20's were 295/60/20, 18s are 285/70/18

 

18's definitely look better. Nice looking truck.

 

thank you, rides soooo much better.

 

18s or even 17s are so much better looking than 20s on an F150. This is just a personal opinion. It's nice also not to worry about curbing your nice wheels especially in those poorly built curved drivethrus where they decide to build curbs on both sides lol.
