Description
Whether you’re pushing limits on the track or maximizing grip on the street, tire performance degrades as heat builds up—but the S21’s Enhanced Micro-contact Compound (EMC) maintains consistent grip across rising temperatures, so you stay planted when it matters most. The 3D cross-groove design rigidifies the contact patch for sharper cornering response and better road feedback. You get measurable improvements in dry grip and wear life without compromising wet-weather safety, making this a serious choice for drivers who refuse to compromise.
