California tire rules spark price warnings from Dunlop

Dunlop Tires warns that California's new replacement tire efficiency rules, which phase in a minimum rolling-resistance standard starting in 2029, will raise manufacturing costs and likely push tire prices higher—estimates range up to $157 per tire, meaning hundreds more per vehicle. The policy, intended to cut emissions and save fuel, has mixed support among manufacturers and could hurt smaller brands, while performance concerns such as grip and durability are also raised.
