Tires, Wheels and Loading -> INFLATING YOUR TIRES for Your Ford Focus 4 Door Second Generation (2004-2010)

Tires, Wheels and Loading  
Extra load: A class of P-metric or Metric tires designed to carry a  
heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires].  
Increasing the inflation pressure beyond this pressure will not increase  
the tire’s load carrying capability.  
kPa: Kilopascal, a metric unit of air pressure.  
PSI: Pounds per square inch, a standard unit of air pressure.  
Cold inflation pressure: The tire pressure when the vehicle has  
been stationary and out of direct sunlight for an hour or more and  
prior to the vehicle being driven for 1 mile (1.6 km).  
Recommended inflation pressure: The cold inflation pressure found  
on the Safety Compliance Certification Label or Tire Label located on  
the B-Pillar or the edge of the driver’s door.  
B-pillar: The structural member at the side of the vehicle behind the  
front door.  
Bead area of the tire: Area of the tire next to the rim.  
Sidewall of the tire: Area between the bead area and the tread.  
Tread area of the tire: Area of the perimeter of the tire that  
contacts the road when mounted on the vehicle.  
Rim: The metal support (wheel) for a tire or a tire and tube assembly  
upon which the tire beads are seated.  
INFLATING YOUR TIRES  
Safe operation of your vehicle requires that your tires are properly  
inflated. Every day before you drive, check your tires. If one looks lower  
than the others, use a tire gauge to check pressure of all tires and adjust  
if required. Remember that a tire can lose up to half of its air pressure  
without appearing flat.  
At least once a month and before long trips, inspect each tire and check  
the tire pressure with a tire gauge (including spare, if equipped). Inflate  
all tires to the inflation pressure recommended by Ford Motor Company.  
Use a tire gauge to check the tire inflation pressure, including the spare  
(if equipped), at least monthly and before long trips. You are strongly  
urged to buy a reliable tire pressure gauge, as automatic service station  
gauges may be inaccurate. Ford Motor Company recommends the use of  
a digital or dial-type tire pressure gauge rather than a stick-type tire  
pressure gauge.  
Use the recommended cold inflation pressure for optimum tire  
performance and wear. Under-inflation or over-inflation may cause  
uneven treadwear patterns.

Under-inflation is the most common cause of tire failures and  
may result in severe tire cracking, tread separation or ЉblowoutЉ,  
with unexpected loss of vehicle control and increased risk of injury.  
Under-inflation increases sidewall flexing and rolling resistance,  
resulting in heat buildup and internal damage to the tire. It also may  
result in unnecessary tire stress, irregular wear, loss of vehicle control  
and accidents. A tire can lose up to half of its air pressure and not  
appear to be flat!  
Always inflate your tires to the Ford recommended inflation pressure  
even if it is less than the maximum inflation pressure information found  
on the tire. The Ford recommended tire inflation pressure is found on  
the Safety Compliance Certification Label or Tire Label which is located  
on the B-Pillar or the edge of the driver’s door. Failure to follow the tire  
pressure recommendations can cause uneven treadwear patterns and  
adversely affect the way your vehicle handles.  
Maximum Permissible Inflation Pressure is the tire manufacturer’s  
maximum permissible pressure and/or the pressure at which the  
maximum load can be carried by the tire. This pressure is normally  
higher than the manufacturer’s recommended cold inflation pressure  
which can be found on the Safety Compliance Certification Label or Tire  
Label which is located on the B-Pillar or the edge of the driver’s door.  
The cold inflation pressure should never be set lower than the  
recommended pressure on the Safety Compliance Certification Label or  
Tire Label.  
When weather temperature changes occur, tire inflation pressures also  
change. A 10° F (6° C) temperature drop can cause a corresponding  
drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures  
frequently and adjust them to the proper pressure which can be found  
on the Safety Compliance Certification Label or Tire Label.  
To check the pressure in your tire(s):  
1. Make sure the tires are cool, meaning they are not hot from driving  
even a mile.  
If you are checking tire pressure when the tire is hot, (i.e. driven more  
than 1 mile [1.6 km]), never “bleed” or reduce air pressure. The tires are  
hot from driving and it is normal for pressures to increase above  
recommended cold pressures. A hot tire at or below recommended cold  
inflation pressure could be significantly under-inflated.

Note: If you have to drive a distance to get air for your tire(s), check  
and record the tire pressure first and add the appropriate air pressure  
when you get to the pump. It is normal for tires to heat up and the air  
pressure inside to go up as you drive.  
2. Remove the cap from the valve on one tire, then firmly press the tire  
gauge onto the valve and measure the pressure with the tire gauge.  
3. Add enough air to reach the recommended air pressure.  
Note: If you overfill the tire, release air by pushing on the metal stem in  
the center of the valve. Then recheck the pressure with your tire gauge.  
4. Replace the valve cap.  
5. Repeat this procedure for each tire, including the spare.  
Note: Some spare tires operate at a higher inflation pressure than the  
other tires. For T-type/mini-spare tires (see T-Type/Mini-Spare Tire  
Information section for description): Store and maintain at 60 psi  
(4.15 bar). For Full Size and Dissimilar spare tires (see Dissimilar  
Spare Tire/Wheel Information section for description): Store and  
maintain at the higher of the front and rear inflation pressure as shown  
on the Safety Compliance Certification Label or the Tire Label.  
6. Visually inspect the tires to make sure there are no nails or other  
objects embedded that could poke a hole in the tire and cause an air  
leak.  
7. Check the sidewalls to make sure there are no gouges, cuts or bulges.  
TIRE CARE  
Inspecting your tires  
Periodically inspect the tire treads for uneven or excessive wear and  
remove objects such as stones, nails or glass that may be wedged in the  
tread grooves. Check for holes or cuts that may permit air leakage from  
the tire and make necessary repairs. Also inspect the tire sidewalls for  
cracking, cuts, bruises and other signs of damage or excessive wear. If  
internal damage to the tire is suspected, have the tire demounted and  
inspected in case it needs to be repaired or replaced. For your safety,  
tires that are damaged or show signs of excessive wear should not be  
used because they are more likely to blow out or fail.
