Can someone please explain how wheel spacers would ultimately have an impact on rubbing. I'm sure a lot of us are well aware of the dubs build and I would rather not buy spacers if I don't have too. I would like someone to explain how they influence the wheel spacing in terms of pushing them further away from the wheel well but also making it closer to the truck when at full turn? I plan to put BFG 35s with boss Coilovers on my lariat and want to verify they will fit and not have to worry about rubbing or trimming. I have 20" rims on my lariat.

Thank you everyone for all the help this far. Really appreciate it. Have a good day!

 

BFG's 285/65/20 will not rub with stock wheels. They wont rub without a lift. Everybody thinks the lift is making the truck clear the tire for some reason not sure why. Wheel spacers will make it more likely to rub. The turn angle changes the farther the wheel is out. Easiest way to see this is just get something round on your desk and draw the arc at two different spots visualizing the turning of a wheel.
