What Connects The Tire To The Car

what connects the tire to the car

Car tires might be simple parts of the car we do not take seriously. This starts from how we maintain them, clean them, and so much more. Other than the car tire, there are other parts important to keep the car moving. An example is what connects the tire to the car.

The hub is the part that connects the tire and the car. It is a hole-like part where the axle rests, and it is attached to the rotor. The hub is found at the center of the wheel and has five studs where the wheel is attached.

How to Grease and Clean a Car’s Hub

The car hub is a technical part of a car that requires maximum maintenance and care. It can be dangerous when you are running on a worn-out hub. Greasing and cleaning the hub is very important.

What you need

  • Hydraulic car jack
  • Paraffin or cleaning spirit
  • Wheel spanner
  • A small hammer
  • A piece of wood
  • High-quality grease

Step 1. Find an appropriate position to do this type of job. A flat surface is the best when you want to clean the hub.

Step 2. Choose the side of the car you want to start with and pump the hydraulic car jack to raise the wheel. Ensure you position well the car jack or else it can easily tip over.

Step 3. Use the wheel spanner to open the five nuts that attach the tire and rim to the drum. Make sure you use appropriate tools to remove the tire from the wheel.

Step 4. Disconnect the brake line from the wheel and ensure the brake fluid does not flow out. Use a plastic bag to hold the end of the brake line.

Step 5. Now use appropriate spanners and screwdrivers to remove the hub from the axle. The ball joint is what enters the hub’s socket.

Step 6. Place the whole wheel system down on the ground and study the hub system. A hub has bearings that help with the rotating of the wheel. Bearing are the basic parts that require lubrication.

Step 7. Put the wheel upside down on a piece of wood and use a small hammer to hit the bearing out of the hub. Ensure you are gentle to avoid destroying the hub.

Step 8. Once the bearing is out of the hub, look at its condition. Decide if the bearing requires maintenance or replacement.

Step 9. Use a piece of cloth to wipe off the old grease and also wipe the inside of the hub. Clean the inside of the hub until it is shiny. You can use the cleaning spirit or paraffin to remove the old grease from the bearing and inside of the hub.

Step 10. Then apply fresh grease on the outer sides of the bearings and also apply it to the hub. Be careful to use the recommended amount of grease because too much of it can lead to slippage. Also, avoid applying grease on the brake drums because it will reduce friction hence brake failure.

Step 11. Place the wheel system on the piece of wood and use a small hammer to hit the bearing back into the hub. Ensure the bearing is in position before you attach the wheel to the axle. Do not forget to reattach the brake tube and other small nuts. Finally, attach the tire and you are free to move to the next wheel.

Tire Maintenance Tips

Good tire maintenance tips should leave you with great tires that deliver a good performance. Here are some tips to consider.

  • Proper inflation of your tires is the first maintenance tip. Make sure you do not over-inflate your tires because they will wear out in the middle. Also, under-inflating your tire is also dangerous because it causes the sidewalls to touch more road surfaces.
  • Do a wheel alignment after a 25,000 km run. Wheel alignment helps the tires to have even tread wear and smooth drive on rough roads and potholes.
  • Ensure you do a frequent inspection of your tires. Inspect the pressure, wear and tear of the tire on a weekly basis. Sometimes take your car to a professional for proper inspection.
  • Grease and clean the hub of the wheel. This is the part that connects the car and the tire and it has a bearing that requires lubrication. Your tires will have a longer productive life when the bearing is lubricated and the hub is clean.
  • Go with the season while changing the tires. There are summer and winter tires. Both of these tires are designed to work well in different seasons. So go with the flow of the season and change your tires appropriately.
  • Replace all tires at once and avoid mixing up tires. Mixing new and old tires will lead to the dragging of the wheels and uneven wear and tear. Make sure you save enough money to buy all tires at once.
  • Ensure you repair punctures appropriately. It is advisable to take the tires to a professional for repairs. It is good to replace the tire when you see that the puncture is too big. Be careful and remove all foreign objects inside the tire.
  • Keep the spare tire in a cool and dark place to maintain the quality of the rubber. Excess heat will expand the pressure inside the tire, leading to unbalanced pressure. Also, avoid corrosive chemicals and gasoline on your tire because they can deteriorate the quality of your tire.
  • Avoid emergency braking when it is not required. Emergency braking can easily overheat the tire and cause wear and tear at one point of the tire. Moreover, always inspect your braking system to avoid sharp or loose brake pads.


What holds the wheels on a car?

All wheels depend on the ball and socket that is fixed on the hub. What we mean is that the hub is the basic part that controls the wheel. As long as the bearings are greased then you are ready to drive the car without worry.

Q2. What is the best braking system?

Hydraulic braking is the best but you must ensure there is no air bubble in the air fluid. The air bubbles will create a vacuum.

Q3. How much grease do you have to put in the hub?

The best amount of grease you can place in the hub is NLGI Nos. 1 or 2. Do not over-grease the hub or else it will slide.
