You can rent a movie, a car, furniture or electronics of various kinds. And now, you can rent tires. You read it right: rental tires. They are, it turns out, a growing business. The price of rubber is going up, which means tires are more and more expensive. That’s where these tire rental places come in. Their marketing says: if you depend on your car to get to work, but you can’t afford to buy four tires, rent them instead.
