Product Details

The Continental ProContact GX is a luxury all-season touring tire engineered for performance coupes, sedans, and crossovers. Designed as Original Equipment for sophisticated vehicles, this tire delivers exceptional year-round traction combined with enhanced fuel efficiency and a refined driving experience.

Key Features:

  • Multidirectional tread design provides strong grip and traction in all weather conditions
  • Four circumferential grooves channel water away from the contact patch to resist hydroplaning
  • Computer-tuned tread pattern and grooves minimize road noise for a quiet, comfortable ride
  • Precision steering response and secure cornering capability for confident handling
  • Low rolling resistance construction improves fuel efficiency
  • Dense siping and wide grooves enable reliable performance in light winter conditions
  • Self-Supporting RunFlat (SSR) technology available on select sizes

This tire features a 500AA UTQG rating and H-speed rating (up to 130 mph). The ProContact GX is backed by Continental's Total Confidence Plan, which includes up to 65,000-mile limited tread life warranty, 60-day satisfaction trial, and 3 years of roadside assistance. Not Three Peak Mountain Snowflake certified; recommended for all-season use with light winter conditions only.
