It is impossible to tell exactly how much you save, due to varying fuel prices, cost of tires, and how much you drive annually; however the installation of Tire Pressure LED will reduce both fuel and tire costs. Having under-inflated tires or even only one under-inflated tire will mean increased fuel consumption. Additionally, the thread of the tire is worn down faster, reducing the life span of your tires. Under-inflated tires are also dangerous for the fact that they can trigger blow outs, making Tire Pressure LED essential for safety and saving lives. Research shows that 80% of all vehicles have one or more tire with an average of 25% under-inflation. Using these figures given, the average vehicle is using an average of $300 more per year of fuel than it would with the correct tire pressure on all tires. Additionally, even slight under-inflation can reduce tire life by up to 50%. Only you know the exact value of your tires and can figure out what your savings will be.
