No spare tyre – puncture repair kit

  • Author: OPONEO.CO.UK

Car and delivery truck manufacturers are replacing spare tyres with puncture repair kits, etc. more and more frequently.This allows them to save time and decrease the vehicle's weight.On the other hand, owners of cars with LPG systems, where the LPG tank replaces the spare tyre, try to find an alternative to carrying a spare tyre in their trunk.

For the last couple of years, car shops have been offering spray-on tyre sealers and puncture repair kits that include a sealing agent and a compressor.

The compressor puncture repair kits and spray seals are both moderately effective and both allow for driving at moderate speeds, e.g. to reach the nearest tyre repair shop or your home.You should also bear in mind that the tire repaired using such spray seal or kit may not be suitable for repair.Many tyre repair shops will not do it.And in the event that a repair is unsuccessful, you have to buy two new tyres.Why two?Because both tyres on one axle should have the same type and the same tread depth.It is better to replace all four, especially in 4WD cars and cars equipped with ESP systems.

Huge differences in effectiveness
It turns out, that tyre repair sprays cannot be recommended, as they are only able to repair very small damages, and their instructions are too brief.Moreover, they can fail completely in low temperatures.

Tyre replacement after using puncture repair kit.

The puncture repair kits consisting of a sealing agent and a compressor (air pump) are much better.There are, however, huge differences in their efficiency.In the ADAC study, five kits were rated as good, two as sufficient, while three products were rated as insufficient.Premium Seal Repair, whose micro-phase sealant was able to repair even bigger punctures, was a winner.The device had a concise manual, and it could be disposed of in a normal trash can after it was used.The compressor, on the other hand, turned out to be too weak and the testers complained about faulty manometer readings.

All puncture repair kits allow for further driving to a limited degree – you can only drive a limited distance at moderate speeds.They also cannot repair larger damages, tread damages or sidewall or valve stem defects.

An alternative for the spare tyre?
Both spray seal and puncture repair kits cannot fully replace a spare tyre, even a limited use tyre.This is not compensated by lower fuel consumption (thanks to lower weight), nor by additional space in the trunk.Run flat tyres are an alternative solution. They are constructed to allow you to drive as far as 150 km (at the speed of up to 80 km/h), even when the pressure is gone completely.

To avoid any damage to your tyres, ADAC recommends using the tyre pressure control systems.They allow you to notice the tyre damage right away, before a breakdown happens.
Nothing will replace a spare tyre, but if you have no space left for it, e.g. because of the LPG tank, you have to use alternative solutions, such as seal kits or spray seals.Cheap, ineffective tyre sprays can be bought for as little as 10 Euros.Puncture repair kits with compressors are much pricier - they cost from 30 to 115 euro, while the refills (to be able to reuse the kit) may cost as much as 40 euro.Some kits are disposable.
