No, 30-inch wheels are not compatible with all vehicles. The compatibility of 30-inch wheels will depend on the make and model of the vehicle, as well as the specifications of the vehicle's suspension and braking systems. Some vehicles may require modifications to the suspension or braking systems in order to accommodate 30-inch wheels, while others may not be compatible with the larger size at all. Before installing 30 inch staggered wheels on your vehicle, it is important to consult with a professional and to thoroughly research the compatibility of your specific vehicle.
