RAIN TIRES ARE ON THE WAY FOR NASCAR IN 2018

CONCORD, North Carolina — The rain that was a bane of NASCAR fans Saturday at Charlotte Motor Speedway will be anticipated next year.

While rain delayed Saturday’s Xfinity race and the threat of it moved the start of Sunday’s Cup race up an hour, rain next year won’t be as much of a problem.

With NASCAR racing on the track’s roval, rain tires will be available for both series a year from now. It’s a decision NASCAR made a couple of weeks ago, Stu Grant, general manager of worldwide racing for Goodyear, told NBC Sports.

“There was some debate about whether or not we should run rain tires on the roval because of how much you run on the bankings and the speed you may or may not have,’’ Grant said. “There was some due diligence on whether or not rain tires should be run. A lot of modeling, a lot of simulation and it looks like the speeds are going to be comparable to Watkins Glen and NASCAR has made the call, yeah, Goodyear go ahead and have rain tires available for this race a year from now.’’

The rain tires will be the same tires available at other road courses that NASCAR races.

Goodyear also will have rain tires at an Oct. 17-18 test on Charlotte’s roval with Chip Ganassi Racing, Richard Childress Racing, Stewart-Haas Racing and Furniture Row Racing.

Grant said the test procedure will be the same as other tires tests but admits this will be different since this is a new track for teams.

“The banking that you run here adds a whole different element from a car setup standpoint,’’ Grant said. “It’s different than trying to set up the car for a road course at Sonoma for example. We’re going to learn a lot about the tires and the compound necessary to come here with a good race tire, but the teams are going to learn a lot about how to set the car up properly.’’

The base tire for that test will be the tire combination that is run at Watkins Glen.

“The issue for us is to figure out what is the right compound to marry that road course construction with the asphalt on the road course and the oval pieces,’’ Grant said. “We have purpose-built a number of test tires to make sure we have the right combination.’’

One change that helped Goodyear was the addition of the chicane on the backstretch of the oval to slow cars before entering Turns 3 and 4. Cars will exit the road course portion in Turn 1 and run on the oval through Turn 2 and the backstretch before reaching the chicane.

“If you look back, the original layout, it did not have the chicane on the back,’’ Grant said. “Think about it, you come out of (Turns) 1 and 2 and all the way down the backstretch and through 3 and you can generate some pretty high speeds. It’s difficult to be able to get any kind of a comprise on the car or the tire that allows you to get through the super slow part in the road course and have the durability and the suspension settings on the car to be able to get through Turn 3 at high speeds.

“The chicane was added on the backstretch to slow the entry into 3 and allow you to run a proper road course setup on your car, a good road course tire and run rain tires.’’
