Top setting 5100...biggest tire without trimming?

I’m about to pull the trigger on 5100s on top setting, 1.5 inch shackles, and some spacers for my ‘19 Tundra XSP. I’m thinking of keeping the stock wheels because I like the look so that’s the reason for the offset spacer.

My question is, how much meat can I fit in the wheel well when it comes time for new tires. I’m running the stock trail grapplers currently. And will go bigger when it is time to change. What have you guys using the top setting of the 5100 ran in to as far as sizing/rubbing issues. Thanks!

 

I am running 285/60 20 With 5100 on top setting

Had to remove factory mud flaps but that’s it

 

Running 5100’s and 1 coachbuilder shim on factory rims with 295/70R18’s. Just pulled the front mudflats but no rubbing anywhere else.

 

Top setting on my 5100's with 275/65/20. Removed flaps and bent the skid plate a little.

Flaps removed, ran a 285/75/17 on top setting 5100s with zero issues. Nothing out back. 17x8 50mm offset wheel.
