Blog September – harvest and planting

Depending on the weather July, August, September and October are our busiest time of year for tyre repairs, replacements, call outs  for agricultural vehicles. Harvesting followed by drilling and planting brings in big demand for our services on site and in some very interesting locations!

The call outs includes tyre repairs and replacements for everything from combines, to tractors. We have a wide range and large stocks of tyres for agricultural vehicles and tractors.

Some of the agricultural vehicles we supply tyres for:

  • Tractors
  • Forestry
  • Combines
  • Trailers
  • Liquid manure spreaders
  • Sprayers
  • Cultivators
  • Row Croppers
  • Front wheel drive vehicles

Tyres for agricultural vehicles have to fulfil a whole range of terrains and working conditions. For some farmers, the amount of time spent on hard surfaces can be as much as 50% of the working time of their vehicles. Farmers and animal breeders e.g. spend an increasing amount of time running over tarmac surfaces, including farmyards, roads between silos and storage sites, plus journeys to access fields which might be field tracks or tarmac tracks.

Add in greasy mud and snow or frosty ground, farmers and the agricultural industry need tyres that offer longevity, comfort, stability and resistance to aggression. With over 30 years experience in the earthmover tyre industry you can be certain you will receive the right advice on tyres for your needs and therefore be able to optimize the performance of your agricultural machines. Your efficiency and safety are our main concerns.

Fitting and removing tyres

An agricultural tyre must be dismounted and mounted by a trained, qualified professional, using the appropriate tools and procedures. Make sure that one person at least one person is present during all operations.

Use a compressed air circuit equipped with a correctly adjusted pressure gauge.Not following these instructions and procedures may cause incorrect mounting of the agricultural tyre onto the rim and could also cause the tyre to burst, leading to a risk of serious injury or fatality.

1- Removing the tractor tyre from the rim

Check out the safety rules and precautions necessary to mount or remove ag, tractor and trailer tyres safelyDo not try to dismount the tyre while it is still inflated. This is what we do

Required : remove the valve core.

Ensure that the tyre is fully deflated before starting to remove itNever use a tool liable to damage the agricultural tyre sidewalls or beads Unseat the beads starting from the removal notches when present on the tyreLubricate the rim flange and tyre beads to facilitate removal and avoid damage to the seats, especially when a puncture is involvedIf the rim shows apparent signs of damage, deflation is required prior to removal of the wheel/tyre assembly.

2- Preparing for fitting

Check out the safety rules and precautions necessary to mount or remove ag, tractor and trailer tyres safelyBefore mounting the tyre, make sure the rim, tyre and inner tube are compatible. This is what we do hope you use our services but if not at least do thi.

  • the tyre is suitable for the machine
  • the diameter at the “seat” of the rim corresponds to the diameter at the “seat” of the farm tyre to be fitted (example: a 18.4 R 30 tyre, Rim: DW16L x 30)
  • this tyre may be fitted onto this rim.

Before mounting an ag tyre onto a rim that has already been used:

The tractor rim must be clean and show no signs of damage. If the rim is not clean, use a metal brush to clean it.  Never mount a tyre to a cracked, deformed rim showing signs of breaking or traces of welded repairs…

If the tractor tyre has been used, closely examine it, inside and out, to identify any damage that may need to be repaired before mounting. If it shows signs of deterioration or degradation considered non-reparable by a specialist, replace the tyre.

When fitting with an inner tube, always use a new inner tube suitable for the size of the tyre (inner tubes are marked with the sizes of compatible tyres). Do not fit an inner tube onto a damaged or repaired rim or one with irregularities. To fit a Tubeless tyre without an inner tube onto a Tubeless rim, ensure a new Tubeless valve is inserted each time.

Use tools that are in good condition – ones that are clean, not sharp and suitable for the tyres and rims (bead-breakers, levers, machines, etc.).

For wide or large volume tyres it is preferable to use an automated bead pusher or a bead breaker (appropriate mechanical assistance) to fit the second bead.

Before fitting the tractor tyre, lubricate the rim seats and tyre beads. Apply a fine coating of lubricant on the parts indicated in the drawing opposite. On the outside of the beads the lubricant must be applied up to 2 inches higher than the edge of the rim. The inside of the bead should also be lubed to prevent damage.

Only use products suitable for this use that will not damage the tyre: hydrocarbon-based products, silicone and antifreeze are not to be used.

3- Vertical fitting of the tyre on the rim

Check out the safety rules and precautions necessary to mount or remove ag, tractor and trailer tyres safely Position the valve or valve hole at the bottom of the tractor wheel.Position the bead-breaker “window” away from the location of the valve to avoid damaging the bead on the latter.Place the tyre into the rim so that the first tyre bead is positioned on the edge of the rim.  If applicable, adhere to the rotation direction indicated on the tyre with an arrow.

  • Using a suitable lever and with successive touches around every 4-6 inches:
  • Bring the first bead over the edge of the rim and push it into the deepest rim well.
  • Once the first bead has been inserted:
  • fix the valve, tightening the nut lightly
  • if an inner tube is being fitted, position the inner tube slightly inflated inside the tyre

4- Inflating and seating of the beads

Safety

  • The safety rules to be applied are:
  • Retention system to hold the agricultural tyre assembly in place (safety cage)
  • A pair of protective goggles
  • Safety shoes
  • Safety ear muffs
  • Check out the safety rules and precautions necessary to mount or remove ag, tractor and trailer tyres safely
  • If there is no safety cage or bar, the mechanic should stand as far as possible from the tyre and rim as possible.

Note: never stand in the paths indicated to avoid any risk of physical injury in the event of an accident or incident.To maximise safety, use an inflation gun with a calibrated pressure gauge, connected to the valve by an air extension tube at least 10 feet long, equipped with a clip system on the valve side and in perfect working order –never block the handle.

Precautions

Above all, check:

  • that the beads are correctly in position, centred in relation to the edges of the rim. Inflate up to 35 psi without exceeding this pressure.
  • If the beads are not correctly positioned:
  • deflate, lubricate again and inflate to a pressure of 35 psi
  • repeat these operations until the beads are correctly in place
  • Then :
  • replace the valve core
  • tighten the valve nut by hand

inflate to the operating  pressure determined, according to the load scales indicated in the manufacturer’s documentation or to the storage pressure

screw on the valve cap whenever a tyre has been inflated or the pressure checked because this part alone keeps the valve clean and airtight

Note: All radial tyres used at low pressure must be mounted onto good quality rims.

5- Before tyres go in to service

When machines are being transported (by road, rail or ship), we recommend agricultural tyres be inflated to 26 psi to avoid any possible damage from certain anchorage systems.

When the machine is put into service, the pressure must be determined and adjusted according to the load supported by the tyres and actual conditions of use.
