Volkswagen Polo Service & Repair Manual: Run-Flat Tire, Seal Inside-Technology
| The vehicle can be equipped with run-flat tires as an
option. |
| The Seal Inside technology is a system that allows the
vehicle to continue driving even if the tire has been punctured
by a nail or screw: a protective coating on the inside of the
tire automatically seals any holes caused by a screw or a nail. |
| This way no air can escape. The sealant can work on almost
all types of leaks, that result from objects with a diameter of
up to 5 millimeters. |
 Note
| It is not recommended to use a mix of different tire types
i.e. run-flat and “normal” tires. |
| The seal inside technology has already been incorporated by
the tire manufacturer into the tire manufacturing process. |
| The seal inside technology is a self-adhering, viscous
sealant, which is evenly applied to the inner side of the
running surface from shoulder to shoulder. |
| The sealant is an integral component of mobility tires. |
| There is a special logo on the side wall of the tire which
identifies it as a mobility tire. |
|
|
|
| Example: the sidewall of a Continental tire |
Caution
| The sealant is not intended to be a permanent tire
repair after a puncture has happened. |
|
|
|
|
| If a foreign object with a diameter up to 5 mm punctures the
running surface of a mobility tire, the sealant immediately
closes the puncture and seals it to prevent air leakage. |
|
|
|
| The sealant is designed to seal most punctures caused by a
foreign object, which has a diameter up to 5 mm. |
| The Seal Inside technology reduces the frequency of flat
tires, but it is not intended to make is possible to drive on a
tire which has minimum tire pressure or is completely flat. |
| Mobility tires have all the same characteristics as tires
without the Seal Inside technology. |
| When working with mobility tires it is especially important
to pay attention to cleanliness and to how the tires are stored. |
| The sealant in the inner side of the tire running surface is
not protected and therefore is subject to any type of dirt. |
| It is recommended to store the tires in large bags or
something similar. |
| As with other tires, the mobility tires should be checked
regularly for signs of cuts, punctures and air pressure loss. |
| The tires should be inspected at least one or twice a month
and/or always after a long trip. |
| If punctures or damage are not taken care of in a timely
manner, the result may be a loss of pressure and/or the tire
could fail. |
| Mobility tires with cuts or punctures must be immediately
inspected. |
| It must be decided if the tire should be removed and
scrapped. |
| Mounting and dismounting a mobility tire is identical to
that of a standard tire. |
