Study Notes
Tyre
Types of Tyres
- Radial Tyres: Most common type, with cords running perpendicular to the direction of travel.
- Bias Tyres: Cords run at an angle, less common due to lower performance and durability.
- Diagonal Tyres: Combination of radial and bias construction, rare in modern vehicles.
Tyre Components
- Tread: Outer layer, provides traction and grip.
- Sidewall: Middle layer, provides flexibility and protection.
- Carcass: Inner layer, consists of cords and rubber.
- Bead: Inner rim, where the tyre meets the wheel.
- Ply: Layers of rubber and cords, affects tyre strength and durability.
Tyre Performance Factors
- Tread Depth: Affects traction and braking performance, minimum 1.6mm for safe operation.
- Tyre Pressure: Affects fuel efficiency, handling, and tyre wear, recommended pressure varies by vehicle.
- Tyre Temperature: Affects tyre performance and durability, excessive heat can lead to blowouts.
- Load Rating: Maximum weight capacity, affects tyre strength and durability.
Tyre Maintenance and Inspection
- Tyre Pressure Check: Regular checks to ensure proper pressure.
- Tread Depth Check: Regular checks to ensure minimum tread depth.
- Visual Inspection: Check for signs of wear, damage, or uneven wear.
- Tyre Rotation: Regular rotation to ensure even wear and extend tyre life.
Tyre Safety and Regulations
- Tyre Safety Ratings: International standards for tyre performance and safety.
- Tyre Labelling: EU regulation requiring tyres to display fuel efficiency, wet grip, and noise ratings.
- Tyre Age: tyres older than 6 years may be unsafe, even if appearance is good.
Tyre Types
- Radial tyres are the most common type, with cords running perpendicular to the direction of travel.
- Bias tyres have cords running at an angle, are less common, and offer lower performance and durability.
- Diagonal tyres are a rare combination of radial and bias construction, mostly absent in modern vehicles.
Tyre Structure
- The tread is the outer layer, providing traction and grip.
- The sidewall is the middle layer, offering flexibility and protection.
- The carcass is the inner layer, consisting of cords and rubber.
- The bead is the inner rim, where the tyre meets the wheel.
- The ply refers to the layers of rubber and cords, affecting tyre strength and durability.
Tyre Performance
- Tread depth affects traction and braking performance, with a minimum of 1.6mm required for safe operation.
- Tyre pressure impacts fuel efficiency, handling, and tyre wear, with recommended pressures varying by vehicle.
- Tyre temperature affects tyre performance and durability, with excessive heat potentially leading to blowouts.
- Load rating is the maximum weight capacity, influencing tyre strength and durability.
Tyre Maintenance
- Regular tyre pressure checks ensure proper pressure.
- Regular tread depth checks ensure minimum tread depth.
- Visual inspections are necessary to detect signs of wear, damage, or uneven wear.
- Tyre rotation is essential for even wear and extended tyre life.
Tyre Safety and Regulations
- International tyre safety ratings ensure tyre performance and safety standards.
- EU tyre labelling regulations mandate the display of fuel efficiency, wet grip, and noise ratings.
- Tyres older than 6 years may be unsafe, even if they appear in good condition, due to tyre age.
