What Is The Ideal Ford Focus Tire Pressure? [The Importance And Pros Of Proper Tire Inflation]

Last Updated on September 10, 2022 by John K. Clifford

The most important thing to care for your tires and enhance fuel efficiency is maintaining proper tire pressure. You could be wondering what the Ford Focus tire pressure is? 

The tire pressure for Ford Focus lies between 32psi to 46psi, as indicated by the manufacturer. It depends on the model’s original tire size and the gross vehicle weight rating (GVWR) to enhance vehicle safety, performance, and fuel economy. 

Checking the tire pressure in your Ford Focus is easy and crucial to do regularly. Open the driver-side door on your car and find the sticker that shows the tire pressure. Don’t use the maximum pressure displayed on the sidewall of your tires. It is important to ascertain the tire pressure on your Focus in the morning before being driven or when you have driven it for less than a mile. 

When you drive your Focus, the air inside the tires gets heated and expands, so to get the appropriate reading, check the pressure when the car has not been driven recently.

Establishing Proper Tire Pressure

Establishing Proper Tire Pressure

Check your vehicle manufacturer’s manual or the tire specification label on the driver’s side door frame. For older models, before 2003, you may find the tire inflation specification inside the glove box’s door, trunk lid, or fuel filler flap. Do not utilize the pressure found in the tire sidewall. This shows the force required to fill the tire’s full-rated load-carrying capacity, but not your vehicle’s tire pressure 

Automakers specify car tire pressure that may differ from front to rear and when the car is fully packed or used for a prolonged highway activity. The higher the pressure, the more the load capacity and reduced heat buildup. The table below shows recommended pressure for the 2018 Ford Focus:

What Is ‘Original Equipment’ Tire?

Original Equipment tire (OE) is the tire originally put in your car at the factory. While selecting these tires, the automakers collude with tire manufacturers to identify or develop tires that suit the characteristics and purposes of your car. For example, the manufacturer will choose a tire with a luxurious and quiet ride for a luxury vehicle. 

For a hybrid, they will select an eco-friendly low rolling resistance tire. They will select a tire with better handling and general performance for a sports car. In some instances, tires manufacturers develop and test customized versions of their tires or launch new tires to meet applications of a particular OE. 

Several OE tires are available for a particular vehicle; for instance, if you are driving a 2013 Honda Accord Sedan, depending on the style you drive, it could be fixed with a range of tires from different brands.

What Is The Importance Of Proper Tire Inflation?

Importance Of Proper Tire Inflation

Keeping your tire inflated at the recommended pressure by the manufacturer is vital to the maintenance of your vehicle and tires. If you don’t follow the recommended instructions, you may get various risks. Low tire pressure influences braking distances and becomes unresponsive during steering and handling. 

This can be particularly risky when an emergency brake is needed or during a sudden evasive move to avoid a collision. Also, low pressure causes the tire sidewalls to bend too much, releasing heat. While moderate heat increases tire tread wear, excessive heat can lead to loss of tread segments and blowouts. 

Under-inflated tires have better-rolling resistance, which minimizes fuel economy. They also wear quickly at the edges of the tread, which means you need to replace them sooner than with properly inflated tires. 

Overly inflated tires have not many problems. Modern tires can work well with pressures that exceed those recommended for usual driving. Nevertheless, frequently overinflated tires offer a less compliant ride and experience more rapid wear in the center of the tread, indicating that you should do replacement sooner than properly inflated tires. 

What are the Pros of Original Equipment Tires?

After using your car, you will inevitably need to replace your Original Equipment tires after some time. They can last up to 50,000 miles but begin to wear at 30,000 miles. Despite the apparent lack of durability from these tires, there is not a good reason why you should dish out your cash for their high-quality tires. Depending on the brand, a modified set of tires will improve your car’s handling traction and promote safety. However, for car enthusiasts, buying a replacement set of Original Equipment tires could give the following advantages:

  1. They Are Good at Everything

Before being shipped off, Original Equipment tires have to go through various tests. The tests have to prove that the tires can drive through different conditions such as cold, snow, dry road, gravel, and pavement.

 These tires could therefore be regarded as a jack of all trades. If you are a driver who needs your tires to take you from one point to another and perform well in various conditions, then OE tires are appropriate for you.

  1. They Are Designed Purposely for Your Car

These tires were not just picked at the back of a warehouse and fixed in your new car. In addition, OE tires are not similar across the board; they can also differ among a particular brand’s different styles or trims. 

The automakers mainly made the tires to meet your specific car’s features. For instance, a Hybrid’s OE tires are remarkably different from Jeep’s EO tires. Manufacturers chose these tires to maximize your car’s performance. Otherwise, you might find yourself disappointed with aftermarket replacement tires, especially if the design doesn’t suit your vehicle.

Why Does the Tire Pressure Light Turn On in My Ford Focus?

1. Change Of Temperature Outside

If you reside in an area characterized by a cold climate, keep tire temperature outside the house in the morning. When the temperature is higher, this could lead to excessive air entering the tire for driving throughout the day. 

This explains why the temperature light turns on when the outside temperature declines. Because air density fluctuates according to temperature, the tire pressure warning may turn on since it is affected by cooler temperatures.

2. Recent Change Of Rotation Of The Tire

If the tire position is altered, the tire sensors may need resetting. This may mean you should drive around for some minutes to allow the sensor to reset depending on the vehicle. If this doesn’t work, you may need to visit a dealership for proper calibration.

3. Damaged TPMS Sensors

The sensors on the TPMS may become damaged as time goes by because of the car’s travels over tough bumps or during tire servicing. Over time, the onboard battery also gets damaged. It might get damaged if the physical tire is ruined or filled with anything apart from air or nitrogen.

4. Faulty Wheel Speed Sensors

The wheel speed sensors on the TPMS Indirect system may get spoiled hence sending the wrong signal.

5. Low Pressure In Spare Tire

If the tire pressure warning light begins to illuminate the moment you use the spare tire, it indicates it also has low pressure.

What If The Light Is Still On After Adding Air To My Ford Focus Tire?

The first thing to do is use a tire pressure gauge to get a second reading to ensure the air pressure is appropriate. If the light on the dashboard remains on for long, it means one or more of the tires are leaking air. If the light brinks on for one second then off for three seconds severally, this shows the car has problems with one or more of the sensors. Contact the dealer immediately for service.
