Why mercedes wheels with same bolt pattern not fit to another mercedes? I buy AMG wheels from C280 with 5x112 pattern and same 66.5mm hub but i cant install on my '85 SL 380. There is any way to put those in, or i have to sell im back?
Most likely your wheels are hitting the tierod or the tires are hitting the wheel well due to the offset being too high. If you had done a little research on wheel fitment, you'd probably know that offset is pretty important, be it just the PCD and centerbore. I wouldn't recommend going to the expense of getting spacers or adapters, but that could work.
Also, take note that different wheel bolts were used on different cars, and the wheel bolts for 12x1.5 probably isn't going to fit correctly in a wheel that was designed for 14x1.5.
