"Low profile" tyres refer to tyres with a shorter sidewall height, also known as the aspect ratio. The aspect ratio is the measurement of the tyre's sidewall from the edge of the wheel or rim to the road surface. Low profile tyres typically feature larger tread blocks, a stiffer and wider apex, and may be made from specialised rubber compounds, making them distinct from standard tyres. While they are often associated with sports cars and performance vehicles, low profile tyres are becoming increasingly popular on a wider range of vehicles. But are they the right choice for you?
What Are Low Profile Tyres?
The most noticeable characteristic of low profile tyres is their reduced sidewall height compared to standard tyres. Typically, the sidewall is shorter, which means there’s less rubber between the rim and the road. These tyres are often paired with larger wheels to maintain the overall diameter of the tyre and wheel combination, which is crucial for the vehicle’s performance and handling.
Low profile tyres are often fitted to enhance the aesthetic appeal of a vehicle, but they also provide tangible benefits in terms of handling, braking, and steering responsiveness. However, they also come with some drawbacks that drivers should consider before upgrading.
Advantages of Low Profile Tyres
1. Improved Handling and Responsiveness
One of the main reasons drivers opt for low profile tyres is the improved handling and responsiveness they offer. The wider footprint of these tyres provides better grip on the road, especially during high-speed cornering. The stiffer sidewalls help in reducing body roll, allowing for more precise and responsive steering. This makes low profile tyres a popular choice for performance driving and sports cars.
With larger rims, which often accompany low profile tyres, drivers also benefit from larger brakes. This can significantly improve braking performance, allowing the vehicle to stop more quickly, which is a crucial safety advantage in high-performance driving situations.
2. Aesthetics
There’s no denying that low profile tyres can dramatically improve the look of a vehicle. The sleek and aggressive appearance of low profile tyres, paired with larger alloy wheels, gives the vehicle a more modern and sporty look. For many car enthusiasts, the visual appeal is a major factor in opting for low profile tyres, as they give the vehicle a more dynamic and customised appearance.
3. Better Traction in Certain Conditions
Due to the wider tread of low profile tyres, they can provide improved traction on dry roads, especially during spirited driving or high-speed manoeuvres. The larger contact patch with the road improves stability and reduces skidding, making them ideal for driving enthusiasts who prioritise grip and control.
Disadvantages of Low Profile Tyres
Despite their performance benefits, low profile tyres are not without drawbacks. Here are some factors to consider before making the switch.
1. Rougher Ride Quality
One of the most noticeable disadvantages of low profile tyres is the reduced ride comfort. The shorter sidewalls mean that there is less rubber to absorb shocks and vibrations from the road. This results in a firmer and rougher ride, especially on uneven or poorly maintained road surfaces. Drivers may feel more of the bumps, potholes, and irregularities in the road compared to when using traditional tyres with taller sidewalls.
2. Increased Risk of Damage
Because there’s less rubber protecting the rims, low profile tyres are more susceptible to damage from potholes, kerbs, and other road hazards. The thinner sidewalls are more prone to punctures, and the rims themselves are at a higher risk of being scratched or bent, especially on rough or uneven roads. Drivers should be cautious when navigating through road debris or poorly maintained streets.
3. Higher Costs
Upgrading to low profile tyres and larger wheels can be more expensive than sticking with traditional tyres. Low profile tyres are generally made from specialised materials and offer performance benefits, which often come at a higher price point. Additionally, the larger wheels that typically accompany low profile tyres can also increase the overall cost of the upgrade.
4. Potential for Reduced Stability
While low profile tyres can improve handling and steering response, they may also reduce overall vehicle stability if the car was not originally designed for such tyres. Some vehicles may experience instability or handling issues if they are fitted with low profile tyres without appropriate adjustments to the suspension or other components. It’s essential to ensure that your vehicle can safely accommodate these tyres before making the switch.
Things to Consider When Buying Low Profile Tyres
1. Upgrade as a Full Set
It’s important to note that when upgrading to low profile tyres, you should always install a full set on your vehicle. Mixing low profile tyres with standard tyres on the same car can lead to handling imbalances and safety issues. Ensure that all four tyres match in terms of size, aspect ratio, and tread design for optimal performance.
2. Get Professional Installation
Due to the unique characteristics of low profile tyres, it’s critical to have them fitted by a professional mechanic. Improper installation can lead to alignment issues or even damage to the tyres or rims. Professionals will ensure that the tyres are correctly balanced and installed, helping you get the best performance out of your new tyres.
3. Check Compatibility with Your Vehicle
Before deciding on low profile tyres, check with your vehicle manufacturer or a qualified mechanic to confirm that your car can safely accommodate the upgrade. If your vehicle’s suspension or brake system wasn’t designed for low profile tyres, additional modifications may be required to ensure safe driving.
4. Improved Cornering and Stability on Dry Roads
Low profile tyres can improve cornering performance, especially on dry, smooth surfaces. The stiffer sidewalls and wider tread pattern reduce the flex in the tyre during cornering, providing more stable handling at higher speeds. This makes them particularly effective in sports cars or vehicles where performance driving is a priority.
5. Handling in Wet Conditions
While low profile tyres offer better handling on dry roads, they may not perform as well in wet or icy conditions compared to tyres with deeper tread patterns. The wide tread of low profile tyres can struggle to displace water as efficiently, increasing the risk of aquaplaning. This is especially important to consider if you live in an area that experiences a lot of rainfall or icy conditions.
6. Road Noise
Low profile tyres often result in increased road noise, particularly on rough or textured surfaces. The stiffer sidewalls and larger wheels tend to transmit more vibration and noise into the cabin, making for a louder ride. If a quiet cabin is important to you, consider how low profile tyres might affect your driving experience, especially on highways or long-distance drives.
7. Tyre Pressure Sensitivity
Low profile tyres are typically more sensitive to tyre pressure, which can directly affect their performance and lifespan. Because of their lower sidewall height, even a slight reduction in pressure can lead to tyre damage or poor handling. Regular tyre pressure checks are critical when using low profile tyres to ensure optimal performance and to avoid unnecessary wear and tear.
8. Suspension and Ride Comfort
If you’re upgrading to low profile tyres, you may also need to consider adjusting or upgrading your suspension system. Low profile tyres can sometimes affect the overall balance and comfort of your vehicle, particularly in vehicles that were not designed with these tyres in mind. A suspension upgrade can help mitigate the harsher ride and ensure that your vehicle handles well with the new tyres.
9. Fuel Efficiency
While low profile tyres can improve handling and braking, they may also lead to a slight decrease in fuel efficiency due to the increased rolling resistance caused by the larger contact area with the road. This is something to keep in mind if you’re looking to maximise fuel economy, as other types of tyres may offer better fuel-saving performance.
10. Tyre Maintenance
Low profile tyres typically wear out faster than traditional tyres due to their design and the stresses placed on them during high-performance driving. It’s essential to conduct regular inspections for signs of wear, such as uneven tread or bulges in the sidewall, and ensure that you rotate them regularly to extend their lifespan.
Choosing the Right Size for Low Profile Tyres
When upgrading to low profile tyres, it’s important to choose the correct size to maintain the overall diameter of the tyre and wheel combination. Changing the diameter too much can affect your vehicle’s speedometer, ABS system, and overall ride quality. Work with a professional to ensure you’re selecting the right size for your vehicle to avoid any negative impact on performance.
Legal and Insurance Implications
In some regions, changing to low profile tyres may require notifying your insurance company or even seeking approval from the relevant WA department of transport. Modifications to your vehicle that affect its performance can sometimes influence insurance premiums, so it’s important to check with your provider to ensure your coverage remains valid after making the switch.
Conclusion: Are Low Profile Tyres the Right Choice for You?
