The amount to install the tire can depend on the shop you choose and even the type of tire. Some tires that you choose, especially the ones placed on heavy-duty trucks, will be more expensive to balance and mount compared to the ones for a lighter-duty truck.
Most shops will charge you between $15 to $50 for mounting the tires on a light truck. If you have a larger truck, then you may spend between $30 to $70 to get this done.
