Tire mounting<\/strong><\/p>\n

Tires may only be mounted by specially trained personnel using appropriate tools and procedures. RGC recommends finding a local tire changing facility that is familiar with motorsport or at least “run flat” tires. Tires should be stored in a warm and dry room at a temperature of at least 20 degrees Celsius for 24 hours before mounting. RGC recommends balancing the wheels. <\/p>\n<\/div><\/div><\/div>

Table with sizes <\/strong><\/p>\n

It is a common mistake to use rims with the wrong width in relation to the tire width. RGC strongly recommends that you consult the values in the table below when selecting tires for your vehicle. For track use, RGC recommends the upper width. <\/p>\n<\/div><\/div><\/div>

    Tire pressure recommendation<\/h4>\n<\/div><\/div><\/div>

    Tire pressure is an incredibly important factor that affects both safety and tire performance. To ensure safety and trouble-free driving, RGC recommends taking frequent measurements with a professional tire pressure gauge and adjusting it when necessary to correct the values. Exceeding the lower limit of the recommended pressure can cause excessive and improper tire wear, which can lead to an accident. These are general recommendations, not precise instructions that must be followed. <\/p>\n<\/div><\/div><\/div>

    \n\n\n\n\n\n\n\n

    The pressure values recommended by the manufacturer must be adhered to first and foremost. Front-wheel drive vehicles are the most demanding in terms of tires. The front axle is responsible for turning, accelerating and braking, which together put much more stress on the front tires compared to rear or all-wheel drive vehicles. Therefore, higher pressure may be required to ensure proper operating conditions for the tires. <\/p>\n

    For vehicles with aero packages, 0.2 bar higher cold pressures should be used. Vehicles equipped with aero packages generate more downforce, which leads to a higher load on the tires. A slightly higher starting pressure should therefore be used. <\/p>\n

    DISCLAIMER!<\/strong> The pressure values in the adjacent table are calculated for dry conditions and asphalt. For wet tires, lower pressures are permitted in wet conditions, but they must not fall below 1.7 bar. Due to the different rain conditions, it is impossible to set the same tire pressure guidelines for wet tires as for dry tires. <\/p>\n<\/div>

    Running-in procedure for tires<\/strong><\/h4>\n

    The first few kilometers covered with a new set of tires are crucial for durability and performance. Before each competition, it is recommended to ride 10 km at a pressure 0.3 bar higher than the cold pressure recommended in the tire pressure recommendation table<\/strong>. During tire break-in, avoid locking the tires under braking and excessive acceleration that could lead to wheel spin. If it is not possible to break in the tires earlier, RGC advises that the first session be run at 70% of race speed and at a cold pressure 0.3 bar higher than that recommended in the tire pressure recommendation table<\/strong>. The aim of running in is to gently reach the working temperature of the compound and then cool the tire, which ensures better durability and performance. RGC recommends breaking in the tires at least one day before the planned competition. <\/p>\n<\/div>

    Tire rotation<\/h4>\n

    To maximize tire life, RGC recommends frequent tire changes between the axles and sides of a vehicle.<\/p>\n

    Driving style<\/h4>\n

    Driving style has a big impact on the durability of a tire. More aggressive drivers tend to wear and heat up the tires more than calmer drivers, so they should consider choosing harder compounds. It is also very common for drivers to tend to turn the steering in too far and understeer, which has a negative impact on tire durability and performance. RGC tires perform best at low slip angles, so a smoother and quieter driving style will give the competitor better lap times and less tire wear. <\/p>\n

    Tire storage<\/h4>\n

    RGC products are best stored at room temperature. Tires should not be stored at temperatures below 5 \u00b0C. RGC advises against leaving the car on the tires for long periods of time, as this can lead to deformation of the tire or “cold cracking” can occur with hard compounds. <\/p>\n

    Limited warranty<\/h4>\n

    RGC Motorsport tires are designed for special competitions and there is no warranty except for obvious manufacturing defects.<\/p>\n

    Tire modification<\/h4>\n

    RGC does not prohibit any modifications to the tire (e.g. cutting for rain), but accepts no responsibility for this.<\/p>\n

    Application in everyday life<\/h4>\n

    RGC tires are not as versatile as normal road tires due to the use of motorsport compounds. Therefore, hard compounds should not be used in temperatures that are too low and soft compounds should not be used in conditions that are too warm. Failure to observe the recommendations can lead to accidents or even death. <\/p>\n
