On a stock defender the wheel size won’t really matter, tire width and height limitations will remain the same.
‘Something like 33 max height with around 11.5” width on stock offset rim.
Tires actual spec can vary quite a bit, way more than IMO they should be allowed to.
Always best to check the tire of interest factory specs for diameter and section width, tread width too if offered.
Not true. Try a 32.4" O.D. AT tire on a 20x9.5 ET25 wheel and I bet it will rub the plastic wheel well liners before reaching full steering lock. It is also easier to fit a narrow tire vs a wide tire with the same O.D. Case in point would be 265/70R18 vs 285/55R20 where the 20" tire is fractionally shorter but more likely to rub.

These examples are related to rim offset coupled with a 30mm increased tire width.
Reduced offset, use of spacers, excessively wide tire will limit you to less than the 32.6" maximum.
Installed 275/55/20 BFG Ko2 on factory 20” wheels. Zero rubbing with or without the 30MM wheel spacers installed.
Sorry for the beginner question, but did your height clearance change when changing to these K02s? I have 20" stock wheels/tires, but I have to park somewhere that I literally have centimeters of clearance as is (coil, no air suspension). I want K02s (can't wait for K03s), but really hope that it doesn't change my clearance.

This tire size (275/55 R20 )reduces your ground clearance and height by 0.05" or approximately 1.25mm
I installed a set of 275/55/20 Mickey Thompson Baja Boss AT tires on my 2021 D90 X-Dynamic with its stock wheels on Saturday. I highly recommend Tire Rack Mobile for its user-friendly service. It took the technician about 50 minutes to complete the tire swap. As others have mentioned, the fitment is perfect, and there’s no rubbing with my air suspension in any driving condition. However, the road noise is slightly louder compared to the stock Michelin tires, but it’s not unbearable. You’ll definitely notice the difference from stock tires, so if that’s a significant factor for you, I suggest considering other options. I personally chose these tires based on their snowflake rating, load rating, and positive performance reports from other users.
I’ll take some photos once I have a chance to clean up the truck, as it’s quite dirty at the moment.
