Not sure however I ran V12's on my LCR for nearly 2 years.
I tracked them twice and they held up exceptionally well to the forces put on them (From a very stiff track ready LCR)
What are the tyre pressures like all round?
Sometimes you can lose pressure/cause damage to the tyre due to damaged wheels
I've never heard of it, if everything looks fine I'd be contacting Hankook Directly!
