The 2021 Tacoma trim ladder
The 2021 chart breaks into 4 factory sizes: P245/75R16 (30.5 in) on the SR and SR5, P265/60R18 (30.5 in) on the Limited and Limited Nightshade package, P265/65R17 (30.6 in) on the TRD Sport, and P265/70R16 (30.6 in) on the TRD Off-Road, TRD Pro, and SR5 Trail package. Tire size on a 2021 Tacoma tracks the wheel and package a trim was built with, which is why the answer changes as you move up the range.
Wheel diameter moves with it: 2021 Tacomas run 16-inch, 17-inch, and 18-inch wheels. 3 of the 8 2021 configurations we cover are package- or configuration-dependent rather than a plain standard fitment, so two trucks wearing the same badge can leave the factory on different tires.
How the 2021 sizes fit the 3rd gen Tacoma
Zoom out and 2021 is one year of the 3rd gen Tacoma (2016-2023), whose common factory sizes are 245/75R16, 265/70R16, 265/65R17, 265/60R18. The 4 sizes on the 2021 chart are drawn from that family, so a tire that fits one year of this generation is usually available for the others in the same size.
A sourcing note for 2021: 2021 through 2022 share the same factory tire lineup, and 2021 sits inside that span. Nothing in the sources separates those years at the trim level, so the 2021 sizes are the shared pattern for that span rather than a year-specific table.

2021 Tacoma tire size questions
A 2021 Toyota Tacoma came from the factory with P245/75R16, P265/60R18, P265/65R17, and P265/70R16, depending on trim and package. SR and SR5 run P245/75R16, Limited and Limited Nightshade package run P265/60R18, TRD Sport runs P265/65R17, and TRD Off-Road, TRD Pro, and SR5 Trail package run P265/70R16. Confirm the exact size on the driver's door placard or the tire sidewall before you buy.
TRD Off-Road, TRD Pro, and SR5 Trail package carry the tallest factory tire on the 2021 chart at P265/70R16, about 30.6 in of overall diameter. The shortest is P245/75R16 at 30.5 in on the SR and SR5, a spread of 0.1 in across the range.
No. The 2021 Tacomas we cover run 16-inch, 17-inch, and 18-inch wheels, so wheel diameter changes with trim and package. Because overall diameter is the rim plus twice the sidewall, two 2021 trims can end up close in tire height on different wheels — which is worth checking before you assume a wheel and tire package moves between trims.
