Can motorcycle tyres be repaired?
In some specific cases, it is possible to repair a punctured tyre on a motorcycle. But it is unlikely that you will be able to make the correct diagnosis yourself.
Why? Firstly, because you need to be able to access the inside of the tyre. Secondly, because it takes the eye of a professional to assess its condition and determine the correct diagnosis.
Depending on the condition of your tyre, he will either repair it or recommend replacing it. It is therefore imperative that you take your tyre to a specialist as soon as possible so that he can draw conclusions about your tyre.
Of course, it is difficult to show your tyre to a professional if you are far from the next garage and your tyre is flat! In this case, it comes down to one of two things:
You have a motorcycle tyre repair kit: if you manage to identify the puncture, use your kit to temporarily repair* your tyre so that you can get to the nearest garage.
If you don't have a motorcycle repair kit: you need to have your motorcycle towed to the nearest garage. Usually, a call to your insurance company is all that is needed to get a breakdown mechanic involved.
If the tyre bead is damaged (if it comes out of the rim), we advise against a temporary repair with your kit. Have your motorcycle towed away by a breakdown service.
The motorcycle tyre repair kit
In a motorcycle tyre repair kit, there are usually wicks for temporary repair of a motorcycle tyre. To patch a punctured tyre, the wick is inserted with a tool from the outside, so that the hole is sealed. The spray can, usually included in the kit, is then screwed onto the valve and the tyre can be re-inflated.
It is important to know that this type of repair can only be temporary. Firstly, because a wick inserted into the tyre in this way does not guarantee a complete seal. Secondly, because driving after a puncture without having the inside of the tyre checked by a professional is a major safety risk.
The motorcycle tyre repair kit and its contents are only a temporary solution to enable you to drive to the nearest professional so that he can diagnose your tyre.
Perhaps you are wondering how a tyre is repaired in a sustainable way?
This is precisely what we will explain in the following paragraph.
How is a motorcycle tyre repaired?
Mushroom tyre repair (PRP)
The most effective repair, when possible, is the "mushroom" repair, also called PRP.
The name of this accessory comes from its mushroom shape: a stem fits into the hole to prevent air circulation and a flat part at the top seals the hole from the inside.
This is the most effective repair as it prevents air from escaping the tyre, but also water, dirt and any other external elements from entering the hole. It requires access to the inside of the tyre (unlike the wick, which is inserted from the outside) and must therefore be carried out by a professional. The professional follows specific steps to make the repair both effective and durable.
Repairable areas of the tyre
The repairability of a motorcycle tyre depends on the puncture area.
A tyre is only repairable if the hole is in the T-zone shown in the diagram, i.e. about three quarters of the tread.
This area excludes the edge of the tread and the sidewall of the tyre where a repair would not hold.
The limits of tyre repair
Other criteria for determining whether a tyre is repairable are the speed rating, the diameter of the puncture and the number of repairs.
Speed rating | Maximum hole diameter | Maximum number of repairs |
< VR | 6 mm | 2 |
ZR | 3 mm | 2 |
The table above indicates that :
It is not recommended to repair a motorcycle tyre more than twice
A tyre with a speed rating below VR can be repaired up to a maximum puncture diameter of 6mm
A tyre with a speed rating of ZR can be repaired up to a maximum puncture diameter of 3mm
When you get a puncture, your tyre can suffer other damage than the puncture itself.
For example, if you continue driving for some time after you have a puncture, this can lead to mottling on the inside of the tyre, making it more fragile.
In practical terms, this means that the cords that structure the tyre inside the rubber have been badly deformed. A visible mottling inside the tyre indicates that these cords have become hot. In this case, the professional will not advise repair because the tyre has become dangerous to drive on.
Tyre sealant kit
Tyre sealant is a type of gel that is introduced into the tyre via the valve to limit the risk of punctures. When the tyre rotates, the tyre sealant spreads over the entire inner surface so that it is evenly covered.
The tyre sealant kit can be used as a preventive or curative measure.
The preventive method is to spread the tyre sealant when the tyre is new in order to prevent punctures,
The curative method is to spray it through the valve to seal the hole after a puncture. Then the tyre is re-inflated with a cartridge from the kit.
The qualities of motorcycle tyre sealants can vary from brand to brand, as can the duration of their effectiveness. You should also be aware that evaporation phenomena due to heat require checking, from time to time, that the tyre sealant has not dried out. If this is the case, it will be necessary to clean the inside of the tyre and re-inject tyre sealant to prolong the protective effect. For proper use, refer to the specifications of your tyre sealant.
