Lexus GX Tyre, Wheel, Centre Bore & Torque Specifications Guide
Complete Fitment Guide for All Generations | Autosport Tyreworld
Overview of Lexus GX
The Lexus GX is a premium full-size SUV built on a rugged ladder-frame chassis, sharing its DNA with the Toyota LandCruiser Prado. Known for its off-road capability and durability, the GX platform features strong wheel hub design, large centre bore, and high torque wheel nuts — all critical for safe wheel and tyre fitment.
This guide covers all major Lexus GX generations:
- GX 470 (J120)
- GX 460 (J150)
