BMW 5 Series or Mercedes-Benz E-Class? Both options are excellent vehicles, but we've seen a spike in drivers going the E-Class route.

Have you just picked up an E-Class Sedan, Coupe or Cabriolet? If so, and you live in the Snowbelt region, your E-Class is going to need to be equipped with a set of dedicated winter / snow tires. Given the wide variety of E-Class drivers, both Studless Ice and Snow and Performance Winter / Snow tires may be appropriate. Take a look at "Which Winter Performance Category is Right for You?" to see which winter tire is appropriate for how and where you drive.
Winter / Snow Tire Size
Depending on your exact model, Original Equipment sizes range between 17" and 19" including staggered (wider rear tire) fitments. An optimum winter size for most E350 drivers is 235/45R17. The heavier E550 excels with a 245/45R17 size. While the large brakes of the E63 require the use of either 18" or 19" wheels. Given the E63's prodigious horsepower and torque, most E63 drivers are best served by 255/40R18 in the front and 285/35R18 in the rear on 18" wheels or 255/35R19 in the front and 285/30R19 in the rear on 19" wheels.
Tire Pressure Monitoring System (TPMS)
The E-Class uses valve-stem-mounted direct TPMS sensors priced at $62* each. You can register the TPMS sensors yourself by following the instructions in the owner's manual. There's no additional cost to install the sensors as part of our free mount and balance.
Winter / Snow Tire & Wheel Package for E350 4MATIC
Since you've selected your E350 4MATIC for ultimate safety in the worst conditions, I recommend 235/45R17 Studless Ice and Snow Bridgestone Blizzak WS70s on 17x8 44mm offset bright silver Sport Edition ST3 wheels at $1440*.
Winter / Snow Tire & Wheel Package for RWD E350
If you're a spirited driver who chose a rear-wheel drive E350 for its emphasis on handling, then the 245/45R17 Performance Winter / Snow Pirelli Winter Sottozero Serie II is a better choice. Four of these tires mounted and balanced on Sport Edition ST3 wheels is currently $1488*.
