Keeping your tires properly inflated might just be one of the easiest yet most overlooked forms of car maintenance out there. Although it might not be immediately noticeable when you're driving on under-inflated tires, that doesn't mean it's harmless. According to TireRack.com, "If a vehicle's tires are under-inflated by only 6 psi ... the tire's tread life could be reduced by as much as 25%." Luckily, thanks to sales like this one, it's super affordable and convenient fill your tires in your very own driveway with a portable air compressor. Check out these 5 best-selling portable tire inflators below, all on sale.
