The GLS63 AMG model of the Benz GLS class of full-size luxury SUVs is powered by a twin-turbo, 603 hp 4.0L V8, with standard 4Matic AWD and an optional offroad package.Pirelli Scorpion Zero, Pirelli P Zero or Continental CrossContact UHP tires would have been OEM from the factory for this make/model.
When it’s time to shop 2019 Mercedes-Benz GLS63 AMG tires, tire sizes could be 295/40R21 or 295/40ZR21, so be sure of the correct size you need. We’d recommend summer/ultra-high-performance tires like the Goodyear Eagle F1 Asymmetric 2 or Toyo Celsius Sport, or premium performance-oriented all-season tires like the Pirelli Scorpion Zero All Season, Yokohama Geolandar X-CV or Michelin Pilot Sport All Season 4. If you opt for summer/UHP tires, just remember that summer/UHP tires use a softer, stickier tread formulation that will stiffen and lose traction on colder days. Summer/UHP tires shouldn’t be used when temperatures are below 40-45 degrees F.
