The new
generation tyre, which is designed for rigid dump trucks, offers up to 20 per cent
more tread life than its predecessor, the Michelin XDR tyre. First introduced
at ConExpo/ConAgg in Las Vegas in March, the XDR2 tyre is available in a 27R49
size. Additional sizes will become available to the market.
?The
XDR tyre is the benchmark on haul trucks in quarries around the world,? says
Luc Minguet, global president of Michelin Earthmover Tyres. ?The XDR2 tyre builds
on that foundation to deliver more productivity, better performance and
unquestioned value, all leading to a lower total cost of tyre operation.?
In
addition to the increased tread life, the XDR2 tyre also delivers up to a 10 per
cent thicker undertread between the protective plies and tread base for better
cut and impact resistance. With a new self-cleaning tread pattern, the XDR2
combines full-depth blocks, a 13 per cent larger central lug (compared to the XDR
tyre) and a new non-directional design to provide increased protection against
aggressions and cut separations. The evolving tread design provides an increased
contact patch as the tyre wears, while sculptured cooling vents help keep
running temperatures low.
The
XDR2 tyre also incorporates Michelin?s C2 technology in the casing to provide
an overall cooler operating temperature to maximise the potential life of the
tyre without compromising operating speed or load carrying capacity.
Compared
to the XDR tyre, the steel protective plies on the XDR2 are 60 per cent
stronger to provide improvement in shielding the tyre against aggressions and separations.
The XDR2 tyre also provides twice the sidewall thickness of the previous
generation to resist cuts and abrasions.
