Many car owners overlook the importance of selecting the correct tyres for their vehicles, unaware of the significant impact it has on performance, safety, and long-term costs. The right tyres are essential for optimal handling, fuel efficiency, and braking performance. At Moreleta Service Centre, we’ve witnessed firsthand how incorrect tyre choices lead to costly repairs, poor fuel economy, and increased accident risks.

Understanding Tyre Specifications

Every tyre has key markings on its sidewall that indicate crucial specifications such as size, load index, and speed rating. Understanding these details ensures that you choose tyres suited to your vehicle’s requirements:

• Tyre width – The first number on the sidewall, measured in millimetres, represents how wide the tyre is.
• Aspect ratio – A percentage indicating the tyre’s height relative to its width.
• Diameter – Measured in inches, this determines the wheel size the tyre fits.
• Load index – Shows the maximum weight a tyre can carry safely.
• Speed rating – A letter indicating the maximum speed the tyre can sustain under safe conditions.

Fitting tyres that do not align with these specifications can result in instability, excessive wear, and higher operational costs.

Why Load Index and Speed Rating Matter

Car manufacturers specify the ideal load index and speed rating to maintain safety and performance. Ignoring these factors can cause:

• Excessive tyre wear – Tyres not rated for your vehicle’s weight deteriorate faster, leading to frequent replacements.
• Reduced fuel efficiency – Incorrect tyres increase rolling resistance, making your engine work harder and burn more fuel.
• Compromised braking – Tyres with an incorrect speed rating may not respond effectively in emergencies.
• Handling issues – A lower-than-required load index and speed rating can result in poor stability, especially when carrying heavy loads or driving at high speeds.

Special Considerations: Off-Roading and Heavy Loads

If your vehicle is regularly used for off-roading or transporting heavy loads, standard tyres may not be suitable. Specialised tyres, such as all-terrain or heavy-duty options, are designed to handle specific conditions:

• All-terrain and off-road tyres – Built for rough terrain with a higher load index but lower speed rating.
• Heavy-duty tyres – Essential for transporting heavy goods or equipment, ensuring durability under pressure.
• Inflation adjustments – Tyres with a higher load index may require different inflation pressures to maintain performance and safety.

Ensuring that your vehicle is fitted with the correct tyres improves safety, enhances performance, and prevents unnecessary repair costs. Moreleta Service Centre provides expert tyre advice, helping customers select tyres that meet their vehicle’s exact specifications.
