I've created a list of every compatible tire from Tire Rack. Effectively, this eliminates anything with a load index of 113 or lower.

It's split into three sheets—one for each wheel diameter. There are some filter views (Data > Filter views) to filter by type, or you can create your own temporary filter view.

A note on weight:
  • I'm not convinced that wheel/tire weight is that big of a factor for efficiency, especially compared to a tire's tread/compound ("rolling resistance").
For the last point, this could probably be its own thread, but despite all the conjecture across car forums, the only semi-scientific test I've seen is Tire Rack's:
TireTotal weight (lbs)Average speed (mph)Fuel economy (mpg)
Michelin Energy MXV4 Plus (Grand Touring)42.538.722.8
Pirelli P Zero Asimmetrico (Max Performance)38.539.021.5
Pirelli P Zero Asimmetrico (Max Performance)48.538.821.1

Comparing the first and second wheel/tire combination, despite a 9.4% weight saving, and 1% difference in speed, fuel economy went down by 5.7%, all because of the tire's rolling resistance.

Comparing the second and third wheel/tire combination, despite a 26% increase in weight, and 1% difference in speed, fuel economy only went down by 1.9%.

tl;dr: weight probably isn't as big of a factor as you think.

21 list looks so lonely

Another data field that would be good is tire weight. Some of the Plus 1 sizes for 22-inch fitment are true all terrains and Load Range E ... but weigh as much as 20 lbs more per corner! That’s a lot of inspiring mass to add. So even though they match the 20-inch tire’s 34-inch size, they’re heavier than 33-inch XL rated options (and way heavier than the efficiency-biased OE P Zeros).

Yep. After owning a BMW i3 with its "completely custom to it" tire sizes is exactly why I *didn't* pick the 21" wheels for my R1T.

Would you kindly consider placing the OEM tyre on the very top so we can compare? Forgive me if I missed it.

22” should include Continental TerrainContact H/Ts.

This is great! Another reason why I didn’t go with 21” wheels.
