NEXEN Roadian HP is a high-speed summer tyre with a directional, symmetrical tread pattern that provides a high level of handling both in a straight line and around corners. The model is designed to fit a wide range of crossovers and offers increased comfort.
Distinctive Features
The addition of silica reduces viscosity and improves the workability and dispersion of the final rubber compound of the tyre tread. The use of environmentally friendly recycled oil together with natural palm oil in the production process enhances the compatibility properties of the polymer and silica.
The NEXEN Roadian HP tyre has a double shielding layer across its entire width in the tread area, which contributes to stiffness and provides steering stability when driving at high speeds. The use of a high-stiffness filler cord increases bead strength and improves handling characteristics. A protective edge on the tyre sidewall reduces the chance of tearing the carcass cord and protects the rim from damage when hiting an obstacle.
The symmetrical, directional V shaped design and the use of silica (silicon dioxide) in the tread compound provide improved grip on all types of road surfaces. Large blocks in the shoulder zone, along with excellent drainage properties of the directional pattern, reduce the risk of aquaplaning and improve braking performance and wet handling.
Optimized block sizes and an evenly spaced 5 step tread pattern reduce noise generation and enhance acoustic comfort.
EU Tyre Label and Efficiency Classes
The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.
Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.
The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.
With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.
Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.
Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.

19.08.2015 from PJM Car considerably more twitchy and lively at motorway speeds than the Continentals that these replaced. Requires continuous corrections.
31.08.2012 from Charles At 50mph the tires had a vibration to them even with multiple balance and rotations done to them but had awesome traction around corners at high speeds
26.04.2012 from keith excellent tyre no problems at all dont get much snow so cant report
27.11.2011 from Tranpus Jones Great looking tires on my truck, Great tread life so far. But the road noise and roughness of ride are acceptable for the price.
