Goodyear Tire officials said Sunday part of the first day of their two-day tire test next week at Charlotte Motor Speedway's infield road course will be spent determining the final location of the backstretch chicane.
When the final design of the 2.4-mile course was unveiled last week, it included a permanently-designed chicane off Turn 4 and a temporary chicane entering Turn 3 on the backstretch.
The participating teams, track and Goodyear officials will test several different options for the backstretch chicane on Tuesday, the first day of the test.
"NASCAR and the race track haven't nailed down what exactly the backstretch chicane is going to look like. We have three different options that we'll evaluate," Greg Stucker, Goodyear's director of racing told Motorsport.com on Sunday.
"That's most of (Tuesday) morning, finding out which chicane works the best operationally for the race track and to try to hit the target speeds that we're looking for."
Four drivers are participating in the two-day test: Kurt Busch, Paul Menard, Martin Truex Jr. and Jamie McMurray.
