The larger size of 28 inch staggered rims can impact the performance and fuel efficiency of a vehicle. The increased weight of the wheels can result in decreased acceleration, as well as increased wear on the suspension and braking systems. This is due to the fact that larger wheels require more energy to spin and can also increase the overall weight of the vehicle. In addition, the increased size can result in decreased aerodynamics, which can impact the fuel efficiency of the vehicle. It is important to consider these factors before installing 28-inch wheels on your vehicle, especially if you plan to use the vehicle for off-roading or towing heavy loads.
