Do Spare Tires Have TPMS?
The Tire Pressure Monitoring System (TPMS) has become a standard feature in modern vehicles. It is designed to monitor the air pressure in each of the tires and alert drivers if any tire becomes significantly underinflated. TPMS plays a crucial role in ensuring the safety and efficiency of a vehicle’s tires. However, when it comes to spare tires, the question arises – do spare tires have TPMS? In this article, we will delve into this topic and explore whether spare tires come equipped with TPMS or not.
Before we discuss whether spare tires have TPMS, it’s important to understand how TPMS functions. TPMS uses sensors to monitor the air pressure in each tire. These sensors are typically attached to the valve stem or incorporated within the tire itself. They continuously transmit data to the vehicle’s onboard computer, which analyzes the information and alerts the driver if any tire’s pressure falls below a specified threshold.
Types of TPMS
There are two types of TPMS – indirect TPMS and direct TPMS. Indirect TPMS relies on the vehicle’s Anti-lock Braking System (ABS) to monitor the rotational speed of the tires. If one tire starts rotating at a different speed due to low pressure, it detects the difference and triggers a warning light on the dashboard. On the other hand, direct TPMS uses sensors to measure the actual air pressure within each tire and sends the information to the vehicle’s computer.
1. Do Spare Tires Have Indirect TPMS?
Indirect TPMS systems typically do not include spare tires in their monitoring. The reason behind this is that spare tires are often different from regular tires in terms of their size, inflation pressure, and usage. Therefore, it becomes difficult for an indirect TPMS to accurately monitor the spare tire. As a result, if you have an indirect TPMS in your vehicle, it is unlikely that your spare tire will be equipped with TPMS.
2. Do Spare Tires Have Direct TPMS?
Direct TPMS, on the other hand, can potentially include the spare tire in its monitoring. Some vehicles with direct TPMS incorporate a sensor within the spare tire or have a separate sensor that can be installed on the spare tire. This allows the onboard computer to monitor the air pressure in the spare tire along with the regular tires. However, it is important to note that not all vehicles with direct TPMS have a sensor in the spare tire.
Importance of Monitoring Spare Tire Pressure
Now that we understand the types of TPMS and their potential inclusion of spare tires, let’s discuss the importance of monitoring spare tire pressure.
1. Emergency Situations
Spare tires are typically used in emergency situations such as a tire puncture or a blowout. In these situations, the last thing you would want is for your spare tire to be underinflated. Properly inflated tires ensure safe and reliable driving, especially during emergencies when you need to rely on your spare tire to get you to a safe place or to a tire repair shop. TPMS in the spare tire can provide the driver with confidence in the spare tire’s readiness to be used.
2. Long-Term Storage
If you have a spare tire that is not in use for an extended period, such as a full-sized spare or a spare tire in a truck bed, monitoring the air pressure becomes essential. Over time, normal changes in temperature and humidity can cause air to slowly escape from the tire. Additionally, spare tires can be prone to issues like dry rot or sidewall cracking if not properly maintained. By having TPMS in the spare tire, you can easily keep track of its air pressure without having to physically check it for potential issues.
What to Do If Your Spare Tire Doesn’t Have TPMS
If your vehicle does not have TPMS in the spare tire, there are a few steps you can take to ensure the safety and effectiveness of your spare tire.
1. Regular Inspection
Regularly inspect the spare tire to ensure it is in good condition. Check for any visible damage, including cuts, punctures, or sidewall damage. Additionally, check the tread depth to ensure it meets the minimum requirements. While inspecting the spare tire, it is also a good idea to check the air pressure using a tire pressure gauge.
2. Maintain Proper Inflation
Even if your spare tire doesn’t have TPMS, it is important to maintain proper inflation. Underinflated spare tires can result in poor handling, reduced fuel efficiency, and increased risk of a blowout. Refer to the owner’s manual or the information label on your vehicle’s door jamb for the recommended tire pressure for your spare tire. Regularly check the air pressure and inflate the spare tire as necessary.
3. Get Professional Tire Service
If you are unsure about the condition or inflation of your spare tire, it is always best to consult a professional tire service center. They can inspect the spare tire and provide recommendations for inflation, repairs, or replacements if needed. Professional tire technicians have the necessary expertise to ensure your spare tire is in optimal condition and ready for use when needed.
In conclusion, whether spare tires have TPMS depends on the type of TPMS system in your vehicle. Indirect TPMS systems typically do not include spare tires, while direct TPMS systems have the potential to monitor the spare tire. Regardless of whether your spare tire has TPMS or not, it is important to regularly inspect and maintain proper inflation to ensure its reliability and effectiveness in emergency situations. If you are unsure about the condition of your spare tire, consult a professional tire service center for expert advice.
