Tire inflators are increasingly capable and autonomous, which makes them far better at their job than they used to be. They can reinvigorate a sagging tire in a few minutes with the touch of a button and without further oversight. This is because most modern tire inflators have an auto-stop function, which can be set at the desired level of air pressure. This makes pumping up tires a far more convenient and streamlined experience, especially compared to the hand pumps of old. These days, keeping tires at a safe inflation is no longer much of a chore, thanks to powerful modern tire inflators.
