I am now running on Punto OEM Alloys for the past 8 months and 15k kms on my MJD Active. I haven't used any hub centric rings as it is a perfect fit. 98PCD is indeed tough to source and that too with a limited design choice. OEM Alloys are always the best bet IMO. You can check my car with the OEM alloys here http://www.teamfiat.co.in/punto-1-3-mjd/7537-kirans-p-ride-7.html I cannot comment on the tyres as I have been using only Yokohomas since the day I bought my Punto.
