Estimation of vehicle sideslip, tire force and wheel cornering stiffness. The second year, Jeep lowered the suspension, which hurt ground clearance but made on-road cornering better and improved the ride and entry height; for serious off-roaders, the later Renegade model had higher ground clearance and other concessions to rocks, mud, streams, and dirt. A more detailed look at the Magic Formula appears in the next section. And suddenly — you hit something in the road. When cornering, several forces you learned in physics class act on the vehicle as it turns and changes direction, which in turn, puts the tires under excessive stress and force. You’re driving along, minding your business. D Heritage Classic. 275/65-R18 tires are 1. We feel that lateral stiffness is the most important factor to how a wheel feels on the trail; wheels with high lateral stiffness don't have that "floppy" feel in slow rocky turns and they give the bike that "on-rails" feeling around a banked corner. Three common parameters that have been widely used by numerous tire-manufacturing companies for indoor tests are cornering stiffness, lateral stiffness, and distortion stiffness. Flat Tire Service If your vehicle's spare tire is inflated and serviceable, it will be installed to replace a flat tire, when possible.
