* - Load index and speed symbol are given on tire side.
** In tires 580/70R42 Bel-126М 158D (158А8), it is allowed to set inner pressure of
100 kPa only in outer tires (at operation with twin tires).
Rates of loads are provided for tires with indicated load index and speed symbol.
Pressure shall be set in "cold" tires.
Performing operations which require large pulling force on the hook, set the pres-
sure as for the speed of 30 km/h.
When performing transport operations on roads with hard surface, increase pres-
sure by 30 kPa, but no more than maximum permissible pressure according to table 3.2.2.
If transport operations increase 60%, the warranty lifetime of the tire within the limits
of warranty storage time decrease by 30%.
Tractor operation with twinned tires is allowed only at the speed of 20 km/h.
Maximum permissible loads are given for single tires. Total permissible load G
tyres pair at twinning makes 1.7G, where G is permissible load on single tire according to
table 3.2.2.
When twinning tires, make sure the pressure in outer tires is 1,2 – 1,25 times lower
than the pressure in inner tires.
Permissible maximum pressure deviations in tires are (±10 kPa) according to ma-
nometer indication.
Rear wheel tires 650/65R42 and front wheel tires 480/65R24 is an alternative con-
figuration.
