You know, this is sad, but I just found this. I know it is probably too late but to answer your question, yes i did run them on the stock wheels. I bought the tires used for a good price. I had to keep less air in them than I would have liked to keep the wear pattern even.

I read on an old thread about you running 305's on your trucks. Did you run those on the stock 16x7 rims?
