Sidewall Stiffness

…An "aggressive" tread design that could better resist hydroplaning or provide enhanced snow traction would also generate more noise. And a "stiff" sidewall that could provide responsive handling and high-speed stability would also reduce ride comfort. These opposing goals require blending and…

…performance designed to match the needs of their vehicles. Tire deflection (the tread and sidewall flexing where the tread comes into contact with the road) will remain as originally designed and excessive sidewall flexing and tread squirm will be avoided. Heat buildup will be managed and rolling…

…impressive characteristics of the BFGoodrich g-Force Rival were: * Precise turn-in - Thanks to very stiff sidewalls, initial turn-in and transitional response were direct and immediate. Stiff sidewalls are something that I especially like in a performance tire, so this was a big plus to me *…

…between H and W depending on size, the Turanza Serenity Plus also offers good handling characteristics without abusing the driver with an overly stiff sidewall. The tire's movements feel composed, direct and stable at highway speeds. Serenity Plus tires feature a 75,000-mile warranty making it…

…Large, solid outboard tread blocks and BFGoodrich’s Extreme Tread Edge (ETE) shoulder design wrap the tread compound farther down the sidewalls for predictable feedback and maximum cornering grip from start to finish. Also, the g-Force Rival has just been approved for SCCA use! Direzza…

…making turns with the vehicle, even at moderate speeds. Why does this occur? Most run-flats have stiffer sidewall construction to maintain stability during an air pressure loss. Stiff sidewall designs are what primarily give run-flat tires their quick steering response and firmer ride. Installing…

…V105 has not yet made a big splash in the marketplace, but it has exceptional grip. I'm also a fan of the responsive handling that its stiff sidewalls provide. To see how the tire performed during our in-house test, read "New Yokohama ADVAN Sport V105 Tested." View all Max Performance…

…or cooling fins on the sidewall. Bridgestone also molded a NanoPro-Tech Sidewall reinforced rubber compound into the tire's sidewall. These two features reduce heat generated and aid in moving the heat away from the sidewall. This allows a reduction in sidewall stiffness, which results in a more…

…(which does periodically wear out and requires replacement). Additionally, auxiliary support systems promise better ride quality because their sidewall's stiffness can be equivalent to today's standard tires. The disadvantage to auxiliary supported systems is that their unique wheels will not accept…

…balancing. This advanced balancing spins the tire against a roller to account for any variation in stiffness of the tire's sidewall. It's common for there to be a stiff spot in the sidewall, which can cause a ride disturbance even if a wheel and tire are perfectly balanced for weight. How do…
