Bridgestone Firestone North American Tire now is offering fleets in the United States its new M775 on-/off-highway drive radial, which the company says is a popular tire with logging and oil field service fleets in Canada. Suited for severe-service applications, the aggressive drive delivers good traction and removal mileage while usable at highway speeds to 65 mph, the company says.
The specially designed aggressive block tread and open shoulder design helps digs into soft surfaces — such as mud and snow — for additional traction, while angled block sipes help enhance wet traction by breaking up pocketed water for improved grip on wet surfaces. The M775’s tread, which is more than one full inch deep, features compounds to help combat lug base cracking, a common problem with other ultra-deep drive radials.
To help enhance casing life, M775 uses stone rejector platforms and computer-designed groove shapes to help prevent trapped stones from pushing into the tread grooves and piercing the belt layer, which can damage belts and expose them to rust. The tire also incorporates four steel belts and an all-steel casing so it can be retreaded for any axle position, according to BFNT. Split belt construction helps the casing resist cuts and punctures by enveloping debris, which reduces belt damage for longer tire life and enhanced retreadability, according to the company.
The M775 us available in three sizes: 11R22.5, 12R22.5 and 11R24.5 in “H” load ranges for a total load capacity of more than 24,000 pounds per axle in dual fitments. For more information, go to www.bridgestonetrucktires.com.
