The CLS53 AMG is part of Mercedes-Benz’s CLS class of fastback sedans, equipped with an AMG-hotrodded 429 hp 3.0L inline 6 and the usual AMG performance parts. Michelin Primacy 3, Pirelli Cinturato P7, Pirelli P Zero (PZ4 Luxury) or Continental ProContact GX -SSR tires would have been OEM for this make/model.
When it’s time to shop 2021 Mercedes-Benz CLS53 tires, remember that this model is designed for an offset fitment, with different tire sizes in front and rear. Rear sizes could be 275/30R20 or 275/35R19, fronts could be 245/35R20 or 245/40R19. Check out premium performance-oriented all-season tires like the Goodyear Eagle F1 Asymmetric 5 ROF, Yokohama Advan Sport A/S Plus or Continental ExtremeContact DWS06 Plus, or maybe summer/ultra-high-performance tires like the Yokohama Advan Sport V105 or Kumho Ecsta PS91. Just be mindful that summer/UHP tires use a softer, stickier tread formulation that will stiffen up and lose traction on cold days. Summer/UHP tires shouldn’t be used if temperatures are below 40-45 degrees F.
