General Motors built the Hummer H2 generation with cast aluminum, 17×8.5 factory wheels. With an 8×6.5″ bolt pattern, the rims are compatible with OBS Ford and early 8 lug 3/4 and 1 ton American trucks. However, the center bore does not fit over the 2nd gen Dodge unit bearing hub flange without modification.
To modify the rim, simply open the rim center radius by roughly 1/8″ of an inch, or a total inner diameter increase of about 1/4″.
Factory H2 wheel design is a 7 spoke, cast aluminum 17″ rim with 5″ of back spacing. It opens up the possibility of running late model 17″ Load Range E tires.
Attempted to modify the rim by using a router tool and 2-flute routing bit with carbide inserts. Worked well for routing by hand.
Tires are a 265/70R17 (31″ tall tire) BFG.
