Abrasion limits turning tread wear into a compliance property
Regulation now treats tread loss as an emission rather than a durability claim, which removes the compounder's oldest lever. Grip has always been bought by accepting faster wear, and that trade is no longer available at the same terms. Silica and silane systems grow at 7.8% because they improve wet grip and rolling resistance together, though at roughly 30% higher compound cost. Functionalised polymers and resin systems carry the rest of the burden. Suppliers arriving with a grade and a price are answering a tender that somebody else already framed.
