Vehicles Used
2012 BMW F30 328i Sedan
Max Performance Summer tires are capable of delivering an unsurpassed blend of dry and wet traction and handling for
the street using high-tech materials and advanced manufacturing techniques. The performance of these summer, or
three-season, tires isn’t hampered by the inherent compromises of all-season tires that have to also cope with
winter weather. For many driving enthusiasts, Max Performance tires connect the soul of their sporty coupe or sedan
to the road, translating driver commands into action. And unlike more extreme summer tire options, Max Performance
tires also deliver reasonable road manners to keep the daily drive enjoyable.
We wanted to find out how several new Max Performance Summer tires perform out on the road and on our handling
track. Like many of the latest tires in the category the new Dunlop Sport Maxx RT and Yokohama ADVAN Sport V105 both
draw on motorsports technology for their advanced tread compound and other design aspects. We compared the pair with
the top two tires in the category, the Bridgestone Potenza S-04 Pole Position and Michelin Pilot Super Sport. Our
evaluation used 2012 BMW F30 328i sedans fitted with new, full tread depth 245/40R18 tires mounted on 18x8.0 wheels.
What We Learned on the Road
Our 4.1-mile loop of expressway, state highway and county roads provides a great variety of road conditions that
include city and highway speeds, smooth and coarse concrete, as well as new and patched asphalt. This route allows
our team to experience noise comfort, ride quality and everyday handling, just as you would during your drive to
school or work.
You don’t have to be on a racetrack to enjoy the handling of a Max Performance Summer tire. The car just does what
you want, without you having to really think about it. Some might describe the handling as telepathic, but not in
the instantaneous sense. Rather, these tires are like the perfect mate, knowing what you want almost before you do,
creating a sync between driver, car and road that makes piloting the vehicle a true pleasure.
If handling were measured by time, the Michelin Pilot Super Sport would always show up early. This tire is the most
direct and responsive of the group, with instant response as soon as you begin to turn the steering wheel. The
Yokohama ADVAN Sport V105 is a close second, also displaying immediate response and linear steering where you get
exactly as much as you ask for with a turn of the wheel. The Bridgestone Potenza S-04 Pole Position also handles
well with a little slower response than the Michelin and Yokohama tires. And the Dunlop Sport Maxx RT rounds out the
group with a nice feel in the steering wheel.
The ride quality of this group is reasonable, but wouldn’t be confused with the comfortable manners of a touring
tire. Max Performance Summer tires do bring a sense of connection to the road, keeping the driver engaged and
informed about the pavement they’re rolling over. Among the four tires in our test the Potenza S-04 Pole Position
delivers a slightly more confortable ride than the others. The Pilot Super Sport and Sport Maxx RT aren’t too far
behind, both riding well enough, but letting through a little more edge to the sharper and larger impacts. The ADVAN
Sport V105 is by no means harsh riding, but it doesn’t envelop the bumps quite as well as the others.
All four tires produced modest tread and impact noise levels, with the Pilot Super Sport and Potenza S-04 Pole
Position having a small advantage over the others. The ADVAN Sport V105 and Sport Maxx RT were essentially the same,
both with just a little more tread and impact volume than the Michelin and Bridgestone tires.
What We Learned on the Test Track
Our 1/3-mile per lap test track course includes 90-degree street corners, a five-cone slalom and simulated
expressway ramps. Run in both dry and wet conditions, the test track allows our team to experience the traction,
responsiveness, handling and drivability normally only encountered during abrupt emergency avoidance maneuvers or
competition events.
When asking these tires to drive at their limit, the Michelin Pilot Super Sport leads the group. It feels almost
unflappable with impressive lateral grip and responsive steering that build driver confidence. The new Yokohama
ADVAN Sport V105 gives the Pilot Super Sport’s quick lap time a run for its money, trailing the Michelin by less
than half a tenth of a second. But where the Pilot Super Sport feels almost locked down, the ADVAN Sport V105
feels lively with very good overall grip that allows the driver to remain in control as the car dances through
fast transitions. The Sport Maxx RT and Potenza S-04 Pole Position tires didn’t have quite the grip or composure
to match the speed of the leaders.
In wet conditions, the handling balance of the ADVAN Sport V105 and its high overall traction level helped it lap
our course faster than the others. The Pilot Super Sport again showed its stable front-rear balance with gentle
understeer at the limit, which helps avoid surprises when pushing the limit in wet conditions. The Potenza S-04
Pole Position and Sport Maxx RT tires weren’t too far behind, with predictable handling and reasonable overall
grip that was just a notch behind the best in class.
Fuel Consumption Results
Our Real World Road Ride features a relatively flat 4.1-mile loop of 65 mph expressway, 55 mph state highway and
40 mph county roads along with two stop signs and one traffic light every lap. Our team drove each tire
approximately 400 miles over the course of several days. Since we wanted to compare fuel consumption results that
typical drivers would experience, our drivers were instructed to maintain the flow of traffic by running at the
posted speed limits and sustain the vehicle’s speed using cruise control whenever possible. They did not use
hypermiling techniques to influence vehicle fuel economy.

While none of the tires in this test were designed with low rolling resistance as a high priority, we did find a
difference in observed vehicle fuel economy across the group. Based on our results the 0.9 mile per gallon
difference between our lowest and highest observed fuel economy would result in an annual difference of almost 17
gallons of premium gasoline. At the current cost of $4.00/gallon, it would amount to an annual difference of about
$67 for drivers driving 15,000 miles per year.
It’s important to note our test’s fuel consumption measurements follow consistent procedures designed to minimize
variables that could influence the results, however they do not represent an exhaustive long-range fuel
consumption study. While our procedures require the test vehicles in each convoy to run under the same prevailing
conditions, the week-to-week differences in ambient temperatures, barometric pressures and wind speeds that we
experience over a season of testing can influence vehicle fuel consumption and prevent the absolute mpg values of
this test from being compared directly against those of others.
Larger differences in consumption between tires may indicate a difference that might be experienced on the road,
while smaller differences should be considered equivalent. As they say, your mileage may vary.
Summary
For the driver who wants to be engaged in the driving experience, Max Performance Summer tires provide a superior
connection to the road. Among our test group, the Michelin Pilot Super Sport shines, delivering road manners that
you can live with while being very capable when you want to enjoy driving at the limit. The Bridgestone Potenza
S-04 Pole Position isn’t quite as focused on going fast, but still provides a great blend of handling and ride
quality. The Yokohama ADVAN Sport V105 is tuned for the driver who wants responsive handling and track speed to
challenge the Michelin. And the Dunlop Sport Maxx RT rounds out the group with appropriate levels of handling and
acceptable road manners.
