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

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.

Toyota victorious in Bahrain on Porsche’s LMP1 swansong

SAKHIR, Bahrain – Toyota denied Porsche a swansong victory in its final LMP1 appearance in the FIA World Endurance Championship by taking a commanding win in the 6 Hours of Bahrain on Saturday.

Porsche started from pole in the last competitive outing for the three-time Le Mans-winning 919 Hybrid car, only to lose out to Toyota’s Sebastien Buemi within the first half an hour of the race.

Porsche lost one of its cars from contention for victory after an errant bollard got stuck underneath Timo Bernhard’s No. 2 entry, leaving Nick Tandy to lead its charge in the No. 1 car.

Tandy moved into the lead just past half distance after a bold strategy call from Porsche to triple-stint the Briton after a fuel-only stop, vaulting him ahead of Anthony Davidson in the No. 8 Toyota.

Tandy’s win hopes were soon dashed when he tangled with a GTE-Am backmarker at Turn 1, sustaining damage that forced Porsche into an unplanned pit stop that put the car a lap down.

With the No. 7 Toyota losing two laps following a clash with a GTE-Pro car earlier on, Davidson, Buemi and Kazuki Nakajima went unchallenged en route to the car’s fifth victory of the season.

Porsche rounded out the podium with its cars, with the No. 2 leading home the No. 1, leaving Toyota’s No. 7 car to settle for P4 at the checkered flag.

Vaillante Rebellion clinched the title in LMP2 after a stunning fightback led by Bruno Senna, with the Brazilian securing his maiden motorsport championship win in the process.

GTE-Pro saw AF Corse complete a hat-trick of titles in 2017, with James Calado and Alessandro Pier Guidi wining the class’ first world championship recognized by the FIA, while Paul Dalla Lana, Pedro Lamy and Mathias Lauda sewed up the GTE-Am title.
