Tyre Care & Safety Tips

• Always check that your tyres are inflated to the correct tyre pressures. We recommend they are checked at least once per week. You must do this when the tyres are cold.
• Make sure you regularly check for and remove foreign objects such as stones from in between the tread blocks. If you allow them to become embedded they may work themselves into the casing and cause tyre deflation.
• Check your tyres regularly for uneven wear. Uneven wear may indicate a problem with the steering geometry of the vehicle and an adjustment may be needed to the vehicle ‘toe-setting’ or other alignment angles. In some cases uneven wear may indicate a more serious problem with worn or damaged components in the suspension/ steering assembly.
• Symptoms of uneven wear may also be accompanied by anomalies such as the vehicle pulling to one side.
• Ensure that all oil and similar petroleum products are not left in contact with your tyres for a long period of time. These products can cause separation within a tyre if they are left in contact with the surface of the tyre.
• Every time a tyre is replaced or repaired make sure a new valve is fitted to that tyre, as sometimes it can be damaged during the removal process. Good tyre dealers should always do this unprompted, but always check beforehand.
• Having your wheel and tyre assembly checked for balance regularly is important, as a unbalanced wheel will cause uneven tread wear as well as vibrations through the steering.
• Check tyre side-walls for bulges or cuts and anything else out of the ordinary, as this is especially important when using your vehicle off-road frequently. The potential for this sort of damage can be reduced if you buy tyres with reinforced sidewalls, such as the BF Goodrich All-Terrain TAKO and TAKO2.

Always check that your tyres are inflated to the correct tyre pressures.

• Always make sure your tyre is above the legal limit of 1.6mm. We recommend tyres are changed before this point as braking and grip on a badly worn (however still legal) tyre can be up to 50% less efficient than a new tyre. Also, worn tyres will aquaplane across water more readily than a new tyre, which displaces water much more efficiently.
• Tyres of different sizes should never be mixed on the same axle unless recommended by the vehicle manufacturer (ie. Space Saver spare-wheel). Having different size tyres on different axles can cause handling and mechanical problems unless recommended by the vehicle manufacturer.
• ALWAYS try to change all 4 tyres at a time or at least ensure there is no more than a couple of mm difference between the front and rear tyres. If less than 4 tyres are to be fitted ensure you fit at least a pair, with the 2 new ones fitted to the REAR and the next best two tyres fitted on the front.*
• The mixing of radial and X-ply tyres on a vehicle is not recommended. However if you do mix you must fit X-ply to the front axle and radial to the rear axle (legal requirement).
• Always ensure that tyres fitted to your vehicle have the correct specification load and speed rating. Most modern 4X4 tyres have a reinforced load carrying, however car tyres of the same size have a reduced carrying capacity. If you are not sure of the correct load/speed rating that you require please call your local 4Site 4X4 office.
• It is highly recommended that when fitting a tube into a tubeless tyre (where a tube is made) that all foreign objects including manufactures builders tags are removed from the inside of the cover and also French chalk is used. It is also advisable that a quality tube is used as well.

Always make sure your tyres are above the legal limit of 1.6mm.
