Goodyear brings a little bit of Kentucky to Texas: The big story of the week is the repave and reconfiguration of this week’s stop on the NASCAR circuit – Texas Motor Speedway. 
The asphalt mix the track used is said to be the same as the one on Kentucky Speedway’s repave last year.  Along with the new surface, Texas reduced the banking in turns one and two. 
With the timing of the Texas project being so tight and work being completed in early-March, there was not sufficient time for Goodyear to conduct a tire test at the facility and then build the quantities needed for the race weekend in early-April. Given the commonality of the asphalt mix, along with the results of the Kentucky race last July, the decision was made to bring a tire set-up with the same tread compounds as raced at Kentucky.
Notes: Teams in both the Monster Energy NASCAR Cup and Xfinity Series will run the same tire set-up at Texas this weekend. This is the same left-side tire code (D-4688) teams in all three national NASCAR series ran at Kentucky in 2016. There is a brand new right-side tire code (D-4718), which features the same tread compound as the right-side Cup teams ran at Kentucky last July, with a minor construction change.
