Tire repair Riga-Latvia

During operation, car tires do not only wear out. From time to time, tire punctures occur, as well as a variety of damage to the sidewalls: cuts, punctures and just superficial damage not associated with a violation of the tightness of the tire.

Due to the tight and strong contact with curbs, stones and the like, the sidewall receives superficial damage, similar to craters.

Tire repair is a service that even the most careful drivers cannot avoid. Considering our roads, this is a very popular request in tire shops. Statistics say that about half of road traffic adventures are due to car owners’ negligence towards tires. Now we will try to find a solution to the problems and give answers to common questions. And specialists will be able to eliminate the trouble and make you a first-class tire repair.

Tire design

Structurally, tires are tubular and tubeless. Since more modern tubeless tires have become almost ubiquitous, in order to better understand whether tire damage is critical, consider the structure of a tubeless tire.

  • Internal frame, consisting of bead rings and textile threads attached to them. Gives the tire the correct shape and the required rigidity. In diagonal tires, the cords in the carcass intersect, in radial ones they are parallel to each other;
  • A hard rubber bead is required to secure the tire to the rim;
  • The sidewall, made of rubber with a thickness of up to 3 mm, protects the inner frame of the tire from moisture penetration, and the side walls of the tire from impacts and mechanical damage;
  • A tread that makes direct contact with the road surface and provides traction. Consists of the shoulder and central area;
  • The belt layer is located inside the tire and consists of textile and metal rings that separate the carcass and the tread. Serves to form a profile and strengthen the structure of the tire.

Types of tire damage

  1. Puncture is the most common damage resulting in loss of tire tightness. After removing the damaging element, carefully inspect the tire: if the edges of the hole come together tightly and the puncture is almost invisible, the damage is not critical and must be repaired. If the hole is noticeable – most likely, the tire cord layer is damaged.
  2. Break or cut – damage to the cords. Most often occurs when a car hits sharp objects (fittings, glass). Cuts that appear in the shoulder or sidewall of the tire are practically not repairable. Small cuts in the treadmill area of the tire can be patched and hot vulcanized.
  3. Hernia, or swelling of the tire surface. It occurs due to peeling of the tread from the cord, breaking of the threads of the inner carcass. The tire will depressurize, it is difficult to determine the place of damage, repair is difficult.
  4. Violation of geometry. The most common cause is damage to the bead ring or cord. Sometimes such a defect occurs in new tires due to non-compliance with the technology. Improper tire fitting or use of tires can also lead to geometry abnormalities.

Causes of tire damage

Violation of the rules for the operation of rubber:

  • the main cause of tire damage, its characteristics in terms of weight and load may not be correctly selected, our article will help you choose the speed and load index.
  • lack of systematic tire pressure monitoring.
  • Approximately 20% of a tire’s life is lost precisely due to overload or reduced pressure. When choosing tires, we recommend taking into account 15% of the margin according to this criterion, then short-term vehicle overloads will not affect the total mileage of the tire.
  • Improper assembly and disassembly of tires.
  • Wheel balance imbalance.
  • Breakdown of the steering or problems with the chassis of the car.
  • Driving on gravel or crushed stone roads significantly reduces tire mileage
  • Fast and aggressive driving. The tire overheats, the friction from contact with the road surface increases, the tire wears out quickly, and delamination is possible. Rapid acceleration and deceleration also has a negative effect on the overall tire life.
  • And of course the condition of the roads. Every inexperienced driver starts to brake at the sight of an obstacle or a pit, which is good if the car is equipped with an ABS system, but when braking hard, the wheels block, which leads to bumps and a broken cord. It is better to “fly over” this pit than to brake in it, so you will definitely save your tires more.

Types of tire repair

Depending on the size and location of the defect, our specialists can offer several repair options. In the case of the fastest and most inexpensive way, a car service specialist can correctly install the harness. But if the problem is serious, more complex and expensive repairs may be needed in the form of:

Repair method without disassembling the tire. This method is considered temporary and it is recommended to overhaul the tire by removing it from the rim. This method is appropriate on the road, or if there is no spare wheel, or some tool to put the spare wheel. For such repairs, sealants or harnesses, or inserts are used. The sealants are introduced through the valve. The instructions for using the sealant are always included or written on the bottle. Inserts or harnesses are placed on the puncture outside of the tire.

  • installing the patch. This method, called “cold vulcanization”, is more expensive, but allows you to forget about the puncture by gluing a patch on the inside of the tire and then balancing;
  • installation of the fungus. This is a combined method for wider punctures. Repair method with tire disassembly without hot vulcanization. This method is used only if there is a puncture on the treadmill. With this method of repairing tubeless tires, you can seal small punctures from the inside with a patch. Damage (necessarily processed) up to 6 millimeters in diameter is repaired as follows: 1) fungus, the axis of the hole should be perpendicular to the surface of the treadmill; 2) with a leg (if the angle of inclination is more than 25 degrees), you must first seal the hole channel and glue a universal patch from the inside.
    When repairing tubular tires, it is necessary: to restore, with the help of a patch, the tightness of the tubing; remove the hole in the tire.

“Fungus” is a tourniquet, on the inner end of which a patch for reinforcement is installed, which acts as a “hat”;

  • installing a camera in a tubeless tire. A temporary repair method when the wheel no longer makes sense to repair. The camera wheel is best used as a spare;
  • hot vulcanization. This is an expensive repair that involves installing a special rubber patch and soldering it with a hot press. Due to the high cost, the method is used to restore extremely expensive tires.

Disk repair

There are the following types of discs:

  • Alloy wheels;
  • Forged and steel (stamped) wheels;
  • Discs without center hole (French discs);

We offer the following types of repairs:

  • Repair of alloy wheels, as well as exclusive car wheels;
  • Local restoration of the appearance of a car rim (seizures, scratches, chips, damage to the bardyur);
  • Recovery (restoration) of missing disk fragments;
  • Recovery of disk geometry;
  • Repair of chips and cracks using argon-arc welding;
  • Repair of the figure eight on the disk;
  • Straightening discs;
  • Elimination of axial battle.

Correct sequence restoration of a cast or forged wheel begins with a thorough washing to identify all its microcracks and scratches. Further, the wheel is checked with special micrometers for the presence of axial or radial runout, so that this is taken into account at further stages of repair. And only after reaching full balancing, you can proceed to the following points of the algorithm.

According to the recommendations of the rim manufacturers themselves, the best way to recover discs is the cold method. This technology does not produce local heating and does not spoil the structure by rolling rollers. The cold recovery method involves the use of special equipment to pull the disc back to its original factory shape.

The next stage of restoration is to repair cracks and scratches. But there is one very important limitation – cracks at the base of the spokes of alloy wheels and near the mounting holes cannot be repaired, and a disc that has received such damage cannot be safely operated further.
