Bridgestone Firestone North American Tire on Thursday, Jan. 24, introduced the Bridgestone L315, an aggressive-traction on-/off-highway wide base radial engineered for long mileage, superior traction and outstanding flotation.

The L315 is designed for axles carrying extra-heavy loads, such as front-discharge cement mixers with front-wheel or all-wheel drive. The tire also is suited for job situations where superior traction is required, such as on dump trucks, specialty oil-field equipment and other on-/off-highway construction vehicles.

The L315’s lug tread and open shoulder design provide hundreds of biting edges to dig into soft surfaces, promoting superior drive traction in mud and on gravel. The wide base design distributes footprint pressure for added flotation while also allowing higher payload; Bridgestone says the L315 has an “L” load rating, which allows it to carry 12,300 lbs. at 120 PSI.

The L315 has a 30/32-inch tread depth to facilitate long original tread life, as well as tough tread compounds designed to resist cuts, chips, tearing and irregular wear. The enhanced compound is made to fight heat buildup so that the on/off-highway tire can be used at sustained speeds to 65 mph.

To enhance retreadability, the groove walls are angled to help prevent the retaining of stones that could pierce the belt package. Heavy-duty casing construction combats bruises and resists belt penetration for added retreadability, and the tire’s casing is engineered to be retreaded for any axle position, with four full steel belts and an all-steel casing ply.

The L315 wide base tire is available in the 445/65R22.5 size in “L” load range. For more information, call 888-694-0469 or go to
