Run flat tires can temporarily support the vehicle after pressure loss, allowing you to keep control and drive a limited distance to service. Note that they require a compatible vehicle setup and a working TPMS system.
EV Compatible means the tire is marked as suitable for electric vehicles, where load, torque, rolling resistance, and noise can matter more.
Vehicle Type helps identify whether the tire is intended for passenger, light truck, commercial, or similar service categories.
Warranty coverage is manufacturer backed and depends on normal use, proper maintenance, rotation, inflation, and alignment conditions.
