Sorry for all thetire and rim questions but this is the two things I really don't know to much about. I'm trying tolearn. The places by mewill try to sell me anything even if it is not what I'm looking for. I Don't have any real 4x4 truck places by me so I come to all of you for the answsers. If I get a 20" rim would a 325x60x20 tire fit on the H3 and have that aggressive offroad look? Or something like a 275x65x20 or would that have to low of a profile. They will be going on these rims... Thanks for everyones help....

 

I wouldn't go ask a 4x4 place if that size will fit....they would laugh at you. anything 35" or less in total outside diameter will fit....will be a disgrace to the hummer brand but will fit.
