G63 AMG 6x6 biggest tire size: stock and lifted
The biggest tire owners run on a Mercedes-Benz G 63 AMG 6×6 at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
It comes with 37-inch tyres on 18-inch beadlocks, and Bring a Trailer trucks show 37×12.50R18 tyres. One owner went up to 38×13.50R18 Toyo Open Country M/Ts, along with KW coilovers. There's no known need for anything bigger.

Lift kits, wheels and tires for the G63 AMG 6x6
Two-piece beadlocks in the factory style, so the truck can run the low pressures it was designed for.
If you want the look without the factory price, there are aftermarket 6×6 conversions of ordinary W463s. They are a different vehicle, so price them as one.
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.
