Attention points for using tyre

Tyre should be fixed on corresponding rims of the same model, requirements and size.

The same axel should be assembled with tyre of the same specifications, brands, size, ply rating, atmospheric pressure and patterns.

All tire of vehicles should be replaced when replacing with new ones. Otherwise new tire should be fixed on the outer side of the front or rear axle.

When simultaneously fitting the two tyre of the rear axle, the rotation marks of tire should point to the forward drive direction.

Tyre should be inflated to standard internal pressure, but on roads of 4% higher camber, coaches can have 0.2-0.3kgf/cm lower than standard internal pressure in front and rear inside tire.

The lode of tire is subject to the max load stipulated for singal tyre. No overload is allowed and the load should be well distributed.

When changing position, all tyre should be changed simultaneously. Be sure not to change the original drive direction of tire.

When binding tyre chians, two sides should be bound. After passing through slippery road, the chains should be remove. Too tihgt or too loose chians may damage the tyre side and the surface of the tyre.

Regularly check the tyre. When rip or hole are found, they should be immediately mended in case the damage will be expanded.

The external tyre should be fixed on standard nms. And keep the rim edge in good condition. Regularly rust and add antirust oil.

Chemical Drawing

Prophylactic properties of a new chemical drug, arbidol, against acute respiratory diseases (ARD) were studied. Arbidol given daily in a dose of 0.2 g for 19 days reduced the morbidity rate 2.3-fold in adults during an outbreak of ARD. Geometric mean titres of antibodies to respiratory viruses among healthy persons did not change after treatment with arbidol indicating the lack of immunosuppressive properties in the drug. The prophylactic effect of arbidol may be due to both specific effect of the drug on influenza and parainfluenza viruses, and its interferon-inducing and immunity-stimulating properties
