The 2018 Tacoma trim ladder
The 2018 chart breaks into 4 factory sizes: P245/75R16 (30.5 in) on the SR and SR5 4-cylinder, P265/60R18 (30.5 in) on the Limited, P265/65R17 (30.6 in) on the TRD Sport, and P265/70R16 (30.6 in) on the TRD Off-Road and TRD Pro. Tire size on a 2018 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: 2018 Tacomas run 16-inch, 17-inch, and 18-inch wheels. 1 of the 5 2018 configurations we cover is 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 2018 sizes fit the 3rd gen Tacoma
Zoom out and 2018 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 2018 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 caution for 2018: this model year is not proven against a year-specific Toyota document, so every size above is the common factory pattern rather than a verified trim-level spec. 2017 through 2020 share the same factory tire lineup, and 2018 sits inside that span. Confirm the exact size on the driver's door placard or the tire sidewall before you buy.

2018 Tacoma tire size questions
Our data puts a 2018 Toyota Tacoma on P245/75R16, P265/60R18, P265/65R17, and P265/70R16 depending on trim and package, as the common factory pattern for the year rather than a sourced trim mapping. SR and SR5 4-cylinder run P245/75R16, Limited runs P265/60R18, TRD Sport runs P265/65R17, and TRD Off-Road and TRD Pro run P265/70R16. Confirm the exact size on the driver's door placard or the tire sidewall before you buy.
TRD Off-Road and TRD Pro carry the tallest factory tire on the 2018 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 4-cylinder, a spread of 0.1 in across the range.
Read the tire and loading information placard in the driver's door jamb: it lists the original tire size and the cold pressures set for it. Then check the sidewall of the tire actually on the truck, since sizes get changed by previous owners. For 2018 our trim mapping is the common factory pattern rather than a year-specific sourced spec, so the placard is the authority.
