General Motors Tire-Wheel Systems Lab abuses tires for 2011 Buick Enclave
At the General Motors Tire-Wheel Systems Lab on GM’s Milford Proving Ground, staff from a range of major tire manufacturers joined in the tire abuse, giving new meaning to the old adage, "where the rubber meets the road."
According the latest GM news release, each tire vying to be chosen for the Enclave went through 25 different lab tests to gauge how well they hold up against simulated real-world abuse.
Some tests mimicked hitting a curb at low speed or smashing into a pothole. Lab dynamometers with specially grained sandpaper were used to replicate tens of thousands of miles of road wear.
“Tires are the only contact point you have with the road,” said Tire Engineering Group Manager Dave Cowger. “Your tires influence everything from fuel economy to steering and handling, road noise, and braking. So we beat the heck out of these tires in the lab to make sure they have the right traction, fuel economy, durability and other characteristics.”
