Tire drivability discusses the feedback a tire gives the driver and introduces the physics of tire slip angle. Generally softer tires will provide a higher peak level of grip at a lower temperature and have a narrower temperature window then harder tires. Tire slip angle is non-linear; it takes some slip for the tire to begin to grip. As the tire reaches a sweet spot usually about 1° the grip begins to fall away with increased slip angle. Slip angle factors will differ for acceleration, braking and turning.
