2013 4x4 ccsb biggest tire size?

Have a stock truck.I'm looking to put 20x10 -20x14 rims on it with 33s .can I get away with cranking the torsion keys a little or do I have to lift it? Any advice would be greatly appreciated.

No one knows?? Guess I'll find out

whats the offset?

20x10 fuel rims with a -12 offset tires are 305/50/20 I just ordered everything...wondering how high I'm gonna have to go to get it to clear

Well for the 213 ppl that looked n don't know how to post info I'll let ya know ....
2013 ccsb lml 4x4 cranked the keys up .top of fender is at 41" with a 20*10 -12 offset fuel throttle rims nitto 420s 305-50-20 .close to stock height n the truck barley rubs. Its been a week n is starting to wear the plastic inner fender away where it meets (about 2"x2") I'm not complaining.-scott
