What causes tire scrubbing?
When your tires are not gripping at low speeds and sharp angles (such as backing out), the noises and vibrations that result are called “tire scrubbing,” and surprisingly, this is a completely normal reaction to specific external conditions.
Do skid marks go away?
This kind of mark on asphalt can last for months or even a year or two if they are particularly dark and the roadway is not well traveled. On other road surfaces, such as concrete, the marks result from the deposition of tire compounds onto the surface of the roadway.
Why does my suspension clunk when I hit a bump?
The rod’s bushings are a likely source of a clunking noise. Worn-out shocks or struts are also common culprits here. When the internal hydraulics wear out, the piston will move without the proper resistance and stop short when you hit a bump. With shocks, another thing to check for is loose or dried-out mounting bushings.
Why does my unibody have a rusted out suspension?
Unibody cars that get driven frequently on salted winter roads can also develop the rusted-out suspension pickup points. This is the worst-case scenario for these kinds of clunks where the only real fix involves a trip to the frame shop where new metal can be welded on.
What causes the tread to wear on a car tyre?
You will find this wear pattern on the driven wheels of high-power cars. High torque levels generated during strong acceleration, in stop-start urban traffic or when accelerating away from traffic lights can quickly increase wear of the tread in the centre of the tyre.
Why are there indentations in my car tyre?
Indentations in the tyre are best illustrated if you imagine tying a string around an inflated balloon and then gently pulling the string tighter. If the balloon is the tyre, the string is the embedded carcass cords, which are concealed by the rubber.
