tires that change shape - again

New tire with retractable studs

from Automotive (1095 articles)

March 15, 2007 We're not sure whether the Qtire is named after Q the
gadget guy of James Bond movie fame, but it would be entirely apt –
the new qtire uses a patented all-weather tire technology for autos
and trucks that enables studs to be extended from the surface of the
tire in snow and ice, yet lie below the tread when not required. The
retractable-stud tires incorporate an air bladder that pushes the
studs out from inside the tire when needed, and deflates so the studs
retract into the tire when not needed. The tires are not entirely
maintenance free - the bladder needs to be refilled with air after
the studs have been deployed around 50 times – not much effort for a
significant improvement in safety.

American states Idaho, Washington, Oregon and Montana are expected to
pass legislation to enable the tires to be used all year round. Q
Tires expects to have the new tires available for next winter.
