Tyre material designers appear to be successful in obtaining both low
rolling resistance and high wet performance, using precipitated silica
together with solution polymers in tyre treads. There is still a need
to improve rolling resistance further. Again, precipitated silica cou
ld be part of the answer, Compounding with precipitated silicas, parti
cularly of high dispersibility, improves rolling resistance and other
tyre properties of many parts of a tyre, We explain that it could be u
sed there to help to meet new low rolling resistance requirements, not
only in passenger tyres, but also in other tyre lines.
