Are you looking to bolt on a spare tire to your favorite short course truck but prefer the look of a single spare tire versus the appeal of our Dual Spare Tire Carrier (RPMÂ #70502)? Our Single Spare Tire Carrier is an excellent option! It is a simple add-on that allows you to bolt on one functional spare tire to the back of your truck, perfectly mimicking many popular full-scale off-road desert trucks running in some of the toughest desert conditions out there.
