Can I Use a 245 Tire Instead of 235?
If you’re in the market for new tires and considering whether you can use a 245 tire instead of a 235, you’re not alone. Many car owners wonder if they can make this switch and if it would have any impact on their vehicle’s performance and safety. The quick answer is yes, you can use a 245 tire instead of a 235, but let’s dive deeper into the details to understand why and what factors you need to consider before making the switch.
Understanding Tire Sizes and How They Affect Performance
When it comes to tire sizes, there are a few important measurements to consider. The first number represents the tire’s width in millimeters, and the second number indicates the aspect ratio or the height of the sidewall as a percentage of the width. In this case, a 235 tire would be narrower than a 245 tire.
The main difference between using a 235 tire and a 245 tire lies in the width. By switching to a wider tire, you increase the contact patch with the road, which can offer improved traction and handling. However, there are several factors you need to keep in mind before making this change.
Fitment and Clearance
One crucial factor to consider is whether the wider 245 tire will fit properly on your vehicle. You need to ensure that there is enough clearance in the wheel well, suspension components, and the fender. If the tire rubs against any part of your vehicle when turning or going over bumps, it can cause damage and negatively impact your driving experience.
It’s also important to note that different vehicles have different recommended tire sizes. This information can typically be found in your vehicle’s owner’s manual or on the tire placard located inside the driver’s side door jamb. Deviating from the recommended tire size may affect your vehicle’s speedometer accuracy and overall performance.
Speedometer Accuracy
Switching from a 235 tire to a 245 tire may slightly affect your vehicle’s speedometer accuracy. Since the 245 tire has a larger circumference, it travels slightly farther in one revolution compared to the 235 tire. This difference in circumference can lead to a slightly higher speedometer reading than your actual speed.
While the difference may be minimal, it’s important to take into consideration, especially if you frequently rely on your vehicle’s speedometer for navigation or are concerned about potential speeding tickets. To maintain accuracy, you can recalibrate your speedometer or use a GPS device for more precise speed readings.
Fuel Efficiency and Ride Comfort
It’s worth noting that switching to a wider 245 tire may have a slight impact on fuel efficiency. The wider contact patch can increase rolling resistance, which may result in a small decrease in fuel economy. However, the difference in fuel consumption is usually negligible unless you’re making significant changes in tire size.
Additionally, a wider tire can also provide a slightly firmer ride as it absorbs less of the irregularities on the road surface. This can translate to a slightly harsher feeling when going over bumps or road imperfections. If ride comfort is a top priority for you, it’s essential to consider this aspect before switching to a wider tire.
Tire Load Capacity and Handling
Every tire has a designated load capacity, which is the maximum weight it can safely carry. Generally, wider tires have a higher load capacity compared to narrower ones. However, it’s crucial to ensure that the load capacity of the 245 tire you are considering is compatible with your vehicle. Exceeding the tire’s load capacity can lead to premature tire wear, decreased handling, and potential safety hazards.
Furthermore, changing the tire’s width can have a slight impact on the vehicle’s handling characteristics. Wider tires can provide more grip and stability, which can be beneficial in certain driving conditions. However, they can also affect the vehicle’s responsiveness and steering feel. It’s important to consider your driving preferences and the intended use of your vehicle before making the switch.
Frequently Asked Questions

Will using a wider tire affect my vehicle’s speedometer accuracy?
Yes, switching to a wider tire can result in a slightly higher speedometer reading than your actual speed. Consider recalibrating your speedometer or using a GPS device for more accurate readings.
What is the recommended tire size for my vehicle?
You can typically find the recommended tire size for your vehicle in the owner’s manual or on the tire placard located inside the driver’s side door jamb.
Final Thoughts
When it comes to using a 245 tire instead of a 235, it’s important to consider several factors such as fitment, speedometer accuracy, fuel efficiency, ride comfort, and handling. While the switch may offer improved traction and handling, it’s crucial to ensure that the wider tire fits properly on your vehicle and does not negatively impact its performance.
Always consult your vehicle’s owner’s manual or seek professional advice if you’re unsure about making this change. By considering these factors and understanding the potential implications, you can make an informed decision that best suits your driving needs and preferences.
