Tyre Ratings & Best Tyres for Road Use — With Real Vehicle Examples

1. Tyre Ratings: What to Look For These ratings appear on the tyre sidewall and help you judge quality, safety, and performance. Treadwear Rating This tells you how long a tyre is likely to last. The higher the number, the longer it should last. A treadwear of 400 means the tyre will last about 4 times longer than a baseline test tyre. Traction Rating This shows how well the tyre grips on wet roads. The grades are: AA (excellent), A (good), B (moderate), and C (poor). Temperature Rating This tells you how well the tyre resists heat. High heat resistance means the tyre won’t overheat and burst at high speeds. Grades: A (best), B, and C. Load Index This number shows how much weight one tyre can safely carry. You must match this to your vehicle's weight class. Speed Rating This tells you the maximum speed the tyre can handle safely. For example, H = 210 km/h, T = 190 km/h, etc. 2. Best Tyres for Personal Vehicles (By Model) a. Toyota Corolla / Honda Civic Recommended Tyre: Michelin Pr...

Engine Stalling

Engine stalling occurs when an engine unexpectedly stops running. It can happen under various conditions, such as when the vehicle is idling, accelerating, or decelerating. 

Stalling can be caused by a variety of issues related to the fuel system, air intake system, ignition system, electrical system, engine sensors, or even the engine control unit (ECU).


Common Causes of Engine Stalling.

1.Fuel System Issues,Low Fuel: Not enough fuel in the tank.Fuel Pump Failure: The pump may not be delivering fuel to the engine.

2.Clogged Fuel Filter: Restricts fuel flow.

3.Fuel Pressure Problems: Insufficient pressure in the fuel lines.

4.Air Intake System Problems:Dirty Air Filter: Restricts airflow to the engine.

5.Faulty Throttle Body: A dirty or malfunctioning throttle body can disrupt the air-fuel mixture.

6.Mass Air Flow (MAF) Sensor Issues: Incorrect readings can lead to improper air-fuel mixture.

7.Ignition System Malfunctions:Worn Spark Plugs: Poor spark can cause misfiring.Faulty Ignition Coils: Can lead to weak or intermittent spark.

8.Distributor Problems: In older vehicles, worn distributor cap or rotor.Electrical System Failures:Weak Battery: Can’t maintain power to the engine.

9.Alternator Issues: Fails to charge the battery adequately.Wiring Problems: Loose or corroded connections.

10.Engine Sensors Malfunctions:Crankshaft Position Sensor: A faulty sensor can cause the engine to stop.Camshaft Position Sensor: Similar to the crankshaft sensor, can cause stalling.Oxygen (O2) Sensors: Incorrect readings affect the air-fuel mixture.

11.Vacuum Leaks:Leaks in the vacuum system can disrupt the air-fuel ratio.Exhaust Gas Recirculation (EGR) Valve Issues:A stuck or malfunctioning EGR valve can cause rough idling and stalling.

12.Engine Control Unit (ECU) Problems:A malfunctioning ECU can send incorrect signals to the engine components, causing stalling.

Symptoms of Engine Stalling

  • The engine shuts off unexpectedly.
  • The vehicle may jerk or surge before stalling.
  • Difficulty restarting the engine after it stalls.
  • Warning lights on the dashboard, such as the check engine light.

Safety Concerns.

Stalling while driving can be dangerous, especially if it happens in traffic or at high speeds. It’s crucial to address the underlying issue promptly to ensure safe vehicle operation.Engine stalling requires timely diagnosis and repair to maintain vehicle reliability and safety.
