The 750Li is an iteration of BMW’s 7-series of full-size sedans. Powered by a twin-turbo 4.4L V8 for 444 hp, the 750i is a long-wheelbase version. Your 750Li xDrive would have left the factory with Pirelli Cinturato P7 All Season, Bridgestone Potenza S001 or Goodyear Excellence ROF tires as OEM; please remember that the 750Li xDrive uses a staggered fitment with different size tires in front and rear, so be sure of the correct size you need when you shop 2015 BMW 750Li xDrive tires.
Tire sizes for a 750Li xDrive could be 245/45R19, 245/40R20 (front), 275/40R19, 275/35R20 (rear), 245/45R19 or 245/50R18. We’d suggest premium all-season tires like the Pirelli Cinturato P7 All Season, Continental ProContact TX (with 55k mile warranty) and Michelin Pilot Sport All Season 4. For more spirited driving, there are summer and ultra-high-performance tires like the Bridgestone Potenza Sport and Michelin Pilot Sport 4. Just be aware that the softer, sticky, pliable tread compound of summer/UHP tires will stiffen and lose traction in colder weather. Summer/UHP tires shouldn’t be used if temperatures are below 40-45 degrees F.
