Hello, Hoping someone can help me out. I have 2003 Chevy Silverado lowered on 5/7 Drop. I've been looking at the Forgestar F14 Wheels. Hoping someone can help me find wheel specs for the best fitment. I want 20 inch wheel, but want widest wheel/tire i can fit on stock diff. I want wheels to be tucked inside. Looking for rear only wheels only but if you have a suggestion front ill take the info. So if someone has good specs let me know! If have any questions or misunderstanding what im trying to ask just LMK.
Thanks!!

 

I had a '03 Sierra sitting on Centerline Wheels 20x8.5 Front with 265/35 20 tires and had the rear wheels widened to 20x10 with 295/40 20 on a 3x4 drop.
Never had any issues rubbing, bottoming out or any other trouble. Well, other than loosing rubber on the wheel tires cuz the truck made 412 HP at the rear wheels!! Loved that 2nd gear bark at WOT, made me giggle every time I did it!!

Last I heard Forgestar was not able to place the truck's 6x5.5 bolt pattern on the normal F14 blank for the larger sizes. The drag series truck wheel is on a different blank. If you have information to the contrary, please share.

As for spacing, for a stock width axle, no more than 3.5" front spacing to keep the wheel/tire inside the fender. At 3.5" you will need to roll the fenders; 3.25 would likely tuck without rolling and 3" would completely clear. Not many tire choices unless you want to go real short. 315/35/20 on a 20x11 with 7.5" BS would fit nicely with very little gap on a 7" drop. Once you get much wider than that, leaf springs start getting in the way.

Obviously the best method is to get out the tape measure and confirm yourself.
