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...

Removal of Ball bearing from four wheel drive Vehicle.

Removing a ball bearing from a wheel in a four-wheel-drive vehicle requires proper tools, patience, and caution. Follow this step-by-step guide to ensure a safe and successful process.

Tools You’ll Need:

1. Socket set

2. Jack and jack stands

3. Lug wrench

4. Pry bar

5. Screwdrivers

6. Hammer and punch

7. Bearing puller or slide hammer

8. Torque wrench

9. Grease and rags

10. Safety gloves and goggles


Steps to Remove the Ball Bearing:

1. Prepare the Vehicle: Park on a flat surface and engage the parking brake. Loosen the wheel lug nuts slightly with a lug wrench.

2. Lift the Vehicle: Use a jack to lift the wheel off the ground. Secure the vehicle on jack stands for safety.

3. Remove the Wheel: Fully loosen and remove the lug nuts. Take off the wheel to expose the hub assembly.

4. Remove the Brake Assembly: Detach the brake caliper using the socket set. Remove the brake rotor (this might require a hammer tap if it’s stuck).

5. Access the Hub Assembly: Remove the dust cap from the hub if applicable. Unbolt the axle nut using a socket set. Push the axle inward slightly to free it from the hub spline.

6. Detach the Hub: Unbolt the hub assembly. Use a bearing puller or slide hammer to remove the hub from the knuckle.

7. Remove the Bearing: Use a hammer and punch to remove the circlip or retaining ring. Use a bearing puller or hydraulic press to press out the bearing.

8. Inspect and Clean: Inspect the hub and knuckle for damage or wear. Clean the area thoroughly before installing a new bearing.

Important notes.

1. Always replace ball bearings with new ones.

2. Follow the manufacturer’s torque specifications during reassembly.

3. Ensure alignment is checked after reinstalling the bearing to prevent uneven tire wear.
