Just a Reminder

Spring is here. That means it's time to rotate the air in your tires.
You need to pump the air out of your front tires and put that same air
back in your rear tires. However if your air is more than three years
old, it's recommended to replace it with new air. However, if you live
in a northern climate, your car probably has Winter Air in the tires.
This must be completely removed, and replaced with Summer Air, before
the hot weather arrives.

This is not something you can do at home, without specialized equipment.
Get it done professionally, so it's done right, which insures that
you're tires are safe. After all, your life depends on those tires.

Prices vary according to where you live, but I've seen Air Rotation for
as little as $5.99. If you're getting the air replaced, or need Summer
Air, the cost is quite a bit more. Shop around, and watch the newspaper
for specials and coupons. Some places will rotate your air for free, if
you have them change your oil and/or get a tuneup.

While you're at it, have your coolant replaced with a 50-50 mix of
antifreeze (ethylene glycol) and an automotive-grade solvent (e.g.
"dyhydrogen monoxide" aka "DHMO").

Be careful though, DHMO is nasty stuff:
