Tesla’s 2025+ Model Y service material lists different tire sizes by wheel diameter, including a staggered 21-inch front/rear setup.
Identify the vehicle generation first
The 2025+ service table is not proof that every vehicle sold as a 2025 Model Y has the same factory package. Confirm build/generation, wheel option, door placard and installed tires before using a size.
Keep front and rear separate
The 21-inch setup lists 255/35R21 at the front and 275/35R21 at the rear. Do not order four identical tires from a single size filter for that setup.
Check Tesla-specific requirements
The service table also identifies Tesla T-marked replacement tires. Read Tesla’s current service guidance and exact part revision before choosing a replacement.
