Frequently Asked Fitment Questions
Click below to expand direct answers to the most common fitment queries for the Toyota 4Runner Gen 4:
What is the bolt pattern and center bore for the Gen 4 4Runner?
The Toyota 4Runner Gen 4 (2003-2009) utilizes a 6x139.7 bolt pattern and a 106.1mm center bore. Ensure your aftermarket wheels are hub-centric or use high-quality hub-centric rings.
Can I run 33-inch tires on stock suspension?
Yes, but it requires highly specific offset wheels (generally around stock offset) and minor trimming of the fender liner to clear full steering lock.
What is the factory offset and how does it affect rubbing?
The factory wheel offset is +25mm. Moving to a lower or negative offset wheel pushes the tire outward. While this creates a aggressive wide stance, it increases the scrub radius, which can cause tires to rub the rear of the fender liner and the body mount.
