Bridgestone Winter Blizzak LM 50 Unstudded Snow Tires
Bridgestone Blizzak LM 50 are studless snow tires suitable for SUV drivers. The tires come with a higher price tag, but the cost is worthwhile given the run-flat technology.
They are not meant for excessive speed. The tires come with a speed index of Q, meaning the tires should not be used if you drive at speeds in excess of 99 miles per hour.
The Bridgestone Blizzak LM 50 winter tires come in one size: 225/60 R17. The studless snow tires were designed for the Toyota Sienna. Their tread is designed to grip the road for optimal traction while allowing water and slush to exit the tire tread to prevent hydroplaning.
How Run Flat Technology Works
Run flat Bridgestone Blizzak LM 50 tires are designed to hold their shape if the tire is punctured. Using self-supporting design, the tires use a special adhesive that holds the tire to the rim. A heat-resistant cord surrounds the inner tire to help it hold its shape when deflated. Run flat tires use multiple layers of rubber to keep the tire from going completely flat. These features keep the tire from slipping off the rim.
If you do develop a hole while driving, it's important to slow down to speeds of no more than 55 miles per hour and have the tire replaced within 80 miles. After that, the Bridgestone Blizzak LM 50 loses its shape and problems will occur.
The production of run flat tires initially was meant to help out drivers of small sports cars who lacked storage space for a jack and spare tire. The tires have advanced in the years and the technology now exists in all-season, summer and winter tires.
Things to Remember about Bridgestone Blizzak LM 50 Tires
It is never advisable to put snow tires on one axle and all-season tires on the other. You should have four tires with the same tread design to maintain control of your vehicle. Mixing tires can lead to loss of control in inclement weather.
When driving in snow and ice, always leave extra room between your vehicle and the car in front of you. Even with Bridgestone Blizzak LM 50 snow tires your stopping distance will increase. Braking too hard can still cause you to slide. It's important to allow extra room and drive at slower speeds to prevent skids.
