Discover why poor wheel alignment on your car costs you money.
I was once privileged to be involved in a Goodyear demonstration where they had a toy vehicle that allowed them to adjust the wheel alignment of the front tires. The vehicle was allowed to run down a ramp onto a flat surface with various alignment settings and a measurement was taken of how far it traveled before it stopped. I was surprised by the effect the wheel alignment had—it really was dramatic.
Have a look at what the Environmental Protection Authority has to say on the Fuel Economy Impact Analysis of Reformulated Gasoline. Their figures show that bad wheel alignment could cost you 10% or more in fuel.
