Tire Pressure

Phantom Tire Buyer with a Secret Identity

Dear Diary,

It is hot.  My Phantom Lair is located in a top-secret location in Cincinnati, Ohio.  And like many of our friends in the Midwest, we are experiencing a massive heatwave.  I am trying to stay inside whenever possible.  BUT – as a Phantom Tire Buyer, I have responsibilities that only grow more crucial with every uptick of the thermometer. 

We can all agree that proper tire pressure is essential to maintaining safe and long-lasting tires.  But did you know that extreme heat makes tire pressure even more CRUCIAL?  My neighbors all know it. Recently my monthly neighborhood complimentary tire pressure check became a weekly neighborhood pressure check. I begin my rounds before dawn, allowing me to be finished before the real heat of the day sets in. After all, we all know tire pressure is best checked first thing in the morning.

While intense heat can increase the pressure in your tires, creating a potential danger of lack of control and even tire failure, many people don’t understand that the ill effects of underinflated tires are exaggerated in the heat.  Under-inflation can warp the sidewall and create more heat in the rubber, which affects handling and tire wear.

Just a side note to those of you who may want to volunteer to become your neighborhood’s complimentary tire pressure checker…you might want to get everyone’s permission first.  I won’t go into the details, but you don’t want to be standing in your neighbor’s driveway with a flashlight in one hand and a tire pressure gauge in the other when a police cruiser pulls up. It may be better to just visit your neighborhood Tire Discounters location for your own free tire pressure check and safety inspection.

The speed rating of a tire is based on U.S. Government standards for reaching and sustaining a specified speed. Typically, a tire with a higher speed rating results in better handling. Speed ratings apply only to the tire itself, and not to a particular vehicle. Putting a tire rated for a certain speed on a vehicle does not mean that the vehicle can be safely operated at the tire's rated speed.

The load range on a tire helps determine its ability to contain air pressure and its overall strength. Ranges are expressed using a number and the higher the number, the stronger the tire. These measurements are primarily for light trucks and SUV’s.

Tread depth is the distance between the top of the tread rubber to the bottom of the tire's deepest grooves.  In the United States, tread depth is measured in 32nds of an inch.

A tire’s maximum load is the maximum amount of weight the tire is designed to hold. The tire’s load carrying capacity is directly related to the tire’s size and amount of inflation pressure that is actually used. Each load range has a assigned air pressure identified in pounds per square inch (psi) at which the tire's maximum load is rated.

The total width of the tire, including any raised features on the sidewall. 

This is how many layers of rubber and other materials are in the tire.  

The measurement, in inches, from rim flange to the other rim flange. 

The maximum width of a wheel that a tire can be put onto. 

The minimum width of a wheel that a tire can be put onto.  

A tire's section width (also called "cross section width") is the measurement of the tire's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. 

What makes up a tire; each ply, the sidewall, the tread, and bead.  

This number will tell you how well the tire will disperse heat buildup. 

This is how much weight a tire is rated to hold.

A tire’s maximum inflation pressure (PSI) is the highest "cold" inflation pressure that the tire is designed to contain. When measuring a tire’s max PSI, it is important the tire is "cold," because warmer temperatures can cause the tire pressure to temporarily increase resulting with inaccurate readings. This measurement should only be used when called for on the vehicle’s tire placard or in the vehicle’s owners manual.

The mileage warranty of a tire indicates the number of miles that a tire is estimated to last. If a tire fails to last for the number of miles indicated by the warranty, the customer will be given credit from the tire manufacturer toward a new tire based on how many miles short of the estimate the tire fell. Some restrictions apply.

Components of the Tire Pressure Monitoring System (TPMS) sensor wears over time.

A TPMS Service Kit is suggested each time a tire/wheel is serviced. If left unchanged, over time, these components of the TPMS may corrode, leak or fail.

Tire/wheel service is defined as when tire is removed from the wheel.

The represents the smallest and widest size wheels that are recommended by the tire manufacturer for the tire to be mounted on.
