G63 AMG (W463) biggest tire size: stock and lifted
The biggest tire owners run on a Mercedes-Benz G 63 AMG at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
About 32 inches, on 20-inch wheels. An Expedition Portal owner runs 275/55R20 (about 32 in) on an unlifted G 63, and another 2017 G 63 owner was told by his dealer the size 'will work fine'. Most unlifted W463s fit 33-inch 275/70R18s, but one Expedition Portal member says 18-inch wheels 'will not fit on the G63' over its big front calipers, so try a wheel on the hub before you buy a set. Recode the tyre size so the speedometer and ESP stay accurate.

Lift kits, wheels and tires for the G63 AMG (W463)
Taller, narrower all-terrains on 20s, or smaller wheels that have been test-fitted over the brakes. This is the biggest off-road improvement for a G 63.
A 60–100 mm spring lift with matched dampers makes room for 33–35-inch tyres and controls a heavy V8 nose.
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.
