warranty is excluded due to non-conformity to these Conditions without any direct connection with the manufacturing
process.
Warranty shall thus be excluded particularly in following cases:
failure to adhere to the prescribed inflation, loading (i.e. when tyres are subjected to a higher loading than the maximum
load capacity of the tyre ) or the maximum admissible speed of the tyre (use at higher speeds then prescribed by the
speed index)
use of an unsuitable (including unsuitable dimensions), damaged or imbalanced rim
unsuitable vehicle geometry - double track
damage to tyre when mounting/dismounting or due to improper mounting (dismounting, such as but not limited
to, tyre mounted on an unsuitable position on a vehicle, water or foreign particles captured in the tyre interior when
mounting the tyre, tubeless tyres mounted on tube-type rims without tubes, tube type tyres mounted without tubes,
tyres mounted with old, damaged tubes, or tubes of unsuitable sizes
use of an unsuitable inner tubes or flaps (e.g. old flaps) or valves (e.g. old valves)
damage to tyre resulting from improper operation (i.e. usage of a tyre for a purpose other than prescribed by
manufacturer, abusive driving such as tyre spinning or racing)
improper loading of tyres
uneven wear due to improper technical condition of the vehicle (including, but not limited to, improper suspension or
improper brakes)
mechanical damage to tyre during its use (e.g. riding on damaged road surface; flat tyres, cuts on the outer surface,
impacts, water or foreign particles in tyre interior as a result of mounting), mechanical contact of the tyre with chassis
due to, e.g., unsuitable, including to narrow, mudguards
exposure of tyre to external sources of high temperature and heat
intentional alterations of tyres such as, but not limited to, tread re-grooving or other alterations that could adversely
affect the tyre, e.g. adding sealant materials to the tyre)
tyres that were subject to repair- use of such tyres is on exclusive risk of a person who performed such repair
inflating the tyres with medium other than air or by inert gas
damage to the tyres caused by exposure to oil based substances or to other chemicals and/or aggressive agents (e.g.
propellants, fuels, lubricants, acids, lyes, solvents), by exposure to extreme temperatures (heating bodies, brake drums),
by fire or by vis major events
natural wear, i.e., when tyre wear and tear exceed TWI indicator (usable tread is below 0.8 mm or 1/32 inch), Such tyre
reached the end of its service life, irrespective of its age or distance travelled
tyres with a TWI indicator and homologated according to ECE R75, not worn to the TWI indicator but older than 60
months from the date of manufacturing
tyres damaged during shipment by a shipping company
tyres damaged due to non adherence to the general instructions for tyre use, or due to the following irregularities
wrong direction of rotation
use of road tyres for off-road rides, or in circumstances or on a vehicle not recommended by Trelleborg Wheel Systems

tyres subsequently processed out of factory (coloured sidewalls, coloured lettering on sidewalls, subsequently adhered
labels, etc.)
improper storage of tyres (including tyres damaged during improper storing out of the factory warehouse)
tyres which shake and are worn out more than 10% usable tread depth
second hand tyres
claims relating to minimum distance travelled (as this depends on the conditions of use, driving style, etc.)
claims relating to vehicle economy (e.g. rolling resistance, fuel consumption)
claims relating to frequency of pressure check-ups
