How fun—we hope you have a great (and safe) trip! Unfortunately, the 2018 Toyota RAV4 does not have a spare tire. Toyota made this decision for the 2018 model so that drivers could enjoy extra cargo space in the rear—but it came at a small price.
That said, if you load up luggage and have extra cargo space, you could technically fit a spare tire in the trunk—it would just take up some room. But it’s not a bad idea when you’re taking the RAV4 out for a longer trip where you’ll have less access to roadside assistance and mechanics.
