Not Suitable for Cold Weather: Summer tyres tend to harden in low temperatures, leading to reduced performance and grip on wet or icy roads.
Winter Tyres
Winter tyres, also known as snow tyres, are specifically engineered to tackle harsh winter conditions, including snow, ice, and freezing temperatures. They offer superior performance in cold weather and provide enhanced safety during winter driving. Notable features of winter tyres include the following.
Winter-Optimised Rubber Compound: Winter tyres use a softer rubber compound that remains flexible in cold temperatures, ensuring excellent grip on snow and ice.
Deep Tread Patterns: The deep grooves and biting edges of winter tyres improve traction in snowy and icy conditions, preventing skidding and enhancing stability.
Mandatory in Some Regions: In areas with severe winters, some countries and regions legally require drivers to fit winter tyres during specific months to ensure safer road conditions.
Performance tyres, also known as sport tyres, are designed for enthusiastic drivers who prioritise high-speed handling and superior performance. These tyres are commonly used in sports cars and high-performance vehicles. Key characteristics of performance tyres include the following.
Enhanced Grip: Performance tyres use advanced rubber compounds and tread patterns to provide maximum grip and responsive handling, allowing for precise cornering and braking.
Reduced Tread Life: Due to the focus on performance, these tyres generally have a softer rubber composition, which leads to a shorter tread life compared to regular tyres.
Limited Wet Weather Performance: While performance tyres excel in dry conditions, they may not perform as well in wet weather, making them less suitable for regions with heavy rainfall.
Run-Flat Tyres
Run-flat tyres are specially designed to allow continued driving for a limited distance after a puncture or loss of air pressure. They are equipped with reinforced sidewalls that support the weight of the vehicle even when deflated. Notable features of run-flat tyres include the following.
Extended Mobility: Run-flat tyres enable drivers to continue driving at a reduced speed to reach a service station or a safe location after a puncture.
No Spare Tyre Needed: With run-flat tyres, drivers don't need to carry a spare tyre, reducing the overall weight of the vehicle and freeing up storage space.
Limited Repairability: Once a run-flat tyre has been driven on while flat, it may not be repairable, and replacement may be necessary.
All-Terrain Tyres
All-terrain tyres are the jack-of-all-trades in the world of off-road driving. They strike a balance between on-road comfort and off-road performance, making them a popular choice for versatile 4x4 vehicles. Key features of all-terrain tyres include the following.
Robust Construction: All-terrain tyres are built with reinforced sidewalls and durable materials to withstand rough and rocky terrains.
Tread Design: Their tread pattern features larger tread blocks with deeper voids, providing improved traction on mud, gravel, sand, and rocky surfaces.
On-Road Capability: All-terrain tyres maintain decent on-road performance, offering a smooth and quiet ride for everyday driving.
Mud-Terrain Tyres
Mud-terrain tyres are purpose-built for tackling deep mud, slippery surfaces, and challenging off-road conditions. They are the go-to choice for extreme off-road enthusiasts and those who frequently encounter muddy terrains. Notable characteristics of mud-terrain tyres include the following.
Aggressive Tread Pattern: Mud-terrain tyres have large, chunky tread blocks with wide voids to self-clean, expelling mud and debris for sustained traction.
Deep Grooves: These tyres feature deep channels, known as "lugs," which provide enhanced grip in thick mud and slushy terrains.
Sacrificed On-Road Comfort: Due to their aggressive design, mud-terrain tyres may produce more noise and offer a stiffer ride on regular roads.
Emergency Spare Tyres
Emergency spare tyres are a type of temporary tyre provided by vehicle manufacturers, usually found in the boot of new cars. They serve as a backup solution in case of a flat tyre or puncture. Notable characteristics of emergency spare tyres include the following.
Match OEM Tyres: Emergency spare tyres are designed to match the original equipment manufacturer (OEM) tyres in size and specifications.
Limited Mileage: Like space-saver tyres, emergency spares are meant for short distances and should not be driven for extended periods.
Replace Promptly: If you use an emergency spare tyre, it's essential to replace it with a regular tyre as soon as possible to restore full functionality and safety to your vehicle.
Space-Saver Tyres
Space-saver tyres, as the name suggests, are designed to save space in your vehicle while serving as a temporary replacement for a flat tyre. They are smaller and narrower than regular tyres, making them easier to store in the boot or under the vehicle's luggage area. Key features of space-saver tyres include the following.
Compact Size: Space-saver tyres are smaller and lighter than regular tyres, allowing them to fit conveniently in the limited storage space of your vehicle.
Reduced Speed and Mileage: These tyres are intended for short-distance driving at lower speeds, typically limited to around 50 mph for a limited distance.
Temporary Use Only: Space-saver tyres are not meant for prolonged use and are designed solely as an emergency solution to get you to a service station or a safer location.
Choosing the Right Tyre for Your Car
Selecting the right tyres for your car is crucial. It depends on your driving habits, local weather conditions, and vehicle specifications. Following are some factors to consider when making your decision.
Tyre Size
The first step in choosing the right tyre is to check the manufacturer's recommended tyre size for your car. This information is usually found in the owner's manual or on a label inside the driver's door. The tyre size is denoted by a combination of numbers and letters, such as 205/55R16. It indicates the tyre's width, aspect ratio, and rim diameter.
Tyre Tread
The tread pattern plays a crucial role in determining a tyre's performance in various weather conditions. Different tread patterns are designed to excel in specific conditions. Following are more details on the same.
Symmetrical Tread: Offers a smooth and quiet ride, suitable for everyday driving in normal weather conditions.
Asymmetrical Tread: Provides a balance of performance on wet and dry roads, with different inner and outer tread patterns.
Directional Tread: Optimised for wet conditions, with a V-shaped pattern to channel water away from the tyre.
