Will these wheels fit ?

I found a set of mayhem missle 20x9.5
He says they fit a chevy 6 lug pattern

I want to put 33x12.50 on them
I have a 3 inch level in the front so I can hopefully clear them

Will they fit ?

 

20" rims, 33x12.50 tires and the 4 banger..... Going to be the most gutless truck in town, maybe even the whole planet.

 

Nevermind guys I found a great deal on some 285/70/17
Would they work ?

 

Would be a much better option in my opinion. You'll still want to regear though at some point. I had a 97' with the 2.7l & 33x12.50x15 tires & 5th gear wasn't usable unless I was going downhill. Would lose speed even on flat ground lol. I just went from stock to 31x10.50x15 tires & could notice a drop in power. Little harder getting started from a complete stop on hills now too.
