There's nothing wrong with the wheel, it's just rigged to give out junk 90+% of the time.

Load your Churchill up with armor/health emblems. Range/speed bonus helps it too.

Wait till the enemy gets almost into range of your LT then send out churchill & super pershing to intercept. Your LT will help them hold off the initial enemy push. Send tank destroyers and damage mediums behind as support. Use cannon special to clear mines & damage groups of enemies. Once unlocked, use the healing special to keep the churchill alive.
