Wet roads severely diminish the traction because of <a href="/wiki/Aquaplaning" title="Aquaplaning">aquaplaning</a> due to water trapped between the tyre contact area and the road surface.

Modern day slick tyres have now developed particular performance qualities in a specific window of temperatures, becoming sticky when accumulating enough heat, and thus give much greater adhesion to the road surface,<sup id="cite_ref-racecar-engineering_6-1" class="reference"><a href="#cite_note-racecar-engineering-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> but they also have lower <a href="/wiki/Treadwear_rating" class="mw-redirect" title="Treadwear rating">treadwear ratings</a>; <i>i.e.</i> they wear out much more quickly than the harder rubber tyres used for driving on the streets.

It was the only company in the world that produced and sold original drag racing tyres. </p><p>Drag racing slicks vary in size, from slicks used on motorcycles to very wide ones used on "top fuel" dragsters. For "closed wheel" cars, often the car must be modified merely to account for the size of the slick, raising the body on the rear springs for the height of narrower slicks, or replacing the rear wheel housings with very wide "tubs" and narrowing the <a href="/wiki/Rear_axle" class="mw-redirect" title="Rear axle">rear axle</a> to allow room for the wider varieties of tyres. Open-wheel dragsters are freed from any such constraints, and can go to enormous tyre sizes. Some use very low pressures to maximize the tread contact area, producing the typical sidewall appearance which leads to their being termed "wrinkle wall" slicks. <a href="/wiki/Inner_tube" title="Inner tube">Inner tubes</a> are typically used, to ensure that the air does not suddenly leak catastrophically as the tyre deforms under the stress of launching. </p><p>"Wrinkle Wall" slicks are now specifically designed for the special requirements of drag racing, being constructed in such a way as to allow the sidewall to be twisted by the torque applied at launch, softening the initial start and thus reducing the chances of breaking traction. As speed builds, the <a href="/wiki/Centrifugal_force_(fictitious)" class="mw-redirect" title="Centrifugal force (fictitious)">centrifugal force</a> generated by the tyre's rotation "unwraps" the sidewall, returning the energy to the car's acceleration. Additionally, it causes the tyres to expand radially, increasing their diameter and effectively creating a taller <a href="/wiki/Gear_ratio" class="mw-redirect" title="Gear ratio">gear ratio</a>, allowing a higher top speed with the same <a href="/wiki/Transmission_(mechanics)" class="mw-redirect" title="Transmission (mechanics)">transmission</a> gearing. </p> <div class="mw-heading mw-heading3"><h3 id="Cheater_slicks">Cheater slicks</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Racing_slick&action=edit&section=3" title="Edit section: Cheater slicks"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Since completely slick tyres are outlawed on most roads due to their inability to handle wet pavement, the "cheater slick" became a popular item in the <a href="/wiki/Hot_rod" title="Hot rod">hot rod</a> world in the 1960s; a typical slick type tyre, but engraved with the absolute minimum amount of tread grooves required to satisfy legal requirements. Since then, however, tyre development has progressed greatly, so that today's hot rod street cars typically use wide, grooved tyres which perform better than the slicks of the past; while the cheater slicks available today, both for nostalgic appearance of street cars and for competition use in classes where legal street tyres are required, have followed their own line of development, diverging from true slick tyre construction to become a distinct tyre design in themselves. </p> <div class="mw-heading mw-heading2"><h2 id="R_compound_tyres_(grooved_slicks)"><span id="R_compound_tyres_.28grooved_slicks.29"></span>R compound tyres (grooved slicks)</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Racing_slick&action=edit&section=4" title="Edit section: R compound tyres (grooved slicks)"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The development in cheaper slick technology has affected the development of tyres for racing series other than drag racing as well. When other forms of auto racing similarly instituted classes which require DOT approved street tyres, some manufacturers similarly began to market tyres which superficially resembled their high performance street tyres, but with the least tread pattern permissible and with very soft, sticky rubber, intended specifically for competition because the soft tread would wear too quickly for street use. These became known as <i>R compound tyres</i>. With additional years of progress, this class of tyre has followed its own line of development, to the point where they have little in common with true street tyres of the same brand. This has led to new classes of racing which require not only DOT approval, but also a minimum <a href="/wiki/Treadwear_rating" class="mw-redirect" title="Treadwear rating">treadwear rating</a>, in an effort to eliminate the R compound tyres from competition and require "true" street tyres. </p> <div class="mw-heading mw-heading2"><h2 id="Formula_One">Formula One</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Racing_slick&action=edit&section=5" title="Edit section: Formula One"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Used_slick_tyres_Austrian_GP_2016.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/2/2d/Used_slick_tyres_Austrian_GP_2016.jpg/220px-Used_slick_tyres_Austrian_GP_2016.jpg" decoding="async" width="220" height="147" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/2/2d/Used_slick_tyres_Austrian_GP_2016.jpg/330px-Used_slick_tyres_Austrian_GP_2016.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/2/2d/Used_slick_tyres_Austrian_GP_2016.jpg/440px-Used_slick_tyres_Austrian_GP_2016.jpg 2x" data-file-width="1920" data-file-height="1280" /></a><figcaption><a href="/wiki/Pirelli" title="Pirelli">Pirelli</a> ultrasoft slick tyres seen at the <a href="/wiki/2016_Austrian_Grand_Prix" title="2016 Austrian Grand Prix">2016 Austrian Grand Prix</a>.

In practice, grooved bicycle tyres do not outperform slick tyres on wet roads. However, many low and medium performance bicycle tyres have substantial tread depth, because the bicycles are designed with off-road excursions in mind: in dirt, gravel or sand, the tread pattern provides significantly improved traction. In addition, high-performance bicycle tyres, although designed for road use only, often have a very fine tread pattern, which appears to provide no difference in performance versus a slick tyre and is only there for marketing purposes and as a tyre-wear indicator. This is clear not only from direct testing of tyres, but also from the fact that the texture of the road is itself coarser than the minimal tread pattern on these tyres.<sup id="cite_ref-sheldon_10-0" class="reference"><a href="#cite_note-sheldon-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> Some grooveless designs have small "holes" or dimples embedded in the tread as a tyre-wear indicator.
