INDYCAR, Firestone prepared if tires ‘blister’ at Texas

Leave a comment

FORT WORTH, Texas – In an attempt to avoid a situation experienced last year when the Firestone Firehawk tires “blistered” at Texas Motor Speedway, INDYCAR and the tire manufacturer came prepared for Thursday night’s practice.

Two different tire compounds are in the garage area as NTT IndyCar Series teams prepared for a two-hour practice session scheduled to get underway at 8 p.m. Eastern Time Thursday. Each team has 14 sets of the “primary” tire compounds, but if any teams experience blistering issues in the two-hour practice, there are 11 sets of an “alternate” tire compound available per team.

INDYCAR will also extend the practice session if teams have to use the “alternate” tires.

If there are no issues with the primary tire compound, the alternate tires will not be brought out and the teams will prepare for this weekend’s DXC Technology 600 as usual with one tire compound used for practice, qualifications and Saturday’s race.

The tires would be used on the right-side of the car.

“We tested in October and Texas is a pretty severe track with pretty severe temperatures, we tested several compounds and we had a lot of blistering in that test,” Cara Adams, Chief Engineer, Bridgestone Americas, told NBCSports.com. “We had one compound that didn’t blister, but the teams didn’t like it that much. We went back for a second test in March. It was a little cooler, but we developed several compounds that didn’t blister at all.

“Our race tire here is a much cooler running and faster wearing tire. We don’t expect to see blistering on that primary tire. Doing our due diligence and being very prepared we came up with a backup tire.”

Firestone notified the teams last week at Detroit that an additional tire would be made available if there are issues with the primary tire across the field.

“If there are no issues, there are no reason we will run the alternate tires,” Adams said. “Teams have 14 sets for the race weekend. If they switch to the backup tire, they will use two sets tonight and have nine sets of tires for the race itself.”

This is also the first time in at least 15 years that a Thursday night test has been added to the IndyCar schedule at the 1.5-mile, high-banked Texas Motor Speedway. Saturday’s race will be contested at relatively the same time period as Thursday night’s test – 7 to 9 p.m. Central Time.

Since then, practice and qualifications would be held on Friday during the daytime and the race would be held Saturday night.

“We work really closely with IndyCar and decided to have this practice to make sure we were prepared,” Adams said. “The challenge for Texas is to come up with a tire that wears sufficiently but does not blister. It’s something our compounders have worked together with compounders across the Bridgestone organization to come up with a tire that wears more quickly.

“The aero specifications have changed a little bit and the track has lost grip from last year, so it will be interesting to see what the conditions are tonight. We made sure we met with the chief engineer and team manager from each team to make sure they had no concerns and were grateful we had a plan for a backup tire.”

Rob Edwards, Chief Operating Officer at Andretti Autosport and race strategist for Alexander Rossi, was blunt with his thoughts on the tire situation.

“I prefer we have one tire (compound) and just get on with it,” Edwards told NBCSports.com.

Keating stripped of Le Mans GTE-Am win; No. 68 Ganassi entry also disqualified

FIA stewards announced Monday that two Ford GT entries have been disqualified from this year’s 24 Hours of Le Mans, including the GTE-Am class-winning No. 85 entry from privateer Keating Motorsports.

Also DQ’d was the factory No. 68 Chip Ganassi Racing entry of Joey Hand, Dirk Mueller and Sebastien Bourdais, which initially finished fourth in the GTE-Pro class.

Both entries were found in violation of fuel capacity regulations, with the No. 85 entry also failing to meet the minimum refueling time during pit stops.

The refueling system on the No. 85 entry, driven by Ben Keating, Jeroen Bleekemolen and Felipe Fraga, measured a time of 44.4 seconds during a stop, just shy of the minimum required time of 45 seconds.

As a result, the team was initially issued a 55.2-second post-race penalty by officials, which elevated the No. 56 Team Project 1 Porsche 911 RSR of Joerg Bergmeister, Patrick Lindsey, and Egidio Perfetti to the class win.

The time penalty was calculated by the difference in the refueling time (0.6 seconds) multiplied by the amount of pit stops made by the team (23), then multiplied by four.

The No. 85 entry was set to finish second in class, but then received an outright DQ after its fuel capacity was also revealed to be 0.1 liters above the maximum permitted capacity of 96 liters.

As for Ganassi’s No. 68 entry, it was found to have a fuel capacity of 97.83 liters, which is above the maximum allowed capacity of 97 liters for the GTE-Pro Fords.

The No. 67 Ford of Andy Priaulx, Harry Tincknell, and Jonathan Bomarito subsequently moves up to fourth, and the No. 69 Ford of Scott Dixon, Ryan Briscoe and Richard Westbrook moves up to fifth.
