It’s a fact that the Chevy Camaro Z/28 has the widest front tires of any production car. At 305 mm wide, those tires produce tremendous grip–especially since they’re Pirelli P Zero Trofeo RS. In fact, they make so much grip, the Z/28 was spinning the tire around the wheel under braking–the Z/28 was, in effect, outrunning its tires, or at least their ability to grip the wheels. It’s an unusual problem for a production car, but it’s a good one to have–too much grip is just enough.
Camaro Z/28 engineers had to come up with a creative solution to prevent tires from slipping on the rim during hard braking and acceleration on the track. Part of the cause also comes down to the Brembo carbon ceramic brakes, which provide tremendous stopping power for the large but track-worthy Z/28. But regardless of the cause, Chevy had to find a fix for the tire-on-wheel slippage issue. If Chevy hadn’t found a solution to the problem, it could have resulted in the wheel/tire package going out of balance–like the wheels they’re mounted on, tires aren’t perfectly uniform around their circumference. That’s why the wheel/tire package is balanced as a unit. Typically, Chevy says the tire-wheel slippage issue is solved through the use of an abrasive paint along the bead of the wheel, where the tire seats. The Z/28 team tried this, and found it wasn’t enough to prevent the problem. Want to know what finally worked? Check out the video above and the rest of the story at MotorAuthority.com
TPMS, or Tire Pressure Monitoring Systems, alert you if you have unsafe air pressure in any of your tires. These monitors are installed in your wheels, and alert you through a symbol on the dashboard that looks a little like a flat tire. In 2007, the Federal TREAD act (or Transportation Recall Enhancement, Accountability and Documentation) began requiring all new cars and light trucks come equipped with TPMS. This legislation, like that requiring air bags, helps to keep you safe on the road.
With the price of gas continuing to increase, many people are looking for ways of increasing their car’s fuel efficiency. The more miles per gallon you can get, the less you have to fill up and the more money you can save. While some would say the answer is to buy a hybrid vehicle, these cars are still fairly expensive, plus it makes no sense to buy a new car if the one you’re currently driving isn’t that old and is in good running condition.
