Nokian TSF00041 Hakkapeliitta 01 Studded Winter Tire 235/50R20 104T XL SilentDrive

The Nokian Hakkapeliitta 01 Studded (235/50R20 104T XL SilentDrive) is a studdable winter/snow tire engineered for passenger cars, crossovers, and SUVs — including electric vehicles. Designed for drivers who demand confident, adaptive performance as winter conditions shift between hard ice, packed snow, and milder wet roads, the Hakkapeliitta 01 ships pre-studded and ready for the harshest winter conditions.

Double Action Stud Technology is the defining innovation of this tire. When road temperatures drop to freezing or below, the rubber compound stays firm, locking the studs in an extended position to maximize bite on ice. As temperatures rise and roads become wetter, the compound softens and allows the studs to retract deeper into the tread, optimizing contact patch and significantly reducing road wear and noise. The result is improved ice grip, better wet traction, and a quieter ride — all from one tire that adapts automatically.

Key Features:

• Double Action Stud Technology — studs automatically adapt position based on road temperature for optimal grip in all winter conditions
• Pre-studded and ready to install — no separate studding service required
• SilentDrive technology — reduces stud noise for a more refined winter driving experience
• Aggressive snow shoulder grooves — channel deep snow away from the contact patch for strong off-pavement traction
• Self-locking 3D sipes — interlock under load to stabilize tread blocks, enhancing cornering stability and braking response
• Aramid sidewall reinforcement (18-inch and larger sizes) — protects against sidewall damage and punctures
• EV-compatible — engineered to handle the higher torque and added weight of electric vehicles
• XL (Extra Load) rated — load index 104, rated up to 2,000 lbs per tire
• M+S and 3PMSF certified — meets Mud & Snow and Three-Peak Mountain Snowflake standards
