Audi has chosen Hankook tyres for original equipment fitment on its Q4 e-tron and Q4 Sportback e-tron models. Both electric vehicles will roll on the Hankook Ventus S1 evo 3 ev tyre in the 20 and 21-inch dimensions.
For the special requirements of electric mobility, Hankook says its engineers have equipped the Ventus S1 evo 3 ev with a double-layer carcass made of a specially developed high-performance fibre. It offers very high stability and ensures a low tare weight of the tyre relative to its size.
Also important is the tread compound used in the Ventus S1 evo 3 ev, which has been adapted to the needs of electric mobility. According to Hankook, its very high drive torques ensure excellent grip in wet and dry conditions, while simultaneously optimising rolling resistance.
In the 20 and 21-inch dimensions for the Audi Q4 e-tron and Audi Q4 Sportback e-tron, an additional steel-based reinforcement is used in the bead area due to the reduced flank height to further increase sidewall rigidity. In addition to ensuring the tyre fits the rim precisely, this also results in a particularly sporty and immediate steering response.
The Hankook Sealguard sealing material used inside the tyres (standard on the Hankook 20 and 21‑inch dimensions for the Audi Q4 e-tron and Audi Q4 Sportback e-tron) automatically seals any punctures of up to 5mm in diameter in the tyre tread surface.
Hankook says its Sealguard offers the advantage of being able to continue the journey without delays, even in the event of a nail puncture, for example. It adds that for vehicles equipped with Sealguard, it is no longer necessary to carry a spare wheel. This provides extra space in the vehicle, saves weight, and eliminates the need for a potentially dangerous roadside wheel change.
In addition to their safety benefits, tyres equipped with Hankook’s Sealguard technology continue to offer the usual comfort, as their basic construction does not differ from tyres without Sealguard.
