Have you checked your tire pressure lately? If not, you could unwittingly be lessening the lifespan of your tires by a pretty significant margin. Believe it or not, according to Tire Rack, "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%." Not only does this ultimately cost you money, but it can also be dangerous if you're expecting your tires to last 25% longer than they actually do. Luckily, the solution is simple: Just keep your tires inflated! There are tons of reliable and affordable portable air compressors available on Amazon right now that allow you to quickly inflate your tires in your very own driveway. Most even come with tons of extras like built-in flashlights, bike tires attachments, sports attachments and more. Starting at under $30, these tire inflators could save you a trip to the gas station for a top-off or a call to AAA for a tow.
