Brooklyn, MI (Sports Network) - Officials from NASCAR and Goodyear seemed
pleased with their decision to change the left-side tires on the cars for
Sunday's 400-mile Sprint Cup Series race at the newly repaved Michigan
An additional Sprint Cup practice session was held on Saturday at Michigan.
The 75-minute session was held immediately following the Nationwide Series
race here, which was won by Joey Logano.
After several teams experienced tire blistering during Thursday and Friday's
practice sessions at Michigan, NASCAR and Goodyear made the decision to use a
tougher left-side tire for this race.
During Friday's second practice, Greg Biffle posted the fastest lap at 204.708
mph. The higher than expected speeds at Michigan caused significantly higher
left-side tire temperatures and therefore blistering.
Goodyear shipped in enough tires for teams to have 10 sets of them for the
race, which is the original NASCAR set limit for this event. Teams will run
their original allotment of right-side tires.
Speeds were considerably less during Saturday's practice compared to the past
two days. Tire temperatures were lower as well, and there were no reports of
Biffle topped the speed charts in this session with a lap at 195.647 mph.
"From what we saw in this final practice this evening, we're very comfortable
with (the tires)," said Greg Stucker, who is Goodyear's Director of Race
Tires. "I think all of our observations are reinforcement that, from a tire
perspective, it was the right call."
Stucker also noted that Mark Martin, who had a number of issues with his tires
during Friday's practice sessions, made a 21-lap run in the final session and
said the tires "looked beautiful."
NASCAR gave teams the extra practice time to get familiar with the new tire as
well as make further adjustments to their race setups.
"We have to treat this like we haven't been here," NASCAR Vice President of
Competition Robin Pemberton said prior to the start of practice. "It's a new
tire for this track surface, and we need to give the teams enough time to
practice on it."
The additional session had mixed reviews from drivers. Some were limited on
their practice time due to engine concerns.
"Our engine guys don't like us to run over a certain amount of laps, so I'm at
my limit and can't practice anymore," Earnhardt Jr. said after completing 26
laps. "I would like to practice more, but I can't. My car isn't as good as I
want it to be, but I can't practice anymore. This ain't cool."
Earnhardt Jr.'s last Sprint Cup win came four years ago at Michigan (143 races
Earlier in the day, Marcos Ambrose won the pole for this race after he easily
shattered the track qualifying record here with a lap at 203.241 mph. Forty
drivers in the qualifying session recorded a faster speed than the previous
track record of 194.232 mph, set by Ryan Newman in 2005. Nineteen of them
topped 200 mph.
"We were out there trying to save miles on the engine, so we never really
busted off a good run," said Ambrose, who was 11th quickest in practice. "The
tire is very different. It hasn't got much grip. You are loose in, shake in
the middle and then on the gas spin yourself out.
"It feels unbalanced and a little bit wobbly, and you don't want to be wobbly
at 200 mph. You want to feel like the car is underneath you. I think we did
enough stuff during practice to get a feel for what we need. We will make some
adjustments tonight and get ready for tomorrow."
Newman applauded NASCAR and Goodyear for the tire change.
"I think it was absolutely the right call," he said. "The tire temperatures
are way down. It was a good call by Goodyear and NASCAR."
