2. Tire uniformity - Wikipedia

   en.wikipedia.org/wiki/Tire_uniformity

   Given a perfect tire, running on a perfectly smooth roadway, the force exerted between the car and the tire will be constant. However, a normally manufactured tire running on a perfectly smooth roadway will exert a varying force into the vehicle that will repeat every rotation of the tire. This variation is the source of various ride disturbances.

3. Bicycle tire - Wikipedia

   en.wikipedia.org/wiki/Bicycle_tire

   The net air pressure on the tire is the difference between the internal inflation pressure and the external atmospheric pressure, 1 bar (100 kPa; 15 psi), and most tire pressure gauges report this difference. If a tire is inflated to 4 bar (400 kPa; 58 psi) at sea level, the absolute internal pressure would be 5 bar (500 kPa; 73 psi) (+25% ...

4. Airless tire - Wikipedia

   en.wikipedia.org/wiki/Airless_tire

   Airless tires are attractive to cyclists, as bicycle tires are much more vulnerable to punctures than motor vehicle tires. The drawbacks to airless tires depend on the use. Heavy equipment operators who use machinery with solid tires may become fatigued. Any airless tire will be heavier than the rubber tire it is meant to replace.

5. Tire code - Wikipedia

   en.wikipedia.org/wiki/Tire_code

   Prior to 1964, tires were all made to a 90% aspect ratio. Tire size was specified as the tire width in inches and the diameter in inches – for example, 6.50-15. [29] From 1965 to the early 1970s, tires were made to an 80% aspect ratio. Tire size was again specified by width in inches and diameter in inches.

6. Tire - Wikipedia

   en.wikipedia.org/wiki/Tire

   The word tire is a short form of attire, from the idea that a wheel with a tire is a dressed wheel. [3] [4] Tyre is the oldest spelling, [5] and both tyre and tire were used during the 15th and 16th centuries. During the 17th and 18th centuries, tire became more common in print.

7. Low rolling resistance tire - Wikipedia

   en.wikipedia.org/wiki/Low_rolling_resistance_tire

   Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance.

8. Dunlop (brands) - Wikipedia

   en.wikipedia.org/wiki/Dunlop_(brands)

   Dunlop is a brand of tyre originally produced by the Dunlop Pneumatic Tyre Company from the end of the 19th century, taking its name from John Boyd Dunlop.The brand is used for many other products made from rubber or with rubber components and some with a looser connection to rubber.

9. Dynamic mechanical analysis - Wikipedia

   en.wikipedia.org/wiki/Dynamic_mechanical_analysis

   Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers . A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus .
