My 330i X drive Sportwagon has OEM 18" wheels; the factory run flat Contis are down on the wear bars. Just bolted on the Blizzaks, so there's no rush.
Problem has been curb scuffs; the rims were flush with the Conti's sidewalls, so any slight error tears up a rim....and has. A lot.

Here's what I need:
-Non run flat all seasons offering good handling (all seasons for our frequently rainy weather, and late/early snow, non runflats are an experiment).
-Raised sidewall rib to protect those vulnerable rims. The alternate OEM tires had those raised ribs.
Suggestions?
