During a routine tire pressure check, I noticed this gouge in the side of my tire:

I'm wondering if it is a safety issue, but I hesitate to take it to a tire shop because I want an unbiased opinion. It seems to hold the air just fine and it isn't more than a couple mm deep, but I don't want to have a blowout.

That crack was caused by heat and drying out in the sun. It will run, and your should replace the tire.

    Yep, that's one to be replaced sooner rather than later. There may not be much rubber left under there, the sidewalls of tires are quite thin compared to the traction surface. Mar 22, 2012 at 19:00

    If the other tires are all the same age check them all.

Its always good to replace a tire that has any damage done to the side wall.
