Dunlop SportMaxx LUX SilentCore-EV | 245/40R21 100W XL (Made in Japan)

“Sovereign Silence. The Peak of Electrified Luxury.”

High-performance electric vehicles and luxury cruisers with large 21-inch wheels face a unique engineering challenge: the massive contact patch generates significant road noise, which is immediately noticeable in the absence of a combustion engine. The brand-new Dunlop SportMaxx LUX SilentCore-EV solves this flawlessly. This state-of-the-art, Japanese-made (JP) tyre is Dunlop’s premium high-performance comfort model, specifically carrying the official “EV Suitable” designation. By integrating high-volume acoustic foam directly into an Extra Load (100) reinforced carcass, this 21-inch configuration transforms your wheels into a source of luxuriously smooth, whisper-quiet cruising while effortlessly handling instantaneous electric torque.

Key Technical Features:

• 🧽 SilentCore Technology (Acoustic Sponge): Inside the large 21-inch tyre cavity sits a specialized, high-volume polyurethane foam layer. This sponge actively absorbs “cavity resonance”—the hollow vibration of air inside wide tyres—slashing low-frequency cabin road noise by nearly 9dB. This delivers a beautifully serene ride that perfectly complements hushed EV powertrains.

• ⚡ EV-Specific Reinforced Carcass: Built to handle the brutal, instantaneous torque of modern electric systems. The high-rigidity internal structure and Extra Load (100) rating safely support up to 800 kg per tyre, managing the immense curb weight of under-floor battery packs without mid-corner sidewall flexing or premature shoulder wear.

• 🌊 Silent Wave Tread Design: A combination of optimized variable-pitch blocks, a “seamless groove” design, and dual slopes interrupts sound waves before they leave the tyre’s contact patch. This intelligent noise reduction technology provides one of the lowest external pass-by noise ratings in its premium class.

• 🏎️ MAXX Drivability Profile: Features a wide, ultra-flat contact patch specifically optimized for heavy applications. This maximizes mechanical grip and steering stability, ensuring the vehicle’s high-torque power is delivered smoothly while providing crisp, responsive turn-in on the front axle.

• 🧪 Next-Generation Modified Polymer: The advanced tread compound significantly reduces internal heat generation as the heavy tyre rolls. Lower heat translates to ultra-low rolling resistance, which directly maximizes your battery range and improves the vehicle’s total energy efficiency.

Perfect Fitment For:

In Singapore, this highly specialized 21-inch configuration is the definitive luxury and ride-refinement upgrade, often serving as the front-axle counterpart to wider rear tyres on high-performance electric crossovers and luxury sedans seeking the absolute quietest ride possible. It is highly recommended for:

• BMW: X3, X4, iX3 (Front-axle fitment for 21-inch staggered setups)

• Audi: A6 e-tron, S6 e-tron (Specific 21-inch setups)

• Lexus: LC 500, LC 500h (Alternative front-axle touring/comfort setups)
