2. Uniform Tire Quality Grading - Wikipedia

   en.wikipedia.org/wiki/Uniform_Tire_Quality_Grading

   The coefficient of friction rapidly reaches a maximum value at about 10-20 percent slip, and then declines as the longitudinal slip values increase to 100 percent, which represents a fully locked tire. The maximum coefficient of friction in the 0-100 percent slip range is termed "peak" coefficient of friction, and the lower coefficient value ...

3. Tire load sensitivity - Wikipedia

   en.wikipedia.org/wiki/Tire_load_sensitivity

   Coulomb friction theory says that the maximum horizontal force developed should be proportional to the vertical load on the tire. In practice, the maximum horizontal force Fy that can be generated is proportional, roughly, to the vertical load Fz raised to the power of somewhere between 0.7 and 0.9, typically.

4. Scrub radius - Wikipedia

   en.wikipedia.org/wiki/Scrub_radius

   The term scrub radius derives from the fact that either in the positive or negative mode, the tire does not turn on its centerline (it scrubs the road in a turn) and due to the increased friction, more effort is needed to turn the wheel. Large positive values of scrub radius, 4 inches/100 mm or so, were used in cars for many years.

5. Rolling resistance - Wikipedia

   en.wikipedia.org/wiki/Rolling_resistance

   Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed.

6. Low rolling resistance tire - Wikipedia

   en.wikipedia.org/wiki/Low_rolling_resistance_tire

   In the early 2010s in Canada, Transport Canada tests were planned on a number of different tires mounted on 15 and 16-inch rims – the most common tire sizes in Canada at that time – to determine how rolling resistance is influenced by vehicle size, tire width and profile.

   For example, if you’ve already set aside $25,000 in a savings account, you could open a six-month CD with an annual percentage yield (APY) of 4.50 percent and withdraw $556.31 in interest ...
