The Eagle F1 Supercar EMT is Goodyear's self-supporting, run-flat Max Performance Summer radial developed as Original Equipment for sports cars, (C-6 Corvette equipped with Chevrolet's Z51 Performance Package and C-6 Corvette Z06), and performance sedans (Cadillac CTS-V). Eagle F1 Supercar EMT tires emphasize dry road traction and handling, and feature Goodyear's self-supporting Extended Mobility Technology (EMT) to provide temporary mobility even after a complete loss of air pressure while eliminating the traditional spare tire and wheel to allow more storage and luggage space. Like all summer tires, they are not intended to be driven in snow.
Goodyear's warranty states: "Ultra high-performance summer tires are not recommended for winter use, and tread or shoulder cracking on those tires resulting from winter use will not be covered under our warranty."
Eagle F1 Supercar EMT tires feature a high-grip Goodyear AAtrax tread compound (the AAtrax name emphasizing that the Eagle F1 Supercar EMT earns the highest "AA" Uniform Tire Quality Grade wet traction rating) molded into a slightly reduced tread depth (9/32" instead of traditional 10/32") asymmetric tread design that combines large outer shoulder and intermediate tread blocks to increase initial steering response and cornering stability with a solid center rib to maintain constant road contact and enhance straight-line tracking. Wide circumferential grooves and smaller interior tread and shoulder blocks help water escape from between the tire and the road to maintain wet traction and hydroplaning resistance. The tire's structure includes twin, high-tensile steel belts reinforced with spirally wound Aramid to distribute the vehicle's load across the tire's footprint providing high-speed durability and uniform ride qualities. Rayon body plies enhance high temperature and high-speed durability while exterior sidewall rim flange protectors help guard wheels against curb damage.

Goodyear’s original Eagle F1 Supercar EMT Max Performance Summer Run-Flat tire has been Original Equipment on
Corvettes with the performance handling or Z06 packages since the C6 chassis debuted in 2005. For the 2011
Corvette Z06, Chevrolet has chosen Goodyear’s new 2nd generation Eagle F1 Supercar G: 2 RunOnFlat tires as
Original Equipment.
The Eagle F1 Supercar G: 2 RunOnFlat combines a race-inspired tread compound molded into a unique asymmetric pattern designed to deliver significant dry grip with wet road capability. Since Corvette tire sizes won’t work on Tire Rack’s standard test cars, a formal test at our facility isn’t possible.
However several members of the Tire Rack team did have the chance to experience the new Eagle F1 Supercar G: 2 RunOnFlat during a visit to the Bob Bondurant School of High Performance Driving in Phoenix, AZ. The Bondurant crew outfitted two of their Corvette Z06s with scuffed-in, full tread depth tires to compare back-by-back. The first car wore original Eagle F1 Supercar EMT tires and would serve as our baseline reference, while the second car was fitted with the new Eagle F1 Supercar G: 2 RunOnFlat tires.
After some familiarization laps in a standard C6 Corvette with the Z51 performance package on Eagle F1 Supercar EMT tires, we were ready to compare tires on a pair of the school’s bright red 2008 C6 Corvette Z06s. The Z06 brings big brakes, tuned suspension and just over 500 horsepower to the equation - enough to challenge any tire holding it to the ground.
Going out first for a few laps in the car equipped with the original Eagle F1 Supercar EMT confirmed our initial impressions. It’s apparent Chevrolet and Goodyear fine-tuned this combination for the C6 Corvette, as car and tire seem to be in sync with each other. Steering response was smooth and linear, turning down to the apex with precision. Overall vehicle balance was good, too, with both the front and rear tires reaching their grip limit at the same time. The Z06’s traction control engaged occasionally and predictably, mostly when we were simply too aggressive with the throttle on corner exit.
Then we were back into the pits to switch to the car with the new generation Eagle F1 Supercar G: 2 RunOnFlat. It only took driving into the first turn to realize the new generation tire was working on a whole new level of performance. The most obvious change came in steering response - this car/tire combination feels directly connected to the driver, responding almost instantly to steering inputs. Several drivers commented on how the Eagle F1 Supercar G: 2 RunOnFlat felt more like a dedicated track tire than a street tire. Cornering power at the apex was impressive and perceptibly better than with the original Eagle F1 Supercar EMT. We did not experience as much intervention from the Corvette’s traction control system during hard acceleration away from the corners, and braking traction felt sure-footed, too. As a package, the car fitted with the Eagle F1 Supercar G: 2 RunOnFlat felt more connected to the track, resulting in higher driver confidence and quicker overall track speed.
To find out just how fast around the road course the Eagle F1 Supercar G: 2 RunOnFlat was, we put Bondurant’s chief instructor Mike McGovern behind the wheel. Mike knows the track, cars and original Eagle F1 Supercar EMT tire like the back of his hand, so any performance differences should become readily apparent. We equipped the cars with our Racelogic DriftBox data acquisition unit to capture lap times and performance data.

| Lap 2 | 54.30 | 52.40 |
| Lap 3 | 53.90 | 52.50 |

| Difference | 1.50 faster |
First, Mike made a baseline run on the original Eagle F1 Supercar EMT, starting with 2 warm up laps followed by a tight group of 4 timed laps, averaging 54.25 seconds with a fastest lap of 53.90. Switching to the Eagle F1 Super Car G: 2 RunOnFlat he again warmed the tires and then put in another group of 4 test laps. In his first ever hot laps on the new generation tire, Mike’s 4-lap average was 52.65 seconds with a fast lap of 52.40, or 1.50 seconds faster than the original Eagle F1 Supercar EMT. Wow!
A look at the data from the fastest lap on each tire shows where the new tire’s performance comes from. The graph’s red trace of the Eagle F1 Supercar G: 2 RunOnFlat is always beyond the trace of the original Eagle F1 Supercar EMT shown in black. With the Eagle F1 Supercar G: 2 RunOnFlat Mike was able to accelerate sooner, brake a little later and carry more speed through the corners at every turn and down each straight.
The original Eagle F1 Supercar EMT showed it’s still a good design for the Corvette and will continue to be used by Chevrolet as the Original Equipment tire for performance handling package cars. The new Eagle F1 Supercar G: 2 RunOnFlat raises the bar, and will initially be available in limited sizes for key applications. In the rarified air of modern supercars, Goodyear’s new Eagle F1 Supercar G: 2 RunOnFlat breathes easily, showing just why Goodyear chose to call this tire "supercar." It really is the next generation super tire for today’s supercars.

Feedback consistently shows the Goodyear Eagle F1 Supercar EMT excels in dry traction, with many scores in the 9-10 range for strong grip and responsive handling. However, wet performance receives mixed feedback, with lower ratings (often 3-6) highlighting reduced confidence in rain and hydroplaning concerns. Ride comfort and noise levels are noted as trade-offs, with some users finding the tire harsh or louder than expected. Treadwear scores vary widely, with several reports of rapid wear conflicting with others citing acceptable longevity for a max performance summer tire. Dry-focused drivers praise its capabilities, while wet-weather use reveals limitations aligned with its summer-focused design.
