How hard can it be?
Pretty hard, actually. Conventional
wisdom says you can't have fuel economy without giving up some other important performance
factor- like traction or long wear.
And, to a large extent, conventional wisdom is right: Many
radials that cut your fuel bill usually don't last, don't hold the road well or don't
retread the way you're used to.
So Bridgestone applied some unconventional wisdom, borrowing some
of the best tread-saving, fuel-conserving and irregular wear-fighting technologies it has
developed, and combined them into a single tire. The result is a new, long-lasting,
fuel-efficient drive radial, the M720.How can the M720 stretch my fuel dollar?
Two ways, actually. The new M720 starts
with the same, fuel-efficient casing that's inside the revolutionary new R227 steer
radial. This casing is designed to be more efficient and run cooler than conventional
designs.
That means the casing itself contributes to the M720's fuel
efficiency, something few manufacturers have been able to do. Result: The M720 saves fuel
now, and when you retread it.
Secondly, the M720 incorporates the latest in Bridgestone
fuel-saving tread compounds. Applying both of these technologies produces a big
improvement in fuel economy.
In competitive tests, the team of Bridgestone R227 steer radials
and M720 drive radials produced about a 7.5 percent advantage over conventional
radials, and was unbeaten for overall fuel economy by major competitors. |

What's going to make the M720 last longer
than other fuel-efficient tires I've tried?
In this case, three things.
Besides fuel efficiency, the M720's casing also produces a nearly ideal footprint. That
means solid traction, high pulling power, even wear and long tread life.
And, Bridgestone's fuel-efficient tread compound blends
cool-running, low rolling resistance natural rubber and the outstanding wear resistance of
synthetic rubber.
Finally, the M720 is a full 26/32", a deep tread drive
radial, not a shallow skid depth drive like so many of the fuel-efficient tires you've
seen in the past. In fact, it's every bit as deep as Bridgestone's legendary M711 drive
radial.What good
is a slow-wearing tread, if irregular wear makes me pull the tires prematurely?
The secret to even wear is even
footprint pressure. So, to combat irregular wear, the M720 borrows technology from
Bridgestone's current premium drive radial, the M726. Namely, continuous contact shoulder
ribs.
In combination with the new casing design borrowed from the R227,
these shoulder ribs help distribute both weight and torque ? evenly ? across the entire
footprint.
And, because the M720 borrows much of its block design from the
highly successful Bridgestone M711, you get solid traction, while minimizing the
"heel-and-toe" irregular wear problems that plague so many drive radials.
What about traction?
Preliminary
tests indicate that the M720 will pull just as hard as the rest of the Bridgestone drive
tire line. That's better than any fuel-efficient drive Bridgestone has tested, and better
than a lot of conventional drive radials. |
How can I get some?
The 295/75R22.5 version of the M720 is on its way to your dealer now, and the
285/75R24.5 should be available during the last quarter of this year.What kind of performance can I
expect from the M720?
Fuel
economy is a great goal, and Bridgestone believes you shouldn't have to sacrifice mileage,
traction or retreadability to get it. That's why we created the M720.
The M720 should deliver long tread life and superb fuel economy.
That means more profits for you- just what you wanted all along. |
