Which repair is best for my agricultural tyre?

How to tell a poor repair, and which tyre specialist to use

If your agricultural tyre is damaged, you’ll have two types of repair that you could make: temporary and permanent. In this article, you’ll learn how to spot that your tyre repair has been bodged.

When might you need a temporary agricultural tyre repair?

Temporary repairs should only be made to get your vehicle or machinery back to the yard. Patches should not be used for more than 24 hours, and may not be possible if the damage is too large. For this type of damage, you should have the tyre repaired permanently.

You might be tempted to make a temporary repair, especially if time is tight (when isn’t it?), but a professional repair will prolong the life of your tyre and save money and time in the long run.

Do you need a permanent agricultural tyre repair?

Permanent repairs are more expensive than temporary fixes. This cost saving, though, is as temporary as the temporary. A temporary repair could be a false economy.

When considering which type of repair is best for your agricultural tyre, you should consider what work it will be doing. The heavier the load and tougher the ground, the harder your tyre will need to work. A temporary fix could fail fast.

It’s very tempting to make a temporary fix on tyres that are used on handling equipment. A temporary repair is quick and cheap, and the equipment is only used in a confined area and only now and again. But what if the tyre fails? Suddenly you have an expensive repair, and, most importantly, you’re putting the operator at risk.

What type of permanent repair is best?

When a tyre is repaired permanently, the repair can be made by hot or cold vulcanising. You should know the difference before deciding which you need.

Vulcanisation is the tyre equivalent of welding. Using sulphur, the tyre and patch are bonded together, making a permanent seal.

Hot vulcanising is faster than cold, and best for larger damage. However, it requires specialist equipment, and your tyre will need to be sent away for repair.

For smaller repairs in the centre of the tread, cold vulcanising may be best. The repair will take a day to make, with the tyre and patch bonded at 18 degrees Celsius. Usually, this process can be made at a tyre shop, though it may be necessary to send the tyre away for repair, depending on the extent of the damage.

If you decide on the wrong type of repair, even if it is done perfectly the result could be as bad as the right repair done poorly. Always take advice from a tyre specialist before making your decision.

How can you tell a bodged tyre repair from a good one?

There are several giveaway signs that a temporary repair has been bodged. These include:

  • Rough edges to the repair
  • The patch is pulling away
  • Bulges are visible
  • Multiple repair patches

If you spot any of these conditions, you should stop using the tyre immediately and take it to a tyre specialist for a full examination. Multiple repair patches are a sign that the wrong type of repair has been made, and made badly.

Poor permanent repairs are harder to detect because most of the work is internal. A spectrometer is needed to inspect the tyre. It is like an X-ray for tyres and examines behind what might look like a perfect patch on the outside.

How can I tell which repairer to afford?

If a tyre repairer is offering a bargain basement price on a tyre repair, the chances are that you’ll get a bargain basement repair. Agricultural tyres and repairs are the same as most commodities – you get what you pay for. If your agricultural tyre is damaged, have it checked by a reputable tyre specialist.
