Default Equivalent tire size but in a 20” or 18” wheel?

I’m looking for the equivalent tire size to factory (275/50/21) but in 20” or 18”. I’m purchasing method race wheels in either size today but need need to match an A/T or R/T tire.
These pics will show you why I’m swapping and to whoever designed this 21” wheel, they are beyond stupid for leaving gaps at the back of the spokes.

LOL! I'm not sure about 18" wheels but on 20" wheels, you can use 275/55/20 or 275/60/20 - the 275/60's look a lot better. 55's shown below.

You can use Land Cruiser wheels and 18" tires (285/60R18). Or even Sequoia/Tundra wheels and tires. Sequoia/Tundra 275/65R18 have a slightly large diameter than Land Cruiser tires (about 0.5" diameter difference) but it's not a problem.

thanks! I think I’m going to have to try and run 285/60/20 at least for during hunting season. That’s all Toyo offers in the RT tire range and their AT is offered in a 275/55/20 but it’s not the “Xtreme” so it looks awfully bland.

I picked 18's as I didn't think the difference between oem moronic 21's and 20's would be enough. My 200 has Toyo AT II's, 285-70R 16's on a set of very inexpensive zero mileage Tundra take-off wheels. No issues in dirt, where it is about half the time. I can feel the advantage that the taller sidewall provides. Winter tires are Blizzak's mounted on 18" oem aluminum wheels.

Xtreme's are readily available in 18", as you probably know.

Generally, a 3-ton (unloaded) vehicle has no business on a set of passenger-rated tires, imo.

to be completely honest I love the look of the 21’s but can’t believe they aren’t solid on the back side of the spokes and then only having the single tire choice.... but I ordered black 20” methods and paid $420 for them. I think I will run them from Sept-Feb and then run OEMs through spring/summer.
