Hello guys, i have a 05 crew cab z-71, i bought a set of 20 inch rims with a street tread tire which are now wore out and I want to goto a at or mud tire, my question is how big can i go at stock height and how big with keys in front, i have 285/50/20 now but want to go bigger? any help or anyone running 20's with keys or with stock height, thanks in advance

D

 

I ran a 33x12.5x20 with a levelin kit so you could run that if you want

 

Thanks sir, 33/12.5/20 what is that a 305/50/20? Or 305/60/20

 

it's a 305/55/20 if you want it exact

 

thanks, is that the pic of them on your profile? and did you just use keys or did you do keys in front and blocks in back? i found a key and block set on eaby 2 inch front and 3 inch blocks in back for like 150.00, thanks for all your info, just dont want to buy the wrong stuff and have them rub

 

yeah I did keys and a 3" block in the back. the bolts that are on your keys now, keep em. they're longer than the ones they may send you and provide just a little more lift cause 2" won't be enough
