The boxy, functional Mercedes-Benz G63 SUV went to the AMG shop and came back with a 577 hp V8, tightened-up suspension, 4MATIC and the usual AMG hotrod-Benz goodies. Dunlop SP Sport Maxx, Pirelli Scorpion ATR or Pirelli Scorpion Zero Asimmetrico tires would have been OEM for this make/model. Tire sizes could be 275/50R20, 285/45R21 or 295/40R22.
When it’s time to shop 2019 Mercedes-Benz G3 AMG tires, we’d suggest summer/ultra-high-performance tires like the Falken Azenis FK510, Yokohama Advan ST and Pirelli P Zero (PZ4 Sport). 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; that’s when it’s time to switch to performance-oriented all-season tires like the Bridgestone Alenza Sport A/S MOE or Yokohama Advan Sport A/S Plus (with 50k mile treadwear warranty).
