My dad is buying a new doublecab and the dealer has installed the toytec 3 inch coil over lift and bushwacker flares but they said he needs to tell them what rims and tires he wants. He has about 4 diffrent types of XD rims to choose from in 18 inch. What offset and tire size should he go with to fill out the flares and not have any major mods to cut away when they install it. He says the 20's they had on the truck rubbed pretty bad so he said no to the 20's. Thanks for any help.
