The European Tyre and Rim Technical Oraganisation
Inflated tyre dimensions, i ncluding manufacturing
tolerances and growth in service, to be used
by vehicle manufacturers in designing for tyre
clearences.Distorcions of the tyre due to load, lateral
and centrifugal forces are not included.
The linear distance between the outside of the
sidewalls of an inflated tyre including manufacturing
tolerances, tolerances for service growth, elevations
due to labeling (markings), decorations, protective
bands or ribs.
The diameter of an inflated tyre at the outemost
surface of the tread.
The maximum load (kg) a tyre is permited to carry
under specified operating conditions. In the case of
twin-fitted driven wheels, a factor of 1.76 is applied
to the load capacity of a single fitment tyre.
The “cold” presure (kPa) of the fluid with which the
tyre is inflated.
data in this Technical databook are relevant to
ETRTO standards, where futher data can be found.
The section width of a an inflated tyre mounted
on its theoretical rim and indicated in the tyre size
designation.
For riding in mid temperatures and on mid rough
surfaces.
When the weather is warm and the riding surface
rough.
For rainy and cold weather when the riding surface
