My daughter has bought a set of alloy wheels for her Seat Ibiza 1.4 sport coupe, they are Tenzo R wheels and are multifit. The question is, using the 5x112 holes the bolt fits through the wheel okay but the Seat PCD is 5x100 and the bolts only just fit through those holes by about 5mm. Wheels are something I've never really messed with. I think the replacement bolts need to have flat seats instead of radius bolts, correct? The info I do know is the bolts are M14x1.5 Thanks in advance.
