(1)For intermediate maximum speeds, linear interpolations of
the tire load capacity is permitted.
(2) For speed capabilities over 300 km/h, the load capacities
& the relevant inflation pressures will be agreed between vehicle
& tire manufacturers (or their national associations) taking in to
consideration the vehicle characteristics & the type of service.
The load capacity quoted in the Standard Manual is the maximum load
"per tire" permitted for speed "up to & including 210 km/h".
For speed in excess of 210 km/h, the maximum load per tire shall not
exceed the following percentages of the load capacity quoted in the
tables, depending on the type of tire & on the speed capability of
the vehicle.
For ZR Tyres, the actual speed capabilities, load capacities & the
relevant inflation pressures will be agreed between vehicle & tire
manufacturers (or their national associations) taking into
consideration the vehicle characteristics & type of service.
In the absence of such agreement, it is recommended that for speed
capabilities between 240 & 270 km/h, the load capacities & the
relevant inflation pressures of ZR tires be the same as for tires "W"
