3D model of every tire
There are over 900 earthmoving tires (25 inch rim diameter and larger)
in the master database supplied with every subscription. Earthmover generates 3D models of
each tire either fully rendered and shaded or as a wire-frame model, depending on user
settings.
Correct
dimensions
The tire models are drawn to scale per the published dimensions issued
by each tire manufacturer. Instead of referring to the same photograph applied to all
tires of the same series, Earthmover draws a 3D model unique for each tire.
Complete
specifications
Earthmover's full report on a tire specification contains over 130
line items, including 5 different charts. You can display the complete specification set
or select and reorder the lines you want.
No manufacturer publishes all specification categories. Most
information is kept confidential or available only on special request. Earthmover fills
these major information gaps so you can make more effective decisions with its realistic
estimates and tire modeling.
Accurate tread patterns
We developed a proprietary program which unrolls a true, 2D
outline of a tread pattern from a 3D photograph of a tire. The program's estimates of
tread lug to groove ratios were statistically the same as actual for over 50
different tread patterns as reported to us by a major tire manufacturer.
Tread patterns for most tires should therefore be accurate on the
presumption that manufacturer provided tire photographs are correct.
Deflection vs. Load
curves
Earthmover's tire models include development of tire deflection as
a function of tire load for each tire. The models are based upon the principles detailed
in Mechanics of Pneumatic Tires published by the U.S. Department of
Transportation.
Deflection is important to correctly computing rimpull, measuring loaded
machinery heights, and estimating tire contact areas.
Contact Area vs. Load
curves
The tire deflection model allows Earthmover to estimate contact
areas as a function of tire load as well as the resulting ground pressures.
Ground pressures can be compared with road bearing capacities to
determine if any tire sinkage will occur.
Rolling
resistances on any soil
Earthmover uses Real
Earth™ objects which are defined by principals of soil engineering and rock
mechanics. These characteristics allow Earthmover to compute the sinkage, slip, and
resulting rolling resistance of each tire on a wide variety of earthen materials.
Five
Star Rating System
Earthmover includes a
series of tire tests under different loading and speed conditions on different road
surfaces and materials. The estimate of tire life is ranked against other similar tires to
determining a star rating.
The star ratings allow you to quickly determine if a specific tire might be a
candidate for your application. For more information, see our Star Rating web page.
