The replacement depth is the 1.6 mm legal minimum.<\/p>\n<p>\\[ T_0 - T = 8 - 5.5 = 2.5 \\text{ mm worn over 15,000 miles} \\]<\/p>\n<p>\\[ T - T_{\\min} = 5.5 - 1.6 = 3.9 \\text{ mm of usable tread remaining} \\]<\/p>\n<p>\\[ D_{\\text{left}} = \\frac{3.9}{2.5} \\times 15{,}000 = 23{,}400 \\text{ miles} \\]<\/p>\n<p><strong>Result:<\/strong> about 23,400 miles (\u2248 37,660 km) of driving left before the tread reaches 1.6 mm, with roughly 38,400 miles of total tread life. The average wear rate is 0.167 mm per 1,000 miles.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to Use the Calculator<\/h2>\n<ol>\n<li>Enter the <strong>New tread depth<\/strong> \u2014 the depth your tires had when new. Typical new tires have 8\u201310 mm (10\/32 to 12\/32 in); check the manufacturer's specification if unsure.<\/li>\n<li>Measure your <strong>Current tread depth<\/strong> with a tread depth gauge or a coin, and enter the <em>shallowest<\/em> reading from the most worn tire. Use the same unit for all three depths.<\/li>\n<li>Enter the <strong>Replacement depth<\/strong>. The legal minimum in most countries is 1.6 mm (2\/32 in); many safety experts recommend replacing at 3\u20134 mm, especially for wet conditions.<\/li>\n<li>Enter the <strong>Distance driven<\/strong> on these tires so far, in miles or kilometers \u2014 try to be accurate, since the wear rate is derived from this number.<\/li>\n<li>Read the results: usable tread remaining (in mm and 1\/32 in), the estimated distance until replacement, and your average wear rate.<\/li>\n<\/ol>\n<h2>What Tire Tread Life Means<\/h2>\n<p>Tread depth is what keeps your tires gripping the road. As the tread wears down, the tire loses its ability to channel away water, and braking distances grow \u2014 especially in rain. Below about 3 mm, wet braking performance drops sharply, and at the 1.6 mm legal minimum a tire is considered worn out in most jurisdictions. Estimating remaining tread life helps you plan the expense of a new set of tires instead of being surprised by it.<\/p>\n<p>This calculator works from your own real-world data: how much tread has been consumed over the distance already driven. That makes the estimate far more relevant than a tire's advertised warranty mileage, because it automatically reflects your driving style, vehicle weight, road conditions, and how well the tires have been maintained.<\/p>\n<p>The wear rate is the key number to watch. Most tires wear somewhere between 0.1 and 0.2 mm per 1,000 miles under normal mixed driving. A rate well above that suggests aggressive driving, underinflation, overloading, or a wheel alignment problem. A rate far below it usually means mostly highway miles in gentle conditions.<\/p>\n<p>Interpret the distance estimate as a planning figure, not a guarantee. Tires often wear unevenly \u2014 the calculator uses your shallowest measurement, which is the safe approach \u2014 and wear tends to accelerate in the last months of a tire's life as the rubber gets thinner and hotter.<\/p>\n<h2>Assumptions, Limitations and Tips<\/h2>\n<ul>\n<li><strong>Linear wear is assumed.<\/strong> In reality, wear is slightly faster in hot weather, on rough roads, and as the tire ages. Treat the result as an optimistic upper bound and check the tread again before planning any long trip.<\/li>\n<li><strong>Measure correctly.<\/strong> Always read the shallowest groove across the entire tire, and check all four tires. One worn corner usually points to alignment or suspension issues rather than normal wear \u2014 see the tire size comparison context if you're shopping for replacements.<\/li>\n<li><strong>Age matters too.<\/strong> Even with plenty of tread left, most manufacturers recommend replacing tires after 6\u201310 years because the rubber hardens and cracks with age, regardless of mileage.<\/li>\n<li><strong>Keep pressures right.<\/strong> Underinflated tires wear the edges quickly and consume more fuel \u2014 use the <a href=\"https:\/\/wpcalc.com\/en\/life\/tire-pressure-temperature-calculator\/\">Tire Pressure Temperature Calculator<\/a> to adjust pressure for seasonal temperature changes, and the <a href=\"https:\/\/wpcalc.com\/en\/life\/gas-mileage-calculator\/\">Gas Mileage Calculator<\/a> to see how tire condition affects fuel economy.<\/li>\n<li><strong>Rotate regularly.<\/strong> Rotating tires every 5,000\u20138,000 miles evens out wear between front and rear axles, extending the life of the whole set and making estimates like this one more reliable.<\/li>\n<li><strong>Worn tires affect more than grip.<\/strong> They also increase rolling resistance losses and stopping distance. If you're loading the car for a trip, the <a href=\"https:\/\/wpcalc.com\/en\/life\/vehicle-payload-calculator\/\">Vehicle Payload Calculator<\/a> helps you stay within limits, since overloading accelerates tread wear.<\/li>\n<\/ul>\n<h2>Typical Tread Depth Reference<\/h2>\n<table>\n<thead>\n<tr>\n<th>Condition<\/th>\n<th>Tread depth<\/th>\n<th>Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>New tire<\/td>\n<td>8\u201310 mm (10\/32\u201312\/32 in)<\/td>\n<td>Performance tires may start lower, around 7\u20138 mm<\/td>\n<\/tr>\n<tr>\n<td>Good<\/td>\n<td>5\u20138 mm<\/td>\n<td>Full wet-weather capability<\/td>\n<\/tr>\n<tr>\n<td>Worn, replace soon<\/td>\n<td>3\u20134 mm<\/td>\n<td>Wet braking starts to degrade noticeably<\/td>\n<\/tr>\n<tr>\n<td>Legal minimum<\/td>\n<td>1.6 mm (2\/32 in)<\/td>\n<td>Illegal in most countries; replace immediately<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Estimate how many miles or kilometers your tires have left before they reach the replacement tread depth.
