BUYING A CAR IN 2010
(WITHOUT HAVING HEADACHES IN 2011)
experience doubly unpleasant.
Put
a couple of blocks of wood in the car to be used as chocks when changing a
flat tire. While it helps to set
the car’s brakes and transmission to keep the car from rolling, when a
wheel is jacked up off the ground, its brake is negated, and the car more
likely to roll. Chocking the wheel
(ie, putting one block under the front of the tire and one block under the
back of the tire) that is diagonally opposite (catty corner) to the wheel
being jacked up will enhance safety.
If you are not a person of great
strength, put a cheater bar in the trunk.
Cars come with a tire changing kit, which includes a car jack and a
lug wrench, but most lug wrenches are too short to allow a small person to
get enough leverage to loosen a lug nut that some tire mechanic tightened
with an air wrench. A cheater bar
is a length of metal pipe that you can slide over the lug wrench handle,
effectively making the lug wrench two or three times longer. A Mazda Miata comes with a one foot long lug
wrench. The wheel lug nuts are
supposed to be tightened to 90 lb feet of torque. That means that you have to exert over
90 lb of force on the end of that wrench in order to loosen the lug nut,
and you have to do it four times, once for each lug nut. If you slide a two foot long cheater bar
over the wrench, the force that you have to apply on the end of the bar
will be only 45 lb, a much more feasible force for a small person, and
since we are talking about a Miata, most large persons are not going to
fit into that car in the first place.
Now consider a soccer mom trying to change a tire on a
Suburban. Scary, huh? In that case, $112 per year for an AAA
(American Automobile Association) membership might sound like a reasonable
cost.
If you get locking wheels or wheel
covers on your car, keep the key to the lock in the car.
