I'm not one to install a tire size thats not called for on the door jam for my 2020 sr5. I had a brand new set of 265/70 16 goodyear adventure tires i bought for my gen1 tundra, but sold it just before buying the tacoma. They fit, and work fine for what i use the truck for.....pretty quiet on the highway to.
The way these trucks are geared, imo, be careful selecting a tire that doesn't weigh a bunch. I can tell you i doubt i'd install a heavier tire than these.
