Try putting more air pressure in your front tires.
Probably closer to 45 - 50 psi instead of 30 -35 psi. They will turn easier, less taxing to the pump.
Like manual steering, it always steers easier if the vehicle is rolling just a bit. Those wider than factory width tires are adding to the problem.
Good thing you removed the spacers, as they make it even worse putting lots of added leverage on all the steering/suspension parts.
