You'll want to check this to be certain, but I'm pretty sure that Honda 15" wheels have a bolt pattern, hub, and offset similar to the MINI so you could use those.
minis have the same bolt pattern (4X100) as alot of cars as stated above. So you should have no problem finding some cheap rims. Check out craigslist frequently.
Not true. I recently purchased from Tirerack a set of Bridgestone Blizzaks mounted on 15" steel wheels, had the set shipped directly to my house and then paid a local garage $20 to remove the summer tires and mount all 4 snow tires. It can be done.
