Product Details

The Toyo Proxes Sport 2 is an ultra-high performance summer tire engineered for sports cars, performance sedans, and coupes demanding exceptional dry and wet handling. Featuring an advanced silica-based tread compound and an asymmetric tread design, this tire delivers outstanding grip, precise steering response, and confident cornering at speed.

Key Features:

  • Advanced nano-scale silica tread compound provides superior wet and dry traction while reducing rolling resistance
  • Dynamic taper technology in the contact patch enhances cornering stability and steering precision
  • Circumferential grooves and lateral grooves efficiently evacuate water to resist hydroplaning
  • Optimized pitch sequence reduces road noise for a quieter, more comfortable ride
  • Reinforced internal structure with high-strength steel belts and polyester casing for durability and high-speed stability
  • Asymmetric tread pattern balances dry performance with wet weather capability

The Proxes Sport 2 is designed exclusively for summer use and delivers maximum performance in temperatures above 40°F. This tire is ideal for driving enthusiasts seeking track-day capability combined with daily drivability. The 275/40R18 size with 103Y speed rating supports loads up to 1,929 pounds per tire and speeds up to 186 mph.
