Agreed, it is a gallery of "tire carnage", the tire guys would know best. But pretty sure he got his answer here, it is likely from light rubbing over time. I guess I have never seen "long term" rubbing, most of the time it is caught quick from the smell of burnt tires or the sound or rubbing, and is usually just one solid grove and or rub line.

I would doubt if a replacement would be issued the next question is what to do to fix the issue.

 

this is what it looks like after rubbing, i roll fenders and ive seen many tires like this

 

i am 99.9% sure that you are rubbing, my tires right now look the same except worse.

 

......

 

tires don't crack like that.
tires crack like skin, not a long 1 line.
if you look at the other pictures the owner posted, it's definitely an incision
not a tire defect.

 

from the looks of it, it seems like you do some aggressive driving with these tires.

 

Looks like someone knifed them to me....

 

knifing a tire would be the biggest waste of time. it will take you atleast 30 minutes of slicing away to cut through some inner tire weavings..and there still won't be a hole.

 

trust me he is rubbing ......... (like me&silentdancer said)


look at the plastic piece its coming off because you're rubbing.

 

Same issue just a little worse I need to replace this tire asap, been driving the civic for now. Basically I hit a bad dip hole and I heard it hit/rub the tire, came home and there were the results.
