The Cadillac XT6 is a mid-size three-row luxury crossover based on the GM Lambda platform — the same platform as the Chevy Traverse and Buick Enclave. It competes against the Acura MDX, Volvo XC90, and Lincoln Aviator. Tire selection should prioritize quiet ride and all-season competence — this is a family hauler that needs to feel like a Cadillac.
Cadillac XT6 tire sizes
The XT6 Sport trim uses 235/55R20 on 20-inch wheels. The Luxury and Premium Luxury trims use 235/65R18 on 18-inch wheels. Some configurations use 235/60R20 on 20-inch wheels.
Both FWD and AWD configurations are offered across trims. The AWD is a disconnect system that favors FWD unless wheelspin is detected. Verify your exact size on the driver door sticker.
