I'm wanting to get new wheel to replace the factory 17" 8 hole wheels that came on my 05 f250. I've found one that i really like but don't understand how offset and backspace plays into wheel choice. I need new tires and plan on going with a 35x12.50. So could someone please explain to me what this is and how it works. I don't want to end up buying a wheel that won't work right for my set up.
