4 runner rims on a Tacoma

I have a 03 Tacoma double cab with 16" rims and wanted to replace them with 17" 4Runner limited rims. I found out that the 4runner rims have a offset of 30mm while my Tacoma rims have a offset of 15mm. Does this mean that the rims and tires would stick out past my flares if I install the 4Runner rims? Would changing the offset do any damage to my truck? Did anyone out there replace their Tacoma rims with 4Runner rims?
