How weird......
I've never seen a tire without them.
My Potenza's had it , my Eagle GS-Z's had it , my Kumho's had it , I just looked outside and my Signet DH-60's have it .
Sure you are looking in the right place?? its VERY close to the edge of the rim.
Also , I'm thinking perhaps that maybe only H and up rated tires may have it on there....
Inflation pressure is more crucial on a performance tire than on a regular Passenger car tire
