Notes: Teams in both the NASCAR Sprint Cup and Xfinity Series will run  the same tire set-up at Las Vegas this weekend . . . this is the first  time these teams will run this combination of left- and right-side  tires at Las Vegas, though Sprint Cup teams did run this right-side  tire code (D-4630) at Talladega last October . . . compared to what was  run at Las Vegas last year, this right-side features a compound change  for better wear . . . this weekend's left-side tire code (D-4652)  features both construction and compound changes vs. the 2014 Las Vegas  left-side . . . the construction change is to align this track with  other, similar tracks; while the compound change will enhance grip . .  . as on all NASCAR ovals greater than one mile in length, teams are  required to run inner liners in all four tire positions at Las Vegas .  . . air pressure in those inner liners should be 12-25 psi greater than  that of the outer tire.
