FAQ

Here there are answers to the most frequent questions concerning tyres. Our answers are intended to help you understand what to do to prolong the tyre life. To find the answer to your question, choose the cathegory from the list below.

Inflation pressure loss

Tyres often indicate to their owners that something goes wrong and that using an expert analysis deficiencies are to be detected and eliminated. Learn to “read” the warning signs to prolong the tyre life and to prevent problems arising from inadequate use. Below you can find some facts concerning tyre maintenance.

An adequate inflation pressure is a key to safe drive and long tyre life. Always use the inflation pressure recommended by the manufacturer of your vehicle. You can find the recommendation in the technical manual of your vehicle, however it could be also printed:

  • on the inner edge of the driver’s door,
  • on the door jamb,
  • on the label located on the inner side of fuel tank cover.

Pressure checks should be made when the tyres are cold,after driving:

  • not more than 2 km far
  • not less than one or two hours after a drive.

Use only high quality pressure gauges. Do not forget to check your spare tyre. Your tyre dealer can give you an answer to any question concerning the inflation pressure of your tyres.

If a tyre has been run at low or zero pressure it must be dismounted from the wheel for a thorough inspection to determine whether it has been damaged or not. Tyres that have been run flat even a short distance are usually damaged so as to render impossible any repair. The major part of defects, nail holes and notches up to 6 mm in depth – within the tread area – can be sufficiently repaired by professionals using industry approved methods.

Never repair tyres that have tread damage more than 6 mm deep, or a damaged sidewall. Do not repair tyres having the remaining tread depth less than 1.6 mm.

However, the best practice is to be always sure that your spare tyre is ready to be used. Regularly check its inflation pressure and be sure of its good condition.

For the variety of possible causes for a pressure loss the right answer can be given only by an authorised tyre dealer. Some common causes of inflation pressure losses:

  • Damage due to poor road conditions (holes, notches, carcass, cord or sidewall damages).
  • Valve body or valve core lakages (damaged or worn body or ramshackle or damaged core).
  • Leaking tyre bead base (rusty rim reducing tightness between the rim flange and tyre bead, tyre bead base damage due to mounting/dismounting damage, a foreign body between the rim and tyre bead base, rim deformation, …)

Balancing – alignment

Never attempt to mount a tyre by yourself.

Tyre mounting is a procedure requiring professionals with adequate equipment and sufficient experience.

Doing it by yourself you run the risk of injuring yourself or damaging the tyre or rim.

An adequate inflation pressure is a key to safe drive and long tyre life. Always use the inflation pressure recommended by the manufacturer of your vehicle. You can find the recommendation in the technical manual of your vehicle, however it could be also printed on:

  • the inner edge of the driver’s door,
  • on the door jamb,
  • on the label located on the inner side of fuel tank cover.

After driving:

  • not more than 2 km far
  • not less than one or two hours after a drive.

Correct and regular rotation of tyres leads to more even wear of the vehicle’s tyres. Tyres should be rotated considering the “cross X” model meaning that the rear axle tyres are moved to the front drive axle so as to position the rear rignt wheel tyre onto the front left wheel, and the rear left wheel tyre onto the front right wheel.

The two remaining tyres from the front drive axle are moved to the rear axle, maintaining them at the same side of the vehicle (left to the left wheel and right to the right one). This rotation method leads to more even tread wear of all four tyres.

The only exception of this method are directional tread pattern tyres as for exemple our Intensa. Directional tyres would remain on the same side of the vehicle and be rotated straight forward and straight back.

For 4-wheel drive vehicles it is recommended to exchange the rear left and the front right tyres, and the rear right and the front left.

Follow rotation recommendations indicated in the technical manual of your vehicle. If the period after which the tyres are to be rotated is not defined, do it every 5000 to 7000 kilometers. The first tyre rotation is of cruscial importance. When rotated, tyre inflation pressure should be according to the vehicle manufacturer’s recommendations.

However, uneven wear can also be a consequence of an optical misalignment of the vehicle or of mechanical problems. Sava dealers can provide you an expert diagnosis and repair.

A vehicle is properly aligned when all suspension and steering components are sound and when the tyre and wheel assemblies are running straight and true. Correct optical alignement is important to assure even tread wear and precise vehicle steering. Uneven front or rear tyre wear or changes in vehicle steering response (the vehicle tends to drift to one side) can indicate a misalignment.

The alignment to be done (either optical alignment of the front or of all the four wheels) is dependant on the signs your vehicle shows. Optical alignment cost is moderate and is compensated by enhanced tyre mileage, grip, handling and comfort.

Vibrations indicate that your vehicle has problems and requires special attention. To determine possible cause and eliminate vibrations, you must have your tyres, suspension and steering system inspected. Several tyre dealers offer expert diagnosis and repair services

Properly balanced tyres provide for comfort riding and a long tyre life. Unbalanced tyres can cause vibrations resulting in:

  • premature tyre wear,
  • unnecessary wear to your vehicle’s suspension,
  • driver fatigue.

Your tyres should be balanced when they are first mounted on your vehicle and when they are remounted after a repair. Tyres require rebalancing at any sign of vibration or vehicle shaking.

Vibrations can also be a consequence of an optical misalignment of the vehicle or of mechanical problems. Several tyre dealers can provide you an expert diagnosis and repair service.

Care for tyres

Driving new tyres is quite different from driving eliminated old worn tyres. Drive carefully until you get familiarized with the behavior of your new tyres. Pay special attention when:

  • braking,
  • accelerating,
  • cornering,
  • driving in wet,

because in such situations the differences between the old and the new tyres are most evident.

Tyres have treadwear indicators (TWI) located at the bottoms of the tread grooves in six locations around the tyre. When a tyre tread is worn to the point where any of them become visibly flush with the adjacent tread ribs, it is time to replace the tyre.

  • Due to chemical and physical processes tyres are subject to ageing even if they are not in use.
  • A spare tyre maintained in your car boot for more than six years may be used only in case of emergency.
  • Never use already used tyres if you don't know their history.
  • Tyres should always be stored in a dry, cool and dark place.
  • Protect them from petrol, oil and grease.
  • Never clean tyres using high pressure water jets.

If a tyre has been run at low or zero pressure it must be demounted and thoroughly checked to determine whether it has been damaged or not. Tyres that have been run flat even a short distance are usually damaged so as to render impossible any repair. The major part of defects, nail holes and notches up to 6 mm in depth – within the tread area – can be sufficiently repaired by professionals using industry approved methods.

However, the best practice is to be always sure that your spare tyre is ready to be used. Regularly check its inflation pressure and be sure of its good condition.

A replacement tyre to be fitted must be of the same size rating or must match the size recommended or approved by the vehicle’s manufacturer.

Tyres of different size, construction or wear rate influence the stability and handling of the vehicle. All tyres are required to be of the same size, construction (radial, cross-ply) and speed rating. For more information contact your tyre dealer.

Driving

Of caurse, they can. Here are a few basic tips to extend the life of your tyres:

  • Do not drive at too hogh speed: excessive deformation and heat generated at high speed driving increase wear rate of tyres and reduce their service life.
  • Avoid fast cornering, quick starts and immediate stopping.
  • Do not drive over kerbs, edging stones, potholes or similar obstacles.
  • If an obstacle is unavoidable, drive over at right angle as slowly as possible.
  • Respect maximal permitted load, considering the weight transmitted to the vehicle hook by the trailer.

Sava Tires doesn’t give any written statement regarding kilometers of service a tyre can provide. Due to different technologies, particularities of manufacture, vehicle applications, geographical conditions, driving habits and maintenance practice; accurate predicting of specific tyre mileage is not possible.

However, if you are concerned with the mileage of your tyres, contact your nearest tyre dealer to get a professional advice.

  • Summer tyre tread gets hard at low temperatures reducing grip and increasing breaking distance.
  • Winter tyre tread is softer to assure excellent grip, especially at low temperatures; however, on hot summer asphalt this leads to excessive wear.
  • It is recommended to replace summer tyres when the tread depth is under 3 mm. Following Slovene legislation, tyres for M1 and N1 cathegory vehicles and their trailers should have a minimum tread depth of 1.6 mm, motorcycle tyres not less than 1 mm and other vehicles at least 2 mm, what however is not enough for a safe drive.
  • Winter tyres have an extra marking M+S. Winter tyres assure the maximum safety if fitted on all four wheels.
  • In our climatic conditions it is recommended to switch to winter tyres in November or when temperatures fall under 7°C at the latest.
  • The safest and the most economical practice is to change from summer to winter tyres at the rotation of summer and winter period.

Mounting

  • When purchasing new tyres pay special attention to their rated size and the maximum allowed speed and weight of your vehicle.
  • Tyre size is indicated by the section width and cross section, rim width and load and speed indices.
  • The speed rating of you tyres should be equal or greater of the speed rating of your vehicle. If the speed rating of you vehicle is 183 km/h, it requires tyres allowing at least the speed of 190 km/h.
  • Load capacity of your tyres should correspond to the maximal allowed weight of your vehicle. It is indicated by the load index printed on the tyre sidewall next to the speed symbol.
  • Fit only tyres recommended by the vehicle’s manufacturer.

If a tyre has been run at low or zero pressure it must be demounted and thoroughly checked to determine whether it has been damaged or not. Tyres that have been run flat even a short distance are usually damaged so as to render impossible any repair.
