Goodyear has to change Bristol tyres

NASCAR officials have announced that the specification of right-side tyres will be changed for Sunday's NASCAR Sprint Cup Series race at Bristol Motor Speedway, following excessive wear during the opening practice session on Friday. Robin Pemberton, NASCAR's vice president for competition, announced following practice for the Nationwide and Sprint Cup series that a different specification of right-side tyres will be used in Saturday practice and Sunday's race, after cords became visible - especially on right rears - after only 30 laps in some cases, when they should last a full fuel run which amounts to nearly four times that distance. The issue has affected both Nationwide and Cup teams and it will be handled differently for each series.
