I noticed this when I was detailing my car this weekend. I ordered a new tire but when I went in they said it wasn't necessary to replace. What do you guys think. The tire has less then 4k miles on them.
So after I got the tire replaced I spoke to the service manager and he told me the reason the tech said it's not a big deal is because the damage is on the rim guard and not actually on the sidewall. The depth of the damage is about 1mm which seams to be related to a curb hit/rub. Better safe then sorry and piece of mind...
They are intended to sacrifice themselves in order to protect the tire's internal sidewall structure and the alloy wheels upon which they are mounted or curb rub.
I'll find a spare rim and keep it as a spare :wink3:
