My kit came with a new set of lug nuts or lug bolts. Do I need to 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 even vary between models of the same carmaker. One difference is the lug seat or what is referred to as the "seat type." Other differences may be in sizing and thread pitch. Modern Spare makes certain that if your vehicle uses a lug type that is not compatible, we will include a new set of lug nuts or lug bolts that are proper for your car. 

If your vehicle requires lugs other than the factory lugs currently on the vehicle, the lugs will be shown as an included item on the packing list included in your shipment. 

If a new set of lugs is included in your spare tire shipment, be sure to locate 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?
