The 2026 Tacoma trim ladder
The 2026 chart breaks into 4 factory sizes: 245/70R17 (30.5 in) on the SR and SR5, 265/65R18 (31.6 in) on the TRD Sport and Limited, 265/70R17 (31.6 in) on the TRD PreRunner and TRD Off-Road, and 265/70R18 (32.6 in) on the TRD Off-Road i-FORCE MAX, Trailhunter, and TRD Pro. Tire size on a 2026 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: 2026 Tacomas run 17-inch and 18-inch wheels. 2 of the 11 2026 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 2026 sizes fit the 4th gen Tacoma
Zoom out and 2026 is one year of the 4th gen Tacoma (2024-2026), whose common factory sizes are 245/70R17, 265/70R17, 265/65R18, 265/70R18. The 4 sizes on the 2026 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.

2026 Tacoma tire size questions
A 2026 Toyota Tacoma came from the factory with 245/70R17, 265/65R18, 265/70R17, and 265/70R18, depending on trim and package. SR and SR5 run 245/70R17, TRD Sport and Limited run 265/65R18, TRD PreRunner and TRD Off-Road run 265/70R17, and TRD Off-Road i-FORCE MAX, Trailhunter, and TRD Pro run 265/70R18. Confirm the exact size on the driver's door placard or the tire sidewall before you buy.
TRD Off-Road i-FORCE MAX, Trailhunter, and TRD Pro carry the tallest factory tire on the 2026 chart at 265/70R18, about 32.6 in of overall diameter. The shortest is 245/70R17 at 30.5 in on the SR and SR5, a spread of 2.1 in across the range.
No. The 2026 Tacomas we cover run 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 2026 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.
