Cool Tire experts needed. Odd wear pattern on front tires

A few days ago, while I had the car on jack I noticed this odd wear pattern on my front tires. They are Goodyear eagle f1 asymmetric 2, been on the car for around 3 years.

At the middle of the tire, as seen from the pictures, there is a joining of what appears to be 2 different tire compounds. From middle towards the inner side, the rubber is softer, whilst harder from middle towards the outer side.

Apparently at the seaming of the 2 compounds, the wear is not even, causing a small "step" at the softer side. Don't know how else to explain it. Does this appear normal or not?

I have been trying for the past months to tackle a steering wheel vibration between 100-140km/h and I was wondering if this could be the culprit.







The rear tires, have the same seam, but there is no uneven wear. Yes tire pressures are checked weekly and I'm at 2.3 front and 2.5 bar rear.

Front: 225/35/18
Rear: 255/30/18

Actually got a call from Goodyear regarding this. That strip of rubber is done intentionally to help with static electricity dissipation.

SPLICE BAR FOR TIRE TREAD EXTRUSION APPARATUS - A splice bar for a tire tread die designed for providing a narrow strip of electrically conductive rubber extending from a lower under tread to the surface of the outer tread by positioning a slotted chimney block in a the outer tread rubber passage and having a passage between the chimney slot and the under tread rubber passage specially shaped for improving the flow of rubber during extrusion. This passage is essentially straight for guiding a strip-shaped stream of rubber of the under tread to the chimney slot. The passage intersects the rear surface of the splice bar to form a generally rectangular shaped corridor extending from the rear surface to the chimney slot. 04-15-2010
