• Toyo Proxes TPT Tires are capable of high performance year-round in both arid and wet climates. The casing design and unidirectional tread pattern work in tandem to provide the grip necessary to comfortably drive upon both wet and dry surfaces while also reducing noise significantly. Toyo's line of Proxes TPT tires are best used as replacements for vehicles with T, H or V speed-rated tires.
  
  

Load Index

• The load index, characterized by a speed symbol, represents a tire's ability to carry a load. A higher number in the index represents a heavier load than a tire can support. The load index varies on the tire size of a particular Toyo Proxes TPT tire.
  
  The Toyo Proxes TPT tire with the lowest load index rating is tire size P185/60 R14, with a rating of 82; it can support up to 1,036 lbs. The Proxes TPT tire with the highest index rating is tire size 235/60 R16 with a rating of 100, capable of supporting up to 1,786 lbs. Load index ratings for Toyo Proxes TPT tires typically fall into a range of 85 to 95.
  
  

Speed Rating

• Speed rating determines the maximum speed a tire can sustain---a general approximation that differs based on the type of vehicle and environmental factors. Usually, a higher speed rating results in better handling. The Toyo Proxes TPT tire series has a speed rating of either V (handles well up to 149 miles per hour), H (up to 130 miles per hour) or T (up to 118 miles per hour).
  
  

Tread Depth

• Tread depth indicates how deep the tread cuts into a tire, and tread depth influences a tire's ability to avoid hydroplaning. Typically, a tread that has worn down to 3 mm indicates a tire in need of replacement. Toyo Proxes TPT tires have a tread depth of either 0.31 or 0.32 inches, depending on tire size.
