Goodyear KMAX D
Goodyear KMAX D
The KMAX D tire offers high mileage potential, high traction performance and low noise emission thanks to optimized tire pressure distribution, the right number of pitches, the non-skid optimized block geometry and a higher wearable rubber volume compared to its predecessors. The KMAX D tire meets established winter requirements and carries both the M+S and the 3 Peak Mountain Snow Flake symbol.
Up to 35% more mileage compared to its predecessor*. The KMAX D offers high mileage potential, high traction performance and low noise emission thanks to:
- Optimised block geometries
- Directional, V-shape tread pattern
- 3D waffle sipes
- M+S marking
Long V-shape directional tread design Tread blocks gradually contact and leave the road surface -> limits the potential for block slipping.
S-shape 3D waffle sipes and raindrop channel Block parts interconnect as the tyre rolls into its footprint and raindrop channel generates new groove when tyre is 3/4 worn -> limits block movement and block slip -> excellent grip on slippery surface, even when worn.
Special connection bridges between the tread block Individual blocks are interconnected at different tread depths bridges stiffen the tread and -> limit tread movement and block slipping.
The European Union, under CE 1222/2009, has mandated that all tyres manufactured after the date of July 1 2012 for cars and commercial vehicles include standard EU Tyre Labels classifying them by three performance characteristics:fuel efficiency classified from A to G,wet grip classified from A to G, and noise emission in decibels.
Categories of tyres unaffected by this regulation include: retreaded tyres, professional off-road tyres, racing/sports car tyres, as well as certain types of tyres designed to improve traction such as studded tyres, T-type temporary spare tyres, tyres for cars built before 1990, tyres with a maximum allowed speed of 80km/h, tyres for rims with a diameter less or equal to 254 mm or greater or equal to 635 mm.
This label is intended on one hand to promote economic and ecological efficiency in traffic, as well as increase road safety, and on the other hand to help consumers select appropriate tyres by ensuring a certain degree of product transparency.
Nevertheless, the label has been criticized for only showing a very limited number of characteristics. Professionals argue that tyres have many more features that are important and relevant to road safety, including but not limited to aquaplaning properties, driving stability, service life, product properties on wet and dry roads other than wet grip, properties on snow.
Tyre manufacturers suggest that the test results from various institutions and industry magazines should remain a very important source of information for the end consumer, because they focus on and rate a wide variety of tyre properties and features.
