I'm still waiting to see if anyone can confirm if this steel emergency spare on a steel wheel will clear the brakes on a 135i. If it does, I'd be interested in one, but I haven't seen anyone confirm this yet.
In the meantime, I'm going with a can of Green Slime and a small air pump
for my winter non-RFTs.
