I do recall that the tire companies came out with a tire for UPS years ago for the front end. It had a special extra grouve about a half inch from each side. It was to absorbe the turns and wear would be less than the wide flat surface on most tires.

I think the Michelin XZE tires are the ones with the extra wear rib. There is a name for that grouve but I cannot think of the exact nomenclature .

I also think the extra rib is made with a harder wearing compound.

I know the tires have been around for years with the extra ribs. But shit, who am I? Let the guys who buy tires every 6 minths just so they can keep the moths out of their wallet.
