My kit came with a new set of lug nuts or lug bolts. Should I use these when mounting the spare?

Yes. For some vehicle models, the factory lug nuts or lug bolts are not compatible with the spare wheel. For these vehicles, we supply a new set as part of your spare tire kit.

The types of lugs used on modern vehicles are not standardized across all manufacturers. Lug types can vary even between models from the same carmaker. One difference is the lug seat, also known as the "seat type." Other variations may involve sizing and thread pitch. Modern Spare ensures that if your vehicle uses a lug type that is incompatible, we will provide a new set of lug nuts or lug bolts that are suitable for your car. 

If your vehicle requires lug nuts or lug bolts that are different from the factory ones currently on it, they will be listed as included items on the packing list in your shipment. If a new set of lug nuts is part of your spare tire shipment, make sure to find them and only use those when mounting the spare tire.   

Why do some vehicles use lug bolts and others use lug nuts, and what is the difference?
