Description
Goodyear EfficientGrip Performance EV-Spec | 265/40R21 105T XL
“Extended Range, Uncompromised Heavyweight EV Support.”
Managing a massive 265-width footprint on a heavy electric SUV presents a unique challenge: you need extreme load-bearing strength without destroying your battery range. The Goodyear EfficientGrip Performance solves this by combining an Extra Load (XL) 105-rated carcass with their proprietary FuelSaving Technology. By deliberately capping the speed rating at “T” (190 km/h) to match standard EV electronic speed limiters, Goodyear’s engineers were free to utilize a highly specialized, ultra-low rolling resistance compound that actively extends your driving distance per charge.
Key Technical Features:
-
FuelSaving Compound Technology: Engineered with an advanced base rubber matrix that drastically reduces the tyre’s internal energy dissipation. This lowers rolling resistance by up to 18%, which directly translates to extended battery range for your heavy EV on daily commutes.
-
Massive EV Load Support: Electric vehicles carry massive under-floor battery packs. The Extra Load (XL) casing and 105 Load Index guarantee this tyre can effortlessly support up to 925 kg per wheel without flexing, squirming, or overheating during high-speed cornering.
-
ActiveBraking Technology: The tread block design is engineered to expand slightly under heavy braking loads, maximizing the massive 265mm contact patch with the asphalt. This delivers remarkably short stopping distances on both dry roads and during sudden tropical downpours.
-
QuietTread Acoustic Optimization: A wide 21-inch tyre naturally generates more road noise. Goodyear offsets this with an optimized, variable-pitch tread block sequence that actively breaks up harmonic air frequencies, delivering the beautifully silent cabin experience expected in a premium electric vehicle.
