The Lexus GX is a body-on-frame luxury SUV built on the Toyota 4Runner/Land Cruiser platform. Unlike most modern crossovers, it has true off-road capability: solid rear axle on the older GX 460, and the GX 550 continues on a ladder frame. Tire selection should balance Lexus cabin refinement with the off-road capability the platform can deliver.
Lexus GX tire sizes
The GX 460 (2010 to 2023) uses 265/60R18 on 18-inch wheels across trims. The GX 550 (2024+) uses 265/55R20 on Premium trim, 265/50R22 on Luxury, and 265/70R18 on the off-road-focused Overtrail. Verify on the driver door sticker.

Best all-terrain tires for the Lexus GX
BFGoodrich All-Terrain T/A KO2 (265/60R18, 265/55R20): the standard all-terrain upgrade for the GX, available in both sizes. The GX platform is capable enough to use a proper AT tire, and the KO2 maintains reasonable road manners while adding off-road confidence.
Falken Wildpeak A/T3W (265/60R18): the quietest all-terrain for the GX 460 on 18-inch. Lower road noise than the KO2, 3PMSF-rated for winter. Strong choice for GX owners who do winter travel.

Should I get all-terrain or highway tires for my GX?
It depends on how you use it. The GX has real off-road ability, but if yours mostly does pavement and school runs, a highway tire is quieter, smoother, and longer-lasting. If you actually take it on trails or gravel regularly, an all-terrain's grip and tougher sidewall are worth the small noise and fuel trade. Match the tire to your real driving, not the badge.
How do I know when my GX needs new tires?
Check tread depth with a quarter at 4/32 and a penny for the legal limit. On a heavy body-on-frame SUV, also watch wet stopping distance and any vibration, and inspect for cuts or chunking if you run it off pavement. Don't ride worn tires on a vehicle this heavy; it stops on its tires, not its size.
