TIRE REPAIRS
RETREADING
Benefits:
Tyre retreading means environmental awareness and, above all, cost efficiency, as it gives the tyre a 2nd or even 3rd lease of life. This can save tyre costs of up to 40% and significant quantities of crude oil.
After the tread wears out, the tyre's carcass, which accounts for about 80% of the tyre's value, can be retreaded for another "lease of life".
The performance of a retreaded tyre is comparable to that of a new tyre. Retreaded tyres offer similar ratings in terms of running characteristics, mileage, rolling resistance and safety standards.
Cold retreading:
Cold retreading is a method of retreading that does not rely on the use of a mould. It involves renewing the tyre tread, i.e. the profile, using a prepared vulcanised tread strip. The tread is stuck onto the previously roughened carcass using an unvulcanised layer of bonding rubber. At a temperature of 100 – 120°C, the process of binding together the three components is carried out in an autoclave.
Did you know?
How many times a carcass can be retreaded also depends on the type of tyre:
​
-
LORRY TIRES: 1-3x
-
LIGHT LORRY TIRES: generally 1x
SPECIAL REPAIR
Disposing of damaged tires?
​
This is not always necessary. Tyres of all common tractor models can be made serviceable again by means of special repairs. The following images show in detail how such a repair is carried out.
- Identifying the
rubber damage
- Isolating the damage
- Measuring the extent of the damage and choosing
a patch
- Coating with solution
- Filling the hopper
- Heating the hopper
- Roughing up the inner liner
- Fitting the patch
