{"product_id":"sportnex-ar-1-semi-slick-performance-tire","title":"Sportnex AR-1 Semi-Slick Performance Tire","description":"The Nankang Sportnex AR-1 is a refined track tire designed for enthusiasts focusing on lap time performance. It utilizes a unique semi-slick compound that reaches effective operating temperatures quickly, improving grip on demanding circuits. For sizes 17 inches and above, the tire incorporates a Kevlar lining to enhance stability and consistency during high-speed operation. It features an inner angled pattern to assist with wet-condition drainage and wide center ribs for precise steering performance.\n\nTo ensure optimal performance and longevity, Nankang recommends a 'scrubbing-in' procedure for all new tires, involving a gradual increase in track speed over three to four laps before reaching full capacity. Tire tread temperatures should ideally be monitored between 71°C and 104°C, with an inside-to-outside shoulder delta not exceeding 20°C.\n\nThe AR-1 is E-marked (ECE-30) and carries MSA List 1B approval. Compatibility is specific to certain high-performance vehicles, including 2008-2015 Audi R8 models, 2017-2024 Chevrolet Camaro ZL1 variants, 2015-2020 Ford Mustang Shelby GT350\/GT350R, and various Porsche 911 iterations such as the 2011-2012 Carrera GTS. Please verify specific submodel and trim requirements against your wheel configuration, noting that some applications are limited to specific rim diameter options.","brand":"Nankang","offers":[{"title":"Default Title","offer_id":52663084384568,"sku":"AR1-3053019-102YXL-N","price":751.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687514664.jpg?v=1784323650","url":"https:\/\/store.motormia.co\/products\/sportnex-ar-1-semi-slick-performance-tire","provider":"MOTORMIA","version":"1.0","type":"link"}
