Offset Of Df03 Wheels Vs. Standard Tamiya Car Wheels?

[SidewaysLS4 0]

I'm wrapping up my DF-03RA Hummer project, and since the thing came together so nicely, I'm thinking of getting a spare set of wheels with some real rubber on them...using some DF03 rims to get the 2.2 size on the 12mm hex and some Schumacher Menace GTR front tires all around for those 'performance' driving situations (keeping the Humvee wheels and tires for when I want the scale appearance back). I dont know if the DF03 rims have the same offset as the Humvee rims and the various 1.9 Tamiya rims...so can someone fill me in? TIA!
