…percentage of tire wear by comparing the tire's original, new tread depth in its specs to the remaining tread depth as measured. Note: Incorrect air pressure, vehicle misalignment, loose or worn parts, driving conditions, load, etc, can cause rapid or uneven tire wear. An accurate tread depth gauge…

…tread designs and chemists can develop advanced rubber compounds, it is often the remaining tread depth that is the variable in determining wintertime performance. New Tire Tread Depth Approaching Winter Wear Indicators Approaching Tread Wear Indicators Combines necessary features (tread design,…

…tread depth) is 50% worn. 10/32" original tread depth -2/32" legally worn out tread depth 8/32" of useable tread depth. 8/32" useable tread depth -4/32" measured tread depth worn away 4/32" of remaining tread depth (50% of 8/32") A tire that starts with 10/32" of original tread depth has 12.5% wear…

…Tires? (01:13) How can you tell if you need new tires? Check your tread depth. As a tire wears, its ability to perform is reduced. Especially on wet roads in the spring. The important number is 4/32 . We ll show you how to measure your tires to see if they re ready for the roads...or retirement.…

…some of the weaker bonds between the tread rubber molecules, generating heat. If new Track & Competition DOT tires are initially run too aggressively, too hot or too long, some of the stronger bonds will also be broken, which reduces tire grip and wear. Putting new Track & Competition DOT tires…

…smaller elements or adds additional tread depth (required to enhance wet traction) will increase tread block squirm and reduce dry performance. This means that tires typically provide their worst wet traction and their best dry performance just before they wear out. It's also important to remember…

…tires when they reach approximately 4/32" of remaining tread depth. Use a quarter, not a penny, to measure tread depth. Tire Rack's team proved through testing that insufficient tread depth doubles your stopping distance. Adequate tread reduces hydroplaning and helps prevent accidents. Too little…

…According to most states' laws, tires become legally worn out when they reach 2/32" of remaining tread depth (identified when the tread blocks/ribs wear down to the bars molded across their tread pattern). Tire manufacturer treadwear/mileage warranties specify pro-rated replacement will only be…

…gradually drops by about 20% during the life of a tire as the tread wears from its original molded depth to worn out. This can be attributed to the reduction in tread mass and rubber squirm, as well as subtle hardening of the tread compound during years of service and exposure to the elements.…

…cause a single tire to be replaced for safety reasons, the remaining matching tire on that axle must not exceed 30 percent wear. If the remaining tire has more than 30 percent wear from new, it should also be replaced. Handling inconsistencies may result if this is not done. Initially, new tires do…
