　Featuring an advanced new material called “Sustainable Silica Dispersion Agent” as well as a newly developed asymmetrical tread pattern that optimizes the distribution of rigidity throughout the tread surface, SP SPORT MAXX 060+ not only achieves a major improvement in wear resistance compared to its predecessor (SP SPORT MAXX 050+), but also provides the balanced high performance in terms of high-speed stability, cornering and wet grip that one would expect from DUNLOP’s latest flagship tires. At the same time, the adoption of the natural “Sustainable Silica Dispersion Agent” contributes to a significant decrease in the overall environmental impact of these tires compared with conventional tires.

■Product Features

○New Tread Pattern to Optimize Rigidity Distribution

　In order to provide the high-speed stability and cornering performance that premium vehicles demand, SP SPORT MAXX 060+ features a newly developed asymmetrical tread pattern that optimizes the distribution of rigidity throughout the tread surface. The tread design also takes advantage of a 14% increase in the total area of the tread that is in direct contact with the road compared with its predecessor (SP SPORT MAXX 050+) in combination with high-rigidity bands that incorporate aramid (which is also used in bulletproof vests) in order to enhance overall tread rigidity and so ensure a more stable drive. In addition, further enhancing the rigidity of blocks on the outer side of the tread ensures stronger grip when cornering. At the same time, SP SPORT MAXX 060+ also features wider grooves while maintaining a high land ratio*, as well as optimized groove arrangement and contact patch form factor, in order to enhance performance on wet road surfaces.

*The land ratio of a tire tread is a figure indicating the proportion of the tread surface that is not occupied by grooves (i.e. the proportion of the tread that is occupied by blocks and ribs).


○New Compound to Enhance Silica Dispersion

　SP SPORT MAXX 060+ adopts “Sustainable Silica Dispersion Agent,” a new, natural material developed especially for our SP SPORT MAXX Series by Lion Specialty Chemicals Co., Ltd. This material readily forms bonds with both rubber (which is hydrophobic) and silica (which is hydrophilic), which allows for stronger bonding between rubber and silica while also preventing the clustering of silica particles. This in turn allows for an increase in the overall amount of silica (which improves performance on wet road surfaces) included in rubber compounds in order to provide superior performance in terms of both wet grip and wear resistance.


○Luxurious Design Fit for Premium Vehicles

　In order to create a heightened sense of luxury fit for the refined sensibilities of luxury vehicles while also leaving an undeniable impression on the beholder, SP SPORT MAXX 060+ displays the brand logo and product name in breathtaking black on the tire sidewall thanks to a new proprietary design technique called Nano Black*. This innovative technique uses newly developed engraving technology to add tiny bumps and dimples to the sidewall surface in order to suppress the reflection of light, thus producing much deeper, more vivid shades of black than anything seen on tires before. Thanks to Nano Black, the logo and other design elements not only catch the eye, but can also be seen clearly when viewed from any angle.

■Size List

L: EXTRA LOAD Standard (i.e. Enhanced Load Capacity)

About the EXTRA LOAD Standard: This standard designates tires that are designed for higher pressure and load capacity than tires of the same size designed to other standards (JATMA, ETRTO, etc.). As such, EXTRA LOAD tires have a higher load index than other tires of the same size. In addition, in order to maintain this increased load capacity, EXTRA LOAD tires may also require higher internal pressure than other tires of the same size. Sumitomo Rubber Industries, Ltd. offers an extensive lineup of EXTRA LOAD tires in order to meet the needs of larger vehicles produced by international automobile manufacturers.
