propulsion should you require it as well.
