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.

California tire rules may shrink budget options and raise costs

California regulators approved replacement-tire efficiency standards to boost energy savings, setting rolling-resistance limits at 9.1 N/kN in 2029 and 7.2 by 2033. While the Energy Commission projects small per-tire cost increases and fuel savings, industry voices warn many budget tires could be phased out, reducing choice and potentially raising prices for everyday drivers. Critics also worry lighter, more efficient tires could affect safety, especially for households already struggling financially.

Pirelli's P Zero Race TLR Tyre Reduces Rolling Resistance by 24%

Pirelli has updated its P Zero Race TLR road bike tyres with a new carcass construction that reduces rolling resistance by 24% for a 28mm tyre compared to the previous generation. The new construction uses aramid fibres to provide improved puncture protection and allows for a thinner, more pliant casing. The tyres are available in black or tan wall options, with sizes ranging from 26mm to 32mm depending on spec. Pirelli will also be introducing 35mm and 40mm-wide tyres later this year.
