Tires on 2014 Sierra

[FLKyle]

Guys, I have a 2014 Sierra 1500 Z71 4x4 with a 2" leveling kit. Still have stock 20" wheels and 275/55/R20 tires on it. Looking to put a new set of BFG T/A KO2 on it. Looking at three tires:

 

LT285/55R20/D

LT275/65/R20/E

LT285/65R20/E

 

I really want the biggest tire possible but don't want heavy rub. Anyone have any thoughts experience with similar setup? Any thought on the load class D vs E?

 

Any info will help. Thanks.

I have 275-60-20 BFG KO2s, 2" level, no rubbing whatsoever. There should be room for 275-65s.

Thanks. If anyone has the 285/65/R20 I would be interested to hear how it worked out.

I just put a Supreme Suspension 3" spacer at the top of my strut. I have 305/55r20 and they're riding fine

Did you add a bigger block in the rear? If so what size? Hows it sit? I have a 2" front but would like another inch atleast in the front and rear.

Stock in rear, but will likely change to a bigger block.

Outside, better idea of stance.

What size tires are you running 33s? Id be curious the height from ground up to the bottom of fender to compare to mine and see if it would actually give me another inch. Looks like it is taller though. Why did I have to come across this lol. Here goes more $.

They're 305/55r20, so I think about a 33.25". The truck is on the alignment rack but I can get some measurements. I'm super happy with how it came out.

I run a 275/65 r20 and don't have any issues. Slight rub on passenger side carpet if turning hard. Hasn't warranted a zip tie yet. I love the look of taller tires

Ziptie? My tires ate rubbing the inner fender when turning sharp. What's the Ziptie trick?

Pulling the carpet liner back with a horizontal zip tie. Read through the level thread and it is very common.

The top of the wheel well is @ 40.25"

 

I didn't measure the rear because it's stock with the bigger tires.

Thanks for the measurement. I will compare in the AM.
