NOTICE:

It's time to change the air in your tires. Well, actually this should
have been done around December 20th when Winter officially began. But
if you did not do it then, DO IT NOW.
It's time to insure that your tires contain WINTER AIR.

Go to any established tire center.

They should have four air compressors containing each of the following
labels.

Winter air
Spring air
Summer air
Fall air

Use the one to match the season, which is now WINTER AIR.....

Dont forget to change the air in your tires every season.

It is more complicated than that. We now have metric air also.
