Mine are 16's Mini 495 Victory Spoke in gloss black, came with the car. Clean up nice however on the 16's even with the smallest wheel woolie you can't get behind the caliper. Looking to upgrade these soon, watch this space.
Very true about tyre cost, I was going to upgrade to 17's, took 6-8 months of viewing hundreds of wheels (many many times). Finally settled on a set that I thought, they're the ones then someone threw a curveball into the decision. Now under positive discussion on a colour enhancement. Downside is they are 18's only atm.
