5. Operating Instructions
7. Tyre handling General This is a general instruction for the standard tyres in the table under item 7.2. Contact tyre supplier or your local Moxy Dealer for exact specifications. Off-road tyres produce more heat during operation than tyres for ordinary cars. Therefore, the tyres must be used correctly to obtain long lifetime and safe operation. Please note that the following can cause overheating of tyres: • Too low tyre pressure • Overloading • Driving long distances non-stop • Travelling at high speed
CAUTION Extremely low temperature (below -40°C) requires special operation!
7.1. Difference in tyre diameter If it is necessary to change a wheel as a result of puncture or in emergencies, Moxy Engineering AS allows up to 3% difference in the tyre diameter on the same side of the tandem. But the most ideal situation in all cases is to have the same tyre diameter on the same side of the tandem. This is strongly recommended. 7.2. Correct tyre pressures Tyre pressures mainly depend on operation speed and load. Road configuration, flotation/traction requirements, risk of cutting, hacking, shock damage and ambient temperatures, are also factors to consider. Both too high and too low tyre pressure may result in damage and shortened lifetime of the tyres.Tyre pressure checks and corrections must be carried out on cold tyres. Basic pressure for cold tyres (based on max. load and max. speed):
