The 740i was an entry in BMW’s 7-series of full-size sedans. Powered by a 322 hp twin-turbo inline 6, the 740i was available from 2008 on, and is also available in a long-wheelbase model. Your 740Li would have left the factory with Goodyear Eagle LS-2 ROF, Goodyear Excellence ROF and Bridgestone Turanza EL42 tires as OEM; please remember that the 740Li 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 740Li xDrive tires.
Tire sizes for a 740Li could be 245/40R20 245/45R19 (front), 275/35R20, 275/40R19 (rear), or 245/50R18. We’d suggest premium all-season tires like the Pirelli Cinturato P7 All Season, Continental ProContact GX 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.
