1st gen... there are too many variables to list...
including using different wheel diameters..
But the factory wheel is generally 16" or 15"
so I'll start with that.
Factory/OEM BS = 4.5"
a 265 (10.50" W) is the largest acceptable tire size...
using the factory BS'd wheels and fitted correctly.
One exception is the 255/85/16 (is a 33" tire. but 10.30" wide)
^ this tire will require modification like TLT or comb. susp./body lift
For tires 33" (11.50" W) - (285/75/16)
4.0" - 3.75" (3.75" works best)
33's will need 3.50" total lift to fit.
^ 2.50" suspension lift, combined with 1" BL gets there.
3.50" suspension lift is unattainable and would be fubar'd to attempt.
A 3.50" BS wheel may stick out too far...
possibly require the fender lip be trimmed.
but might be necessary to fit wider 33's (X 12.50" W)
Suspension lift alone, is not a proper solution for fitting larger tires !
Excessively lifting the suspension makes you out to be a off road pretender.
a narrower 35" tire can fit in the wheel well @ 4.0 - 3.75 BS'd
some modification (tubbing Wheel Well)
plus some trimming would likely resolve many fitment issues.
The 12.50 width tire is lots more pita and with no real world gain.
A narrower tire works best for the Tacoma that has weak steering
components. Wider tires wear the steering components out faster.
If you must run 12.50 widths...
Get efficient at replacing steering racks and ITRE's.
If you pay someone else... gonna be a little spendy.
Suspension upgrades are still a must do..
but you don't need much actual lift.
