W463A G-Wagon (2019+) biggest tire size: stock and lifted
The biggest tire owners run on a Mercedes-Benz G-Class (second generation) at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
We couldn’t verify a firm owner consensus for the 2019-on truck. What is documented: factory G 550 sizes are 275/55R19 and 275/50R20 (about 31 in), Mercedes offered 18-inch all-terrain tires as an option, and a 2.5-inch lift kit is rated for up to 33-inch tires. On earlier Gs, about 32 inches is the commonly cited no-rub ceiling — treat it as a starting point and test-fit at full lock. [TO VERIFY FOR 2019+]

Lift kits, wheels and tires for the W463A G-Wagon (2019+)
A 2.5-inch kit clears 33-inch tires, depending on wheel offset, and Eurowise says it works with AMG Ride Control or adaptive suspension.
Mercedes offered 18-inch all-terrains for a reason: smaller rims and taller sidewalls are the biggest off-road upgrade you can make. Check caliper clearance, especially on G 63s.
Fitment comes from owners and specialists; wheel width, offset, trimming and bump stops change what fits. Check clearance at full lock and full flex before you buy. Some links are affiliate links.
