Dunlop SP Sport 9000 DSST
||In order to minimize the the
inconvenience of the inevitable flat tire, Dunlop has been
developing run-flat tire technology since the early 1970s.
Dunlop''s early DENOVO run-flat tires were followed by their
Denloc ultra high performance run-flat tires which were used
as original equipment on the Porsche 959 supercar with its
200 mph top speed. Additionally, Dunlop racing tires
incorporating the Denloc design were used by IMSA GTP and
FIA Group C Class racing cars for North American and
international endurance racing events such as the 24 Hours
of Daytona and 24 Hours of LeMans. The disadvantage of these
earlier systems was that they required the use of unique
wheels which greatly increased the cost of installing a
More recently in Europe, Dunlop has sold ultra high
performance tires which incorporate a new run-flat
technology that is designed to be mounted on current
original equipment and aftermarket wheels. This run-flat
technology is being introduced in the United States by
incorporating it into Dunlop''s flagship "HydroMax"
performance tire, the SP Sport 9000. This new run-flat tire
line currently offers five sizes and has been named the SP
Sport 9000 DSST, with the DSST suffix identifying that it
utilizes Dunlop Self-Supporting Technology.
Designed to continue running for up to 50 miles at speeds up
to 55 mph even after sustaining air pressure losses which
would render conventional tires unusable, SP Sport 9000 DSST
tires allow drivers the convenience of being able to better
choose when and where they will have their tire repaired.
For that matter, when driven straight down the road or on
the highway, SP Sport 9000 DSST tires are so good at masking
the traditional loss-of-air symptoms which accompany a flat
tire, that they require a tire pressure monitoring system to
alert the driver that they have lost air pressure.
