im interested in getting some pegs for my car. i just want 17's and i looked at the demensions. they are 17x8 rims (boston volvo OEM) and 17x7.5 on ipd. i currently have 17x7 rims. if i were to get a set would it be possible to transfer my 215/45/zr17 onto the pegs? or would new tires be needed? also i have a question about offset. IPD says 38mm but im not sure of the OEM's offset as well as my current offset. i have Mille Miglia Ravia rims, is there a place on the inside of the rim that specifies the offset? because i want to make sure i dont do any rubbing ect.
