The only things holding each of your wheels to your axles are your lug nuts or bolts. These high torque fasteners are able to withstand the incredible rotational forces that are applied to them at all speeds. It is important to always have perfectly sized lugs for your wheels and vehicles, which is why, if you have installed a set of Ford Racing wheels on your Ford, you absolutely must have the right Ford Racing lugs to go with them. There are a lot of different sized lugs out there and the wrong lugs, even if they seem like they fit, can spell disaster. The right Ford Racing lug for you is going to be a certain diameter and length, and it will have a certain shape to its head if it is a lug bolt. Always torque your Ford Racing wheel lug. A lug that is too tight can fracture itself or the wheel, and a broken wheel can either fly off or catastrophically lose air. Lugs that are too loose will almost certainly fall out, allowing your wheel to fall off of your vehicle, which is almost certain to end in an accident. So be certain to always use the right sized Ford Racing wheel lug and to torque it properly to keep both you and your vehicle safe from harm.
