Leveling kits and wheel offsets

Anyone have any ideas for what degree offset to use on a 2018 tundra with a leveling kit and falken 33 tires ?
Trying to get my tires away from the upper control arm by about an inch and a half already modified the skid plate to keep from rubbing at full turn

 

I just did a 33” 305/55/20 on a 2016 tundra trd double cab 20x9 fuel wheel with a +20 off set. No rubbing after mud flap removal. Amp terrain pro tire. Tires poke out past top of stock fender 1” or less

 

Forgot to add that I did a 2.5 in front spacer lift and a 1” block lift in the rear

 

I did a 3-1 leveling kit on mine but the rubbing isn’t my concern. The upper control arm and the tires are about a 1/4 inch apart in the front and it gives me anxiety lol
I modified my skid plate to get rid of the rubbing

 

What's the width of the tire? I'm looking to go 3-1 and use Falken but want to run 285/65/20 so that is going to put my width at 11.2 and worried about UCAs.

 

hey man it all depends if your adding fender flares, or want a more aggressive look I would go with a +1 if you want it to be closer to factory fender go +20

I did not level my truck its factory with a 20x9 +1 I added the flares I did a 275/60/20 which measures about 33 inches just not as wide I did have to melt the front plastic a bit

 

I think mine are 12” wide

 

Not sure if it's possible on factory rims and 34.5"s. Not that wide, but just don't know.
