Common use of Load and pressure Clause in Contracts

Load and pressure. 3.1.4.1. For C1 tyres, the vehicle load shall be such that the resulting loads on the tyres are between 60 per cent and 90 per cent of the load corresponding to the tyre load index. The cold inflation pressure shall be 240 kPa. For C2 tyres, the vehicle load shall be such that the resulting loads on the tyres are between 60 per cent and 100 per cent of the load corresponding to the tyre load index. The static tyre load on the same axle should not differ by more than 10 per cent. The inflation pressure is calculated to run at constant deflection: For a vertical load higher or equal to 75 per cent of the load capacity of the tyre, a constant deflection is applied, hence the test inflation pressure "Pt" shall be calculated as follows: Qr is the maximum load associated to the load capacity index of the tyre written on the sidewall Pr is the reference pressure corresponding to the maximum load capacity Qr Qt is the static test load of the tyre For a vertical load lower than 75 per cent of the load capacity of the tyre, a constant inflation pressure is applied, hence the test inflation pressure Pt shall be calculated as follows: Pr is the reference pressure corresponding to the maximum load capacity Qr Check the tyre pressure just prior to testing at ambient temperature.
