They&rsquo;re round, rubber materials that don&rsquo;t run on electricity or have any sort of wiring.<\/p>\n\n\n\n<p>But if you&rsquo;ve read enough books on auto parts, you&rsquo;ll know that they&rsquo;re more complicated than one might think&#19968;especially the low rolling resistance ones.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tire Basics<\/h2>\n\n\n\n<p>Before we get into an in-depth discussion about low resistance tires, it&rsquo;s important to understand the concept of tires as a whole.<\/p>\n\n\n\n<p>Tires essentially act as shock absorbers whenever a vehicle travels over rough surfaces. They also create traction between the wheels and the road for handling purposes. Here are the parts that let tires perform these functions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire-1024x682.jpg\" alt=\"male mechanic doing inspection on car tire\" class=\"wp-image-98252\" width=\"1024\" height=\"682\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire-1024x682.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire-1536x1024.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire-1200x800.jpg 1200w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2023\/12\/male-mechanic-doing-inspection-on-car-tire.jpg 2000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Tires essentially act as shock absorbers whenever a vehicle travels over rough surfaces.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Tread<\/h3>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/blog\/how-to-check-tire-tread-and-tire-pressure\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"tread\">tread<\/a> is the part of the tire that touches the ground. It has a corresponding depth that indicates the need for a replacement when the tread gets shallow enough.<\/p>\n\n\n\n<p>The tread also has grooves that have deep recesses to separate the tread blocks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Sidewall<\/h3>\n\n\n\n<p>The sidewall is the part that sits between the tread and the wheel. This is where you&rsquo;ll find the tire size and other construction details.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Bead<\/h3>\n\n\n\n<p>The bead serves as the foundation of the tire. It&rsquo;s in the position where the tire grips the inside of the wheel rim.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Body Ply<\/h3>\n\n\n\n<p>The body ply is the main framework of the tire. It&rsquo;s made up of several layers that wrap around the beads under the tread and sidewall rubber.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Belt<\/h3>\n\n\n\n<p>The belt consists of two or more layers that cover the body ply and underside of the tread. It helps stabilize the tread, increase its service life, and improve vehicle handling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Inner Liner<\/h3>\n\n\n\n<p>The inner liner is the soft rubber lining inside the tire that protects the body ply. It also has self-sealing capabilities for small punctures.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Major Splice<\/h3>\n\n\n\n<p>The major splice is the stiffest part of the tire. It&rsquo;s the overlapping point of the body ply, belt, and tread.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Are Low Rolling Resistance Tires?<\/h2>\n\n\n\n<p>Rolling resistance is the effort your vehicle exerts to keep the tires rolling at a constant speed. It&rsquo;s based on the phenomenon called hysteresis, a dynamic lag that results in energy loss whenever the tires roll.<\/p>\n\n\n\n<p>A vehicle in transit puts its tires in a constant rolling state while carrying a load, deforming the treads in the process. Rolling resistance, although it consumes a notable amount of energy, is crucial to vehicle grip (traction) and performance.<\/p>\n\n\n\n<p>If that&rsquo;s the case, what&rsquo;s the point of having low rolling resistance tires?<\/p>\n\n\n\n<p>Tires with low rolling resistance essentially reduce the vehicle&rsquo;s overall energy output when pushing through road surfaces.<\/p>\n\n\n\n<p>Reducing rolling resistance can help the vehicle conserve energy, improving fuel economy. According to the US Energy Information Agency, a 10% reduction in rolling resistance can improve fuel economy by 1 to 2%.<\/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<h2 class=\"wp-block-heading\">What Are the Characteristics of Low Rolling Resistance Tires?<\/h2>\n\n\n\n<p>Low rolling resistance tires have several features that enable them to do their job. They include the following:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Tread Design<\/h3>\n\n\n\n<p>Low rolling resistance tires usually feature a contiguous and connected design that rolls as one unit. Unlike conventional and off-road tires, the tread blocks on low rolling resistance tires don&rsquo;t connect to the road surface individually.<\/p>\n\n\n\n<p>Tire tread composition in low rolling resistance tires has also been modified to become more energy-efficient than before. The tread tends to stay cool even when they&rsquo;re rolling, using up less energy due to minimal heat.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Modified Sidewalls<\/h3>\n\n\n\n<p>The sidewalls on low rolling resistance tires are stiffer than conventional tires to reduce deformation when rolling, helping conserve energy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Altered Contact Patch<\/h3>\n\n\n\n<p>Rolling resistance is to be expected from all tires regardless of their type. This means that they will always consume a certain amount of energy.<\/p>\n\n\n\n<p>In the case of low rolling resistance tires, having a smaller tire footprint or contact patch is one way they&rsquo;re able to conserve energy. Reducing the tire&rsquo;s surface area by making it narrower can produce 40% less rolling resistance compared to regular tires.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reduced Tire Weight<\/h3>\n\n\n\n<p>Low rolling resistance tires are lighter than conventional tires to help improve fuel economy. They share the same principle with losing cargo in the trunk so that the vehicle consumes less fuel while moving.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Are the Disadvantages of Low Rolling Resistance Tires?<\/h2>\n\n\n\n<p>One of the biggest disadvantages of low rolling resistance tires is having less tire traction than regular tires.<\/p>\n\n\n\n<p>Having less tire traction could mean greater stopping distances for a vehicle with low rolling resistance tires. It&rsquo;s also possible for these tires to lose traction when moving over wet or <a href=\"https:\/\/www.carparts.com\/blog\/when-do-roads-get-the-most-slippery-how-to-drive-safely\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"slippery surfaces\">slippery surfaces<\/a>, increasing the risk of accidents.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Do Low Rolling Resistance Tires Wear Out Faster Than Regular Tires?<\/h2>\n\n\n\n<p>Although low rolling resistance tires tend to wear out faster than regular tires, the ultimate tradeoff is that they&rsquo;re generally more fuel-efficient than their counterparts.<\/p>\n\n\n\n<p>According to a report from the US Department of Energy, using low rolling resistance tires can result in a 10% fuel savings impact for many drivers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Which Vehicles Have Low Rolling Resistance Tires?<\/h2>\n\n\n\n<p>Most hybrid and <a href=\"https:\/\/carparts.com\/ev\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" aria-label=\"electric vehicles\">electric vehicles<\/a> are sold with low rolling resistance tires as their stock tires.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Wrapping Up<\/h2>\n\n\n\n<p>Low rolling resistance tires are tires that have minimal contact with the ground when a vehicle is in transit.<\/p>\n\n\n\n<p>Having low rolling resistance means the vehicle doesn&rsquo;t exert too much effort for the wheels to move at a constant speed, which results in improved fuel economy.<\/p>\n\n\n\n<p>However, it&rsquo;s also important to note that low rolling resistance tires wear out faster than regular ones because they&rsquo;re made to be narrower and lighter.<\/p>\n\n\n\n<p>Driving with a set of low rolling resistance tires can also result in greater stopping distances and less traction when driving over wet or slippery roads.<\/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\"> 4<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>At first glance, a set of tires might be the simplest thing you&rsquo;ll find on an average vehicle.
