Using the Tesla Model 3 as an example, the 2023+ models with 18" wheels use the Michelin ePrimacy in 235/45r18. The models with 19" whels use the Hankook Ventus S1 EV03 in 235/40r19.
Michelin says the following about the ePrimacy:

The ePrimacy has no treadwear rating, but based on its reported lifespan, I'd wager it would be around a 600, give or take.
Hankook says the following about the Ventus S1:

The best balance between wet and dry performance.

The Hankook has a 280 treadwear rating, and is an Ultra High Performance tire.

So, in the case of the Tesla, the 18" vs 19" is apples to oranges. The tire mounted on the 18's is a LRR eco tire, while the 19 gets a high performance tire.
In the case of the G5 Prius, the 17" get BluEarth-FE AE30, while the 19" get BluEarth-GT AE51. Just going by the names, the 17" is a F(uel)E(fficient) tire, while the 19 is a G(rand)T(ouring) tire.
