I have the 19" 296's on my car and after 10,000 miles didn't have a cracked rim yet. I am changing to Conti ExtremeContact DWS in a day or two and was wondering if anybody had cracked rims without the OE runflats.
My independent tire guy told me that he suspects the runflats' stiff sidewall to absorb impact shocks less efficiently and in combination with a "weaker" rim like the 296 causes cracks.
Any thoughts?
