Fitting 33" Tires (285/75R16) to a 90 Series Prado: A Guide

This document provides information about fitting 33-inch tires (specifically 285/75R16) to a 90 Series Prado, based on user experiences and modifications.

Problem

Fitting 33" tires to a 90 series Prado typically requires modifications to avoid rubbing and ensure proper clearance, especially during off-road articulation.

Solution

The following modifications and considerations can help accommodate 33" tires:

  • Lift Kit: A suspension lift is generally required. A 40mm suspension lift alone may not be sufficient.
  • Body Lift: A 50mm (2 inch) body lift can provide additional clearance.
  • Wheel Offset: The correct wheel offset is crucial. A ‘0’ offset is one option. A -25 offset was also used.
  • Front Guard Liner Trimming: Trimming of the front guard liner may be necessary.
  • Body Seam Grinding: The body seam behind the front guard liner may need to be ground down.
  • Mud Flap Removal/Modification: Front mud flaps may need to be removed or reshaped.
  • Lower Control Arm Adjustment: Winding the lower control arms forward can improve clearance.
  • Bump Stop Extension: Adding approximately 1 inch to the rear bump stops can prevent tire scrub.
  • Hot Air Blower: Using a hot air blower can reshape the front mud flaps to prevent rubbing.
