Different tire compound being tested at Kentucky

Goodyear officials will look to do more than verify the tire package for this year's Monster Energy NASCAR Cup Series race at Kentucky Speedway when they hold a two-day test Tuesday and Wednesday at the 1.5-mile track.

"We've also got some things to try to actually promote a little more wear on a repaved surface, which is something we haven't been able to do," Greg Stucker, director of race tire sales for Goodyear, told NASCAR.com on Sunday. "The guys have kind of taken a different approach on compound formulation to see if we can't actually generate some wear on what we project to be a fairly smooth surface."

The 1.5-mile track was repaved before last year's tripleheader; a portion of the asphalt has since been replaced.

Testing at Kentucky are #1-Jamie McMurray (CGR), #3-Austin Dillon (RCR), #41-Kurt Busch (SHR) and #77-Erik Jones (FRR).

Two tire tests have been held this season, at Las Vegas Motor Speedway and Indianapolis Motor Speedway. A test at Michigan was postponed due to weather and has been rescheduled for July 10-11. Because of the date change, the MIS test will now be dealing with potential 2018 changes rather than focused on this year's races at the 2-mile track.
