Lug Nuts are what keep your Pontiac Montana Hubcaps on your vehicle – so I guess you can say that they’re pretty important. Whenever you remove your Lug Nuts, whenever you change or rotate your 
tires, or whenever you install those bolt – on hubcaps, make sure that you properly torque your Lug Nuts every time.
Official proper installation requires that the wheel lug torque actually be set to the recommended specification that already comes standard on your vehicle. The torque values can be found in your owner’s manual – that way, you don’t have to go & bug the dealership.
You’re welcome,
Mykalanne.
