Default 20 tire size question

I have a 3" front drop and 4" rear drop on factory Chevy wheels. Im running 275/55/20 factory*tires*now.
I have some rubbing on tight turns.
I want to go with a tire set that wont rub and wont look stupid.
Was considering a 255/50/20???

Open to ALL suggestions and input

I have an 2008 Sierra Denali AWD with a 2/3 drop. I have spindles and shackles with rear block removed. I have stock 20in. Denali wheels on 305/50/20. I want to bolt on the new GM 5656 wheels. They are 22x9 with +31mm offset. Will these work or will I rub? I know that's what the stocks are but they are 20x8.5. Also what size tire will look as good as the 305/50/20 in a 22 without rubbing? Thank you for the advice.

I am running a 265/45/22 front and 285/45/22 rear, I only rub on larger bumps or taking freeway on ramps at higher speeds.

I recently purchased a complete belltech 4/7 kit from you. Got it installed but not real happy with the ride. Even with the bushings installed it still wont align to factory specs. Negative camber. Sitting on factory 20s with 275/55/20s. Took it to the lake (curvey hilly winding roads) and could not have felt anymore unsafe and disappointed. Every little bump in the road would jerk the truck around and shimmie the wheel in your hands. Bump steer is absolutely horrible. I expected to be some what nimble through the curves, not scared shitless. Not unhappy with suspension source but belltech is junk. I lowered thruck for handling and looks. Is there something else I can do to get the camber corrected and get a suspension that handles good?

Shoot me a message or give me a call. Let's go over everything in more detail. This is an unusual to hear.

Im looking at getting front end down app 3 " by any means I can

Nobody I know of makes dropped spindles (I asked McGaughy to make me a custom set, he wouldn't be in it) Nobody I know of makes custom control arms. I can get down a bit but need to go lower than the camber allows for and still have my tyres standing upright

I am considering grafting an early model (04) setup to get available dropped spindles (and the option of bigger brakes as well that also aren't available)

I appreciate any imput you may have. Thanks
I am by no means any expert with the suspension on 2011 and newer 2500's but I know that there were different torsion bar spring rates for 2010 and older trucks. Maybe ones from a gasser would have a lower spring rate thus lowering the front end???

I would go with the Belltech spindle and strut up front, Belltech flip kit in the rear with Street Performance shocks.

This kit will be the one. Ignore the STD cab part. It will work on Crew Cab/Ext Cab too.

07-13 Chevrolet Silverado/Sierra (Std Cab) 0" to -4" Front / 7" Rear Drop w/ Street Performance Shocks
