The coils seen over (behind) the tires of a car are the springs that provide flexible movement of the axles/and wheels to smooth out the bumps when driving. Shock absorbers damp the motion so the car doesn't bounce like a pogo stick. Usually the shock absorber is built into the coil assembly to form what is called a "strut".
On a bicycle, the coils do the same job, and usually have a shock absorber inside the coils.
The coils on a ford escape are over the sparkplug type.
With those rubber bands for tires I woulnd suggest you over inflate. Tires need alittle expansion for bumps and potholes on the road. Car 28-32lbs. Truck/SUV 35-40lbs.
They can be dirty or the system can be low on freon.
No. You can smooth the clay over with a rib to make the coils smooth, both on the inside and outside of the pot.
You mean bridges? Those would be called puentes.
Yes, I have owned a set of 4 for over 4 years and I just had the tires checked, still has 90% tire tread after 30K miles! Don't listen to those that say if it's not name brand it's all junk, sometimes yes, but sometimes no and these are great tires.
Cardigans!!
Pneumatic will ride smoother, but you have to worry about a puncture and check the air pressure regularly. Run flat are expensive and do not last as long. I would recommend foam filled tires over either of those options. They will not ride as good but they are worry free albeit a little expensive.
Coils are over spark plugs.
Rubber tires are preferred to steel tires because if we had steel tires driving over the smallest pebble would be a very bumpy ride. Rubber tires are flexible and will be smooth when going over rocks. Not to mention, if we had steel tires the government would have to replace the roads everyday with the amount of people tearing them up with steel tires. Also, rubber tires wear out and that means you will have to buy new ones again..
Coiling is among the most ancient forms of pottery making. The potter forms coils by rolling clay and then builds up forms by stacking the coils on top of each other and attaching them with liquid clay or slip. The coils are then usually smoothed over, making a smooth surface. Native American pottery is usually made this way and then the pots are covered with colored slip and decorated.
Yes, over-inflation can cause vibration. It will also cause harsh ride, tires will wear in the center of the tire, and handling and stopping will be adversely effected. Never over-inflate your tires. Follow the vehicle manufacture's recommendations.
