I think that's a relic of the white wall and black wall rubber being injected into the tire mold. It might be similar to sprues left on a metal casting. I'd contact Coker to confirm, and if it's only that, then singe them off with a propane torch.
those look like wires from the steel belts. How many years old are those tires? It is common knowledge these days that radial tires expire at about 6 years
Looking at this again, something seems wrong. The tire has some wear on it, so how can the "hairs" not be worn or ground off? Unlikely the tire would have been mounted by a shop looking like that. Maybe it was parked or ran over some bristly material that stuck into it? Note that a couple of the bristles appear to go into a tread block, come out into the air and then go in to the rubber again. I'm revising my guess to post manufacturing damage.
Hard to tell from the picture. I’ve looked at thousands of tires in my past career, but this needs more facts. Are those threads steel or polyester? What is the issue on the other side of the tread? Same or different? Is it the remains of a belt or body ply separation or an impact with something? The tire needs to come off the wheel and the inside inspected at that spot. Too soon to throw stones at Coker. YOMV
Both my Chevy and Buick runs on wheels witout safety beads, i have never used tubes, all advise ive heard, never use tubes in tubeless tires. One advise, wheels without safety beads, keep an eye at the pressure, if running with too low pressure you can shoot the tire from the rim going down the road, I know........
marlin mustang, I am so glad you posted those pictures, that is very similar to the issue I had with my Coker tires. The outer edges of all four tires were worn off as if I had a severe under inflation issue, even though I kept the psi at the recommended 35 psi. I upped the pressure to 40, 45 and then 50 psi and it was like driving on steel tires. Had the car aligned twice and it was spot on both times and the edges of the tires keep wearing off. Next, a tennis ball size bubble appeared on the driver side front whitewall, all this was in less than 13,000 miles! I took pictures of all four tires and showed the Coker people when I was at HERSHEY and was told that they could do nothing for me and this is the God's honest truth, I was told "Coker tires are for show cars and not drivers". I replaced all four tires with B.F.Goodrich wide white tires and at 40,000 miles they show virtually zero wear, proving that is was defective tires!
