it wont as long as it hasnt damaged the steel belt, inner body of the tire, remember, that lug will wear down till the surface of the tire is basically flat, it cant "spread" into the belt area, unless it has already been cut into that far.

 

I see, its brand new too with only little more than 500miles. Not sure if i ran something over, i dont see anything in the crack and i cant even tell how deep. bummer

 

If you can get it road hazard warranteed do it.

The cut may not be into the belts, but water intrusion and reaction with the belting and its adhesion is still possible and even likely.

really? jwog comment made more sense though, if its not cut into the belt the tread on there will be wearing down same as they would with no crack.

 

i used to sipe tires, which is basically cutting into the lugs with a machine to add those cuts to the tread, it adds grip. as long as i didnt cut into the belt area all was good.

here is a video

 

Ima stick a flat metal piece tomorrow to test how deep it is and if its down to the belt level. If it is, is it repairable in a tire shop like a nail in tire?

 

I'd be a whole lot more comfortable about this if the cut doesn't go any deeper than even with the bottoms of the tread grooves and if the slice runs in more or less the same direction as what sipes would be cut in.

Do you have a picture of this cut?

About repairing it . . . doubtful. You can't plug it, and a patch on the inside isn't going to hold it together or exclude the water. If it's in the shoulder you shouldn't even consider repairing it.


Incidentally, I've been aware of siping since the 1960's. I think it might have been called 'micro-siping', though that might have been a business trade name for the procedure.

The cut is about half an inch wide and perpendicular to the tread direction. I stuck a metal in it to measure earlier and compared the height with the protruding tread. The cut is deep but not deep enough to meet the bottom of the tread groove, theres alittle space between about 1-2mm.

 

Clicked on the thread to read about tune shifting patterns (just ordered my CAI & tuner for my '14 A/T Mustang) and I got bands, keyboard commandos and tire damages. Thanks. *sigh*

 

While i was doing my oil change today i looked over all my tires and found half a dozen small nicks and punctures from tiny glass/object. Im guessing this is a trade off when you go for soft compound summer tires.
