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.
