Hankook Ventus S1 evo Z AS X H129A
Choose the Hankook Ventus S1 evo Z AS X H129A when you want year-round confidence with a performance edge. This ultra-high-performance all-season tire delivers precise steering, strong wet braking, and everyday comfort. Its silica-enhanced compound maintains grip across a wide temperature range, and the balanced tread pattern keeps the car settled at highway speeds. Whether you're replacing worn performance tires or an OE-grade fitment, the S1 evo Z AS X H129A provides a composed ride and predictable handling in dry, wet, and light-snow conditions.
Key features
The Ventus S1 evo Z AS X H129A blends performance and practicality for real-world driving. Wide circumferential grooves move water away to cut hydroplaning risk. Solid outer shoulder blocks sharpen turn-in and keep cornering stable, while a silica-rich, cold-weather-capable compound and dense siping help braking as temperatures drop. An optimized contact patch spreads load for more even wear, and tuned pitch sequencing reduces pattern noise for a quieter cabin.
Performance in dry, wet, and light snow
On dry pavement, a stiff shoulder design and continuous center rib deliver direct steering feel and steady on-center tracking. In rain, four main grooves and lateral channels clear water quickly, supporting confident braking and acceleration. When the mercury dips, the all-season blend stays more compliant than a summer compound, and fine sipes add biting edges for light snow traction. For deep snow and prolonged ice, dedicated winter tires remain the safer choice.
Tread design and materials
A directional-inspired tread layout prioritizes stability and water clearance, with wide channels that carry standing water away from the contact patch. Larger, more rigid outer shoulder blocks resist flex in hard corners, while added siping on the inner tread boosts wet grip and light-snow traction. The silica compound improves wet adhesion and helps curb rolling resistance. Reinforced sidewalls support precise responses at speed and during quick transitions, promoting confident handling and even wear.
Sizes, specs, and fitment
Match your tire size, load index, and speed rating to the door-jamb placard or owner's manual. The Ventus S1 evo Z AS X H129A comes in popular performance fitments for sport sedans and coupes. Some sizes carry OE markings or suffixes, such as H129A, which indicate a manufacturer-tuned variant, so keep those codes when replacing OE tires to preserve steering and ride feel. If wheels or suspension are modified, confirm overall diameter and clearance, or contact our fitment team for help.
Pricing and how to buy
Pricing for the Hankook Ventus S1 evo Z AS X H129A varies by size, load and speed rating, and availability. Watch for seasonal promos and installation bundles to stretch your budget. At checkout, add professional mounting, new valve stems, TPMS service, and an alignment to protect tread life and performance. Rotate every 5,000 to 7,500 miles and maintain door-placard pressures, then select your vehicle, confirm the exact size and any OE markings, and choose delivery to your installer or a partner location.
