2017 Bmw 640i-xdrive Tires

When you shop 2017 BMW 640i xDrive tires, be aware that it uses a staggered fitment with different tire sizes in front and rear. Sizes could include 245/35R20, 245/40R19 (front), 275/30R20, 275/35R19 (rear), 245/45R18 or 245/40R19, so be sure of the correct size you need. For your 640i Gran Coupe, you could go with premium all-season tires like the Pirelli Cinturato P7 All Season, Michelin Primacy MXM4 or Goodyear Assurance ComfortDrive. For more spirited driving, consider summer and ultra-high-performance tires like the Michelin Primacy 3 and Pirelli Cinturato P7.Just be aware that summer and UHP tires get their great cornering and handling from a softer, stickier tread compound that’s designed to be pliable, but will stiffen and lose traction in colder weather. Summer/UHP tires shouldn’t be used if temperatures are below 40-45 degrees F.
