The Mercedes-Benz SLK-series of compact roadsters included the SLK250; its 1.8L 4-cyl provided plenty of power, with a turbo that was tunable to Sport or Normal mode, and it featured all the Mercedes amenities you’d expect. OEM tires for this make/model would have been Pirelli P Zero or Continental ContiSportContact3.
When it’s time to shop 2015 Mercedes-Benz SLK250 tires, remember that this model is designed for an offset fitment, with different tire sizes in front and rear. We’d suggest premium performance-oriented all-season tires like the Falken Azenis ZE960 A/S, Kumho Ecsta PA51 or Michelin Pilot Sport All Season 4. For really precise handling and cornering, consider summer/ultra-high-performance tires like the Pirelli Cinturato P7 or Nexen N’Fera SU1. Just remember that summer/UHP tires will stiffen and lose traction on colder days; summer/UHP tires shouldn’t be used when temperatures are below 40-45 degrees F.
