What tires come standard on a Toyota 4Runner?
There isn’t a single tire specification for every 4Runner; it depends on trim and year. For the current fifth-generation model, base SR5 and SR5 Premium run 17-inch wheels with 265/65R17 all-season tires; TRD Off-Road and TRD Pro trims wear BFGoodrich All-Terrain KO2 tires in 265/70R17; and Limited models ride on 20-inch wheels with 275/55R20 tires.

Notes on regional and model-year variations
Tire specifications can vary by market (North American vs. international models) and by model year as Toyota updates wheel/tire packages. If you’re shopping used or considering a specific dealer lot, always verify the exact tire size listed on the vehicle’s door placard or in the owner's manual.
Summary
Among fifth-generation Toyota 4Runners, tire choices are not uniform. Base and mid-level trims use 17-inch wheels with 265/65R17 all-season tires, off-road-oriented trims (TRD Off-Road and TRD Pro) use 265/70R17 BFGoodrich KO2 all-terrain tires, and the Limited model employs 20-inch wheels with 275/55R20 tires. Always confirm the exact size for a given vehicle, as regional variations and mid-year updates can change standard equipment.
