Tyre Sealant; Pros and Cons

Tyre Sealant comprises of a carefully formulated blend of natural fibres, blocking agents and sealing compounds that’s been proven to seal a puncture of up to and above 18mm.

How tyre sealant works

Pros of Tyre Sealant
1. It's a fast, convenient, and affordable DIY solution.
Many tyre sealants come in a pressurized can and are easy to apply. When you spray the product into the valve, the tyre inflates and the formula coats the inside of the tyre, plugging leaks or punctures. Within a few minutes, you can start driving your car so the gel spreads evenly.

Even with more major flats, a good sealant will fill up your tyres enough to drive the car a short distance, like to the side of the road. That way, you can get out of the way of dangerous traffic and reduce the risk of harm to you, your passengers, or your wheels. It's a safe option if you don't have a spare tyre.

2. Tyre sealant may prevent flat tyres.
Sealants are most associated with fixing tyre punctures, but using them for preventing flat tyres is often overlooked. "Preventative tyre sealants are particularly helpful if you live in a more rural area where there is a lot of gravel or rocks, or if you tend to be around job sites, where nails and screws routinely find their way onto the road and driveways," he says. "Using a preventative tyre sealant is an easy and affordable way to give the tyre an extra layer of protection and help prevent potential punctures that would cost you more money down the road."

3. Sealant may prolong the life of old tyres.
Tyre sealant doesn't need to be applied only in the event of a flat tyre. Some people use sealant to fill in age and wear-related cracks in their tyres to keep them running longer.

Cons of Tyre Sealants
1. Tyre sealant may damage — rather than fix — your tyres.
It may be simple to use, but when applied incorrectly, tyre sealant may further ruin your tyre. Sealant is designed to disperse and fill up puncture holes while aided by the heat of the tyre. If it doesn't warm up fast enough, it can pool toward the bottom of the tyre and lead to potential wheel misalignment. 
Tyre sealant may also damage the sensors inside your tyre, keeping the pressure constant and failing to alert the driver inside the car if the tyre pressure was to actually become low.

2. It's not a permanent fix for a flat tyre.
Leaky tyre sealant has been known to corrode wheels, which can be costly to replace. Plus, no tyre sealant is a permanent solution. In fact, you may need to buy a new tyre to replace your flat because many service centres won't repair a tyre treated with a chemical sealant.
Sealants may contain hazardous chemicals, and removing sealant may be time-consuming for a repair person. 
Using a canned sealant can increase the pressure inside the tyre, too, risking a blowout or injury to the person who's repairing the tyre.
