NASCAR: Goodyear says higher speeds contributed to Tony Stewart’s test crash at Indy

3 Comments

Goodyear said that “increased, sustained speed” over a 20-lap run led to his crash during this week’s tire test at the Indianapolis Motor Speedway.

“Tony was approaching the end of a very strong 20-lap run, with his lap times as much as a second faster than what has become the norm at Indianapolis at that point of a run,” said Goodyear racing director Greg Stucker in a statement.

“It appears that increased, sustained speed over that run generated a significant amount of heat, which eventually caused the right-front to go down.  Those are the conditions we have to consider in making the right decisions for the race.”

Stewart did talk with NASCAR medical personnel after the crash, which took place during a part of the test that was closed to the media. However, he was OK afterwards.

The statement says that Goodyear will continue to talk to teams before coming up with a final recommendation on tires for the Brickyard 400 at Indy next month.

However, Goodyear general manager of worldwide racing Stu Grant has told Motor Racing Network that a different, harder left-side tire will be used for the Brickyard to address what happened with Stewart – who was running the 2013 tire combination on both the left and right sides at the time of his crash.

Grant told MRN’s Dustin Long that by running a harder tire on the left side, the car will slow down and help save the right-side tires.

“We’re going to stay with the 2013 right-side tire for this year because we know that that compound rubbers in the race track,’’ he added.

“Wear and rubbering in that race track is a big deal as you know from 2008. We were able to run a gas (run) on the right side tires. We’re confident that our wear is going to be OK.’’

In addition to releasing their findings on the Stewart test crash, Goodyear announced that it would run the same left-side tire from 2013 at Chicagoland as well as the right-side “multi-zone” tire that was ran earlier this year at Texas.

Also, Kentucky is likely to feature the same left/right tire combination as last year following a confirmation test. More tire tests are slated for Richmond in early July and Homestead-Miami in late August.

While the FIA Formula 1 World Championship is still two months away from beginning its 2018 season, this past week did bring about news items that filled out the 2018 grid and shed some light on individual team and car launches as the season-opening Australian Grand Prix draws closer.

Below is a recap of F1 news from this past week:

Williams Signs Sirotkin for 2018 Drive, Names Kubica as Reserve Driver

The saga of the second seat at Williams Martini Racing was finally resolved early on in the week, with former Renault Sport F1 Team test driver Sergey Sirotkin officially confirmed as a teammate to the incumbent Lance Stroll in 2018.

The announcement concluded months of speculation that saw multiple drivers test for the team in an auditioning capacity. Most notably, Robert Kubica looked to be a main contender for the seat before Sirotkin emerged as the favorite.

However, Kubica, who has not raced in Formula 1 since a devastating rally accident in 2011 left him with brutal injuries to his right arm, was named as a reserve and development driver for the team.

This announcement also completes the 2018 Formula 1 driver lineup, with all 11 teams having their seats now filled. Among those who were left without F1 drives are Paul Di Resta, who drove for Williams at the Hungarian Grand Prix in relief of Felipe Massa and even tested with them during the Winter months, and Antonio Giovinazzi, who filled in for Pascal Wehrlein at the Australian and Chinese Grands Prix.

Former Red Bull Racing and Scuderia Toro Rosso driver Daniil Kvyat is also without a race seat for 2018, but did sign on with Scuderia Ferrari as a development driver.
