Safety Factors

a) FKR maintains constant pressure at prescribed value conditions for each type of tyre, thus leading to a substantial improvement of tyre use through:

  • Eliminating loss of pressure, caused by punctures in the above mentioned limits and by tyre porosity;
  • Maintaining an equal pressure in all vehicle tyres, thus the overloading of some tyres to the detriment of others is eliminated;
  • Optimal functioning of steering mechanism, thus obtaining a performant vehicle maneuverability to cornering ( the response to cornering maneuver in case of underpressure, is inadequate, the return to driving in straight line is difficult, leading also to changing vehicle’s gravity center).
  • Assurance of prompt and firm response to braking, through maintenance of the beads in the correct position on the rim.

Failure to comply with recommended tyre pressure shall indirectly lead to premature tyre replacement. Incorrect tyre pressure in motion (under pressure or overpressure) reduces dramatically the lifetime of tyres. The three situations are illustrated below (Picture 1):

Picture 1. Tyre configuration at normal inflation pressure and at incorrect inflation pressure.

The under pressure generates:

  • Rarefaction, separation and detachment of steel belts out of the tyre, culminating with steel belts breakage and tyre corrosion in the side wall, as a result of excessive side wall flexions;
  • Tyre overheating, leading to detachment of the tyre component elements, including the tread;
  • Advanced flattening, leads to tyre contact with the roadway, decline of tread resistance and implicitly, increase of vehicle fuel consumption;
  • Quick abrasion of the tyre shoulder, because in these areas the specific pressure of contact has the highest values;
  • Tyre detachment from the rim, especially at turns;
  • Tyre rotation on the rim, with destruction of beads at sudden brakes.

The loss of tyre pressure frequently occurs due to tyres perforation during movement, as well as due to tyre porosity.
The overpressure generates:

  • The decrease of road grip and fast abrasion of the tread center because tyre flattening and high rigidity determines when they overpass obstacles or differences of level, occurrence of bounces and when re-entering in contact with the road, increased frictions appear;
  • The reduction of shock absorption capacity, reducing comfort during motion.
  • The increase of pressure in cord wires and the appearance of fissures in profile canals;
  • Traction power reduction due to reduced tire contact with the road.

By installing FKR in tyres, two of the main causes of pressure loss, punctures within specified limits and tyre porosities are eliminated, thus ensuring tyre rolling at prescribed pressure, significantly decreasing the influence of destructive factors produced by underpressure.

At the same time, damaging effects of overpressure occurred during hauling time can be substantially diminished through installation of FKR in tyres, which, by its capacity of reducing temperature, shall eliminate the cause of undesired pressure increase, maintaining a corresponding pressure inside the tyres.

b) FKR prevents and solves flats that may occur on the tread area, the number one cause of vehicle immobilization on the roads. This can lead to:

  • Elimination of rolling on flat tyre by 80-95%;
  • Reduction of tyre maintenance cost ;
  • Elimination of stationary times, and loss of profit within this period due to flat tyre ;;
  • Reduction of abrasion/destruction risk of double-cable tyre adjusted to breakdown tyre.

c)FKR cools the tyre, taking over part of the heat developed on the tread area through friction and efficiently dispersing it toward narrower tyre sidewalls. Tyre rolling potential shall be improved through:

  • Reducing explosion risk due to overheating;
  • Diminishing tread detachment risk;
  • Diminishing tyre carcass wear, providing the possibility of its retreading;
  • Reduction of damaging effects of overpressure, that appears as a result of temperature increase.

d)FKR allows stoppage in safe conditions

  • If perforating objects have very big dimensions or a tube rip should occur (a quite frequent situation) then the FKR sealant shall impede the sudden deflation through partial closer of thehole; thus it allows STOPPAGE IN SAFE CONDITIONS.
  • If the cord structure was not major affected, but was produced by objects whose size was larger than the allowable, tyre deflation will not be produce in motion, but slowly in stationary, allowing flat repairing in special designed places for tyres exploitation, without being necessary the field intervention of the intervention team.
  • With tubeless tyres, in the case of rim deterioration, the pressure difference between tyre inner pressure and atmospheric pressure shall transport FKR toward deformation and shall partially clog the created hole, the product doesn’t seal metal (rim) – elastic wall (tyre) and in this case the product allows STOPPAGE IN SAFE CONDITIONS. Subsequently the rim shall be repaired, and the corresponding sealant quantity installed.

e) FKR warns about the existence of some problems

FKR does not cause balance problems at tyres if is corectly installed ( see the section Technical Info/Dynamic balancing). If there are problems of this kind, then the presence of FKR in tyres shall accentuate the existing problem, under the form of vibrations. This represents another safety factor, alerting the driver about a major problem at the tyres, rims or suspensions.
