Dumper Tyre Tips
The typical dumper tyres
The typical tyre for these conditions is an open centre lug pattern. These type of STARCO tyres fall under the ETRTO regulations within the category of: Agricultural Equipment – Implement Tyres.
Because Dumpers operate on sites where distances are limited and operating speeds are less than the tyres capability of 40 km/h we also have the opportunity to adjust loads according to these lower operating speeds.
The STARCO tyres for site dumpers are the STARCO AS Dumper and STARCO MP Dumper ranges. Last year STARCO mounted and supplied 35,000 of dumper tyres to site dumper manufacturers in the UK. STARCO is the market leader in dumper tyres in the UK and has more than 55 years’ of experience in developing and manufacturing wheels and tyres.
Reasons for tyre damage
Apart from accidental damages, poor maintenance is one of the main reasons for tyre failures.
Tubeless tyres and valves are not completely airtight. They lose air naturally, as the air molecules pass slowly through the body of the tyre and valve, gradually reducing the air pressure.
When running underinflated, the sidewall of the tyre is over flexing causing undue strain on the casing of the tyre. Also, the over flexing causes the bead to rock over the rim flange/horn wearing the bead, and also allowing foreign matter to enter into the interface between tyre and wheel. A pressure maintenance schedule is vital to achieve a full tyre service life.
Due to the type of work that dumpers do – Empty/Full/Empty cycles – a dumper that is empty will appear to be okay, because the tyres will generally have more than enough pressure to support the empty weight of the vehicle. However, as soon as the skip is filled the tyre will be underinflated for the load.
This underinflated running can have many consequences: The sidewall of the tyre is over flexing causing undue strain on the casing of the tyre. Also, the over flexing causes the bead to rock over the rim flange/horn wearing the bead, and also allowing foreign matter to enter into the interface between tyre and wheel. A pressure maintenance schedule is vital to achieve a full tyre service life.
5 tips to prolong the life of your dumper tyres
Follow these 5 tips and you will get the most of your dumper tyres.
Tip 1: Always check tyre pressures once a week.
Tip 2: Always check the tyre pressure before use when the tyre is cold (un-run).
Tip 3: Never reduce the pressure of a warm tyre.
Tip 4: Always fit sealing valve caps after inflation and replace if damaged.
Tip 5: Always inflate the tyres to the pressures recommended by the vehicle manufacturer.
