Tire size

. The tires on my car are in really bad shape (215/70r15) and it is my only running vehicle. I have two vehicles that are not running one with a tire size 235/75r15 the other with 205/60r15. My husband does not get his pay check until next week and we plan to get new tires then. Would the tires from one of my other vehicles fit my Lincoln until then? I am afraid for him to drive it with the tires that are on it. Thank you in advance for your help!
