2. Tire uniformity - Wikipedia

   en.wikipedia.org/wiki/Tire_uniformity

   Tire uniformity. Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation, lateral force variation, conicity, ply steer, radial run-out, lateral ...

3. Uniform Tire Quality Grading - Wikipedia

   en.wikipedia.org/wiki/Uniform_Tire_Quality_Grading

   UTQG ratings (top) and tire code (bottom) on sidewall of Continental ContiProContact tire. Uniform Tire Quality Grading, commonly abbreviated as UTQG, is a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction. The UTQG was created by the National Highway Traffic Safety Administration in ...

4. Tire code - Wikipedia

   en.wikipedia.org/wiki/Tire_code

   The load index on a passenger-car tire is a numerical code stipulating the maximum load (mass, or weight) each tire can carry. For load range "B" tires, ETRTO (ISO-Metric) standards specify the load index rating at an inflation pressure of 36 psi (250 kPa) (table below), while P-Metric standards measure the load capacity at an inflation ...

5. Radial tire - Wikipedia

   en.wikipedia.org/wiki/Radial_tire

   A radial tire (more properly, a radial-ply tire) is a particular design of vehicular tire. In this design, the cord plies are arranged at 90 degrees to the direction of travel, or radially (from the center of the tire). Radial tire construction climbed to 100% market share in North America following Consumer Reports finding the superiority of ...

6. Formula E car - Wikipedia

   The Spark Renault Spark-Renault SRT 01E (Spark Gen1) which was used from season 1 through 4 (2015–16 to 2017–18). Even though the FIA originally planned for the category to be open to various chassis manufacturers, [2] the only licensed Formula E model for the inaugural season (2014–2015) was the Spark-Renault SRT 01E.

7. Low rolling resistance tire - Wikipedia

   en.wikipedia.org/wiki/Low_rolling_resistance_tire

   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.
