tire pressure

I have a checklist I use before each trip.  Stuff to pack, things to turn off around the house, things to check on the TV and 'pod.  Checking lug nut torque and tire pressure on the 'pod is one item on that list.  So far I've had little to no adjustment necessary on the 'pod but other trailers and campers I've owned needed something every time.

How much air should I put in my tires?

Proper inflation is the single most important part of tire care. The inflation pressure on the side of the tire is the MAXIMUM operating pressure. It is not necessarily the right inflation for your vehicle. Always use the inflation recommended by the vehicle manufacturer. You can find it in your owner's manual, posted on the edge of the driver's door, on a door post or on the inside of the glovebox door. Always check inflation when tires are COLD: when the vehicle has been driven less than a mile or one hour or more after driving. Use a good quality tire gauge. Note: It's natural for radial tires to have a slight bulge in the sidewall at their proper inflation pressure. Check or adjust inflation every few weeks, before any long trip or if traveling with a heavy load. And don't forget to check the spare. Your Goodyear retailer can answer any questions you may have about tire inflation.
