Default 315/35R20 on rear of silverado?

Im looking at wheel and tires, would like to do 315/35/r20 on the rear and 274/40/r20 on the front with either a 4/6 or 3/5 drop. Will a tire that wide fit without rubbing??? Any pics would be appreciated!!

THANKS YALL

Here is the exact combo you are referencing....

Owner is a member here, maybe he will chime in on the wheel offset. He does have a 9" rear that may be narrower than stock so it may not be direct comparison.

That's my truck and I do run those sizes. My truck is lowered somewhere in the range you are talking about....its on coil overs and a 4 link so no exact specs. I just did a quick measurement in the garage and got 16.5" from fender lip to the center of the hub in the front and 17.5" in the back. I did roll my rear fenders to get them to clear. My wheels offset wouldn't help you since my rear axle is custom, but I'm running 20x9.5 and 20x11 in Continental Extremecontact Sport. If you measure your offset correctly you should be good to go.

His truck looks very proportional and aggressive. They really need some wide tires in the rear to balance out the size of the truck

The only concern of mine is that i have a step side with the composite bedsides. Maybe I can trim them a little if there is an issue. THANKS!!

The OEM one has been discontinued for a several years 15197873.

However I believe there is a repop that is available through Classic Industries. You might want to call them to see when they will be getting them.
