|Always overfill your tires
car myth masqueraded for decades as an insider's tip for getting
better gas mileage with less wear and tear on your tires.
It does neither, according to Martin.
"You want to keep your
tires at the recommended pressure because if they're over-inflated,
they wear one way, under-inflated they wear another,"
"Try to get even
wear and rotate your tires every 7,500 miles."
"It doesn't make a whole
lot of difference on mileage," says the Oregon-based automotive
writer. "As far as wear goes, it's better than under-filling
them, and the reason is, for every pound that a tire is under
the recommended pressure, it will run hotter and wear faster.
"If you ran a tire
five pounds under the recommendation, it would last probably
20 percent less."
