6%
less material. No waste!
Practically speaking, with the saved
material you can retread 1 extra tire every
16 and a half tires.With today high material costs very
solid advantage, don't you think?
You may ask, how is it possible to
estimate this saving in such an exact way? Saving
is not a matter of opinion: let's calculate it together.
Compared to a regular conventional tread the material-savings
obtained with RINGTREAD System comes from four factors,
each one of them corresponds to a precise saving
percentage:
- no
waste 2%: tread ends become oxidized and
must be thrown away.
- concave
pressing 1%: the flat tread circumference
is always the same, while in the RING it decreases
near the shoulders.
- guaranteed
and uniform stretch 1%: conventional
tread cannot be stretched in the splice area.
- smaller
average undertread 2%: thanks to radial
pressing the RINGTREAD undertread is uniform
on all its base surface.
The resulting sum gives a total minimum saving of 6%.
