All tires slowly lose their pressure over time due to molecular bleed-through where the air leaves the tire through the rubber.<\/p>\n\n\n\n<p>Leaks can cause your tires to be underinflated or flat. This situation will not only reduce the lifespan of your tires but also affect your vehicle&rsquo;s fuel economy and ride comfort. Learning what causes slow leaks and how to fix them will help make this issue bearable.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Tire Slow Leak?&nbsp;<\/h2>\n\n\n\n<p><strong>A slow tire leak happens when your tire&rsquo;s pressure goes down gradually.&nbsp;<\/strong><\/p>\n\n\n\n<p>Some sources say the tire leak is considered &ldquo;slow&rdquo; if you&rsquo;re only losing 1 to 3 PSI a month but that level of pressure loss is normal. In reality, most vehicle owners consider a tire leak &ldquo;slow&rdquo; if it has to be aired up once a week.<\/p>\n\n\n\n<p>Unlike a big tire puncture that&rsquo;s easy to see, you might not notice any signs that your tire is losing air until it gets underinflated or flat.&nbsp;<\/p>\n\n\n\n<p>Furthermore, a tire will generally look okay just glancing at it even if half the air has leaked out.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"984\" height=\"1024\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/A-leaking-tire-close-look-984x1024.jpg\" alt=\"A leaking tire close look\" class=\"wp-image-82263\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/A-leaking-tire-close-look-984x1024.jpg 984w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/A-leaking-tire-close-look-288x300.jpg 288w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/A-leaking-tire-close-look-768x799.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/A-leaking-tire-close-look-1476x1536.jpg 1476w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/A-leaking-tire-close-look-150x156.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/A-leaking-tire-close-look.jpg 1496w\" sizes=\"(max-width: 984px) 100vw, 984px\"><figcaption class=\"wp-element-caption\">A leaking tire | Image Source: Richard McCuistian<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Causes a Slow Tire Leak?<\/h2>\n\n\n\n<p>It can be challenging to identify the cause of a slow tire leak. Let&rsquo;s look at the different issues that can cause it in detail:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Tire Holes<\/h3>\n\n\n\n<p>One of the possible reasons why your tire is slowly leaking air is a tiny hole or puncture.<\/p>\n\n\n\n<p>As you drive your car, <a href=\"https:\/\/www.carparts.com\/blog\/is-it-safe-to-drive-with-a-nail-in-my-tire\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"nails\">nails<\/a>, shards, and other sharp objects can damage your tire. Since the punctures these objects make are small, you might not notice them at a glance.<\/p>\n\n\n\n<p>Most of these objects can also get stuck on the surface of your tire, allowing only a small amount of air to come out of the puncture.<\/p>\n\n\n\n<p>You shouldn&rsquo;t ignore small punctures even if they only cause your tire to lose a little amount of pressure because the situation can get worse anytime. The sharp object clogging the hole can fall off or damage your tire even more, increasing the air it releases.<\/p>\n\n\n\n<p>New tires are more puncture-resistant than old tires because they have thicker threads. But deep threads can also route the sharp debris into your tire, increasing the risk of tire damage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Normal Wear<\/h3>\n\n\n\n<p>A top-notch all-season tire can last around three to five years. So if your tires are older than that, it&rsquo;s normal for them to exhibit <a href=\"https:\/\/www.carparts.com\/blog\/why-do-new-car-tires-wear-out-so-fast-other-tire-faqs\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"signs of wear\">signs of wear<\/a>.<\/p>\n\n\n\n<p>Some old tires can have cracks, causing air to leak out. If this happens to your tires, you&rsquo;ll have to replace them immediately.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Valve Stem Issues<\/h3>\n\n\n\n<p>Valve stems contain the air inside your tires. They are also crucial for tire pressure because you can put and release air pressure through them. So if one of your tires&rsquo; valve stems doesn&rsquo;t seal properly, it&rsquo;ll cause air to leak.<\/p>\n\n\n\n<p>A typical valve stem has a valve stem core and cap. If the cap falls off, debris can get lodged in the core, causing valve stem problems. It&rsquo;s also possible for your valve stems to become brittle or corroded due to moisture and the elements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Leaks Near the Tire Bead<\/h3>\n\n\n\n<p>A tire bead connects the tire to the rim. The seal between the tire and rim is important for proper inflation. Unfortunately, it&rsquo;s not uncommon for leaks to occur around or near your tire bead.<\/p>\n\n\n\n<p>If you&rsquo;ve recently been involved in a crash, damage in your wheels and wheel rims can cause leaks near the tire bead. Rim corrosion can also cause a similar issue.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tire Pressure Monitoring Systems<\/h2>\n\n\n\n<p>If your ride was manufactured from 2008 onwards, it likely has a <a href=\"https:\/\/www.carparts.com\/blog\/understanding-tpms-how-to-reset-the-tire-pressure-light-more\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"tire pressure monitoring system\">tire pressure monitoring system<\/a> (TPMS). The <a href=\"https:\/\/www.carparts.com\/tire-pressure-monitoring-system\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"TPMS\">TPMS<\/a> has air pressure sensors that are usually attached to the valve stem assembly of each tire.<\/p>\n\n\n\n<p>The TPMS warning light on your dash will illuminate once the system detects that one of your tires needs to be inflated. Inflating your tires to the recommended PSI will usually solve the issue.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"722\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/tire-pressure-monitoring-system-located-in-car-steering-wheel-1024x722.jpg\" alt=\"tire pressure monitoring system located in car steering wheel\" class=\"wp-image-81857\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/tire-pressure-monitoring-system-located-in-car-steering-wheel-1024x722.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/tire-pressure-monitoring-system-located-in-car-steering-wheel-300x212.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/tire-pressure-monitoring-system-located-in-car-steering-wheel-768x542.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/tire-pressure-monitoring-system-located-in-car-steering-wheel-1536x1084.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/tire-pressure-monitoring-system-located-in-car-steering-wheel-150x106.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/tire-pressure-monitoring-system-located-in-car-steering-wheel.jpg 2000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">If your ride was manufactured from 2008 onwards, it likely has a tire pressure monitoring system (TPMS).<\/figcaption><\/figure>\n\n\n\n<p>But if you encounter the TPMS light even after inflating your tires, you might be dealing with a leak.<\/p>\n\n\n\n<p><strong>If the TPMS light in your vehicle doesn&rsquo;t illuminate right after inflating your tires but lights up frequently afterward, no matter how many times you inflate your tires, there&rsquo;s likely air leaking slowly from the tires.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Find a Slow Leak In a Tire<\/h2>\n\n\n\n<p>Here are some ways to identify the location of the tire leak:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Inspect the Tires<\/h3>\n\n\n\n<p>You can find a tire leak by looking for a hissing sound, which is usually a sign that air is being pushed out of your tire. So listen to the sounds around your tire while you <a href=\"https:\/\/www.carparts.com\/blog\/how-to-check-tire-tread-and-tire-pressure\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"inspect it\">inspect it<\/a> to determine where the leak is coming from.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Use Soapy Water<\/h3>\n\n\n\n<p>Minor leaks don&rsquo;t always make a hissing noise. Another way to identify the location of the leak is by spraying a soap and water mixture onto the tire. You&rsquo;ll soon notice bubbles in the area where the leak is.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Contact a Professional<\/h3>\n\n\n\n<p>You can always ask a professional to inspect your ride&rsquo;s tires if you suspect air leaks. A trained mechanic will know how to diagnose the issue and rule out any other problem that might be causing your TPMS light to illuminate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is It Safe to Drive with a Tire Slow Leak?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks-1024x682.jpg\" alt=\"man checking the tire of his car for leaks\" class=\"wp-image-81856\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks-1024x682.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks-1536x1024.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks-1200x800.jpg 1200w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/03\/man-checking-the-tire-of-his-car-for-leaks.jpg 2000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Although it&rsquo;s technically possible to drive your vehicle with a slow leaking tire, it&rsquo;s highly recommended that you don&rsquo;t.<\/figcaption><\/figure>\n\n\n\n<p><strong>No. Although it&rsquo;s technically possible to drive your vehicle with a slow leaking tire, it&rsquo;s highly recommended that you don&rsquo;t.<\/strong><\/p>\n\n\n\n<p>Punctured or worn tires are more likely to blow out, increasing the risk of accidents while on the road. Even if the small leak isn&rsquo;t causing any issues, it can develop into a major leak if you ignore it. So take your ride to an auto repair shop right away if you suspect a leak.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Fix a Tire Leak<\/h2>\n\n\n\n<p>How to fix a leak depends on what&rsquo;s causing it. If it&rsquo;s due to a problem in the rim, a sealant might solve the issue. If you&rsquo;re an experienced automotive DIYer, a &ldquo;plug and patch kit&rdquo; might help. However, it&rsquo;s a different story if components like your valve stem are causing the issue.<\/p>\n\n\n\n<p>Should you have your tires repaired or replaced? It&rsquo;ll be best to consult licensed mechanics to find out. They&rsquo;ll know what to check to know if your tires can still be repaired or if it&rsquo;s time to buy a new one.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 5<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>Slow leaks can come from a puncture in the tire, a valve core issue, or between the tire and the&#8230; <a href=\"https:\/\/www.carparts.com\/blog\/tire-slow-leak-heres-why-it-happens\/\" rel=\"nofollow\">Read More<\/a><\/p>\n","protected":false},"author":4,"featured_media":81859,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[52,3752],"tags":[3705],"ppma_author":[2607,2985],"class_list":{"0":"post-81854","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-diy","8":"category-wheels-and-tires","9":"tag-tire-pressure-monitoring-system","10":"entry"},"acf":{"adrotate_specific_mobile_ad":"","adrotate_specific_desktop_ad":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Tire Slow Leak: Here\u2019s Why It Happens - In The Garage with CarParts.com<\/title>\n<meta name=\"description\" content=\"A small leak in your tire can cause low tire pressure.
