Decided to throw my wheel spacers on with the stock 20" all season tires for the winter months. These rims don't have the large recessions on the hub mating surface so the alignment nubs needed to be trimmed off as well as no less than a 25mm (1") spacer on all 4 corners.
Used a dremmel to cut off the nubs but had to switch to an air cut off tool.
New 1" hubcentric spacer mounted to the wheel hub.
These are the tracks milled out on the stock GM wheels and the reason the stock wheel studs need shortened.
