235/45R21 101T Goodyear EfficientGrip Performance
Original price was: $450.00.$448.00Current price is: $448.00.
The Goodyear EfficientGrip Performance in size 235/45R21 101T XL is a premium, high-efficiency summer touring tyre heavily optimized for modern Electric Vehicles (EVs) and eco-focused crossovers.
The unusually low T speed rating (up to 190 km/h) on a massive 21-inch wheel is a highly specific engineering choice: it perfectly aligns with the electronic speed limiters of modern EVs while allowing Goodyear to utilize a specialized, ultra-low rolling resistance compound that wouldn’t survive higher sports-tyre speed ratings. In Singapore, this specific configuration is a definitive factory-style replacement for premium EVs like the Audi Q4 e-tron, Volkswagen ID.4, and Mercedes-Benz EQC.

Description
Goodyear EfficientGrip Performance (235/45R21 101T XL)
“Maximum EV Efficiency, Premium Touring Comfort.”
Electric vehicles demand tyres that can handle extreme battery weight without sacrificing range. Goodyear addresses this by combining an Extra Load (XL) carcass with their proprietary FuelSaving Technology, creating a tyre that supports heavy EV platforms while actively extending your driving distance per charge.

✨ Key Technical Features
-
🔋 FuelSaving Compound Technology:
Engineered with an advanced base compound 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 EV on daily commutes.
-
🛑 ActiveBraking Technology:
The tread block design expands slightly under heavy braking loads, increasing the contact patch with the asphalt. This delivers remarkably short stopping distances on both dry roads and during sudden tropical downpours.
-
💪 Heavy-Duty EV Load Support:
Despite its focus on low drag, the 101 XL rating ensures the internal casing is stiff enough to effortlessly carry the static weight of heavy under-floor battery packs without causing the tyre to flex or overheat during cornering.
-
🔇 Acoustic Comfort & WearControl:
Optimized for a highly uniform wear pattern to prevent the rapid shoulder scrubbing common in high-torque EVs. Additionally, the tread sequence is tuned to minimize road roar, ensuring the silent cabin experience expected in an electric vehicle.
📊 Performance Summary
-
Range Extension & Efficiency: ⭐⭐⭐⭐⭐ (Class-leading low rolling resistance)
-
Cabin Silence & Refinement: ⭐⭐⭐⭐⭐ (Exceptionally quiet touring profile)
-
Wet Weather Braking Safety: ⭐⭐⭐⭐ (Dependable grip via ActiveBraking blocks)
-
High-Speed Track Dynamics: ⭐⭐⭐ (Intentionally capped at 190km/h; optimized for efficiency, not track days)
The Goodyear EfficientGrip Performance is the ideal choice if you prioritize maximizing the driving range of your 21-inch equipped electric vehicle, alongside securing a comfortable, whisper-quiet daily commute.
