You can fix your cracked tires with sealants when the cracks are small and not obvious. To ensure this method is done right, you need to buy a sealant that’s suitable for your tires.
Yes, cracked tires can be repaired, but primarily for appearance. The issue can be masked but not repaired. There are fillers on the market that make it easy to fill the cracks in a tire’s sidewall on your own. It is something to consider if you deem the cracks unsightly and they are only harming cosmetics.
Is it illegal to have cracked tyres?
Cracked or damaged tyres are not necessarily illegal – but they are dangerous for you, your passengers and other road users. If the tread doesn’t reach the legal limit, then they are illegal. Small tears and wear and tear should be addressed immediately before they create a more serious problem.
Do I need to worry about small cracks on my tyres?
Whether you need to worry about these cracks depends on where they are and how severe they are. Small cracks on the tread blocks of the tyre are a sign of normal wear and tear and aren’t generally anything that you need to worry about.
What are tire cracks?
Fun fact, tire cracks are roughly orthogonal to the strain axis, so examining the cracks can give you an idea of how forces in the tire work and also which are most problematic. Cracks in the tread itself are not hugely distressing in terms of tire failure but will result in less traction.
Can a tyre crack cause a blowout?
In many cases, cracking can purely be on the surface and relatively superficial. However, there can also be a more sinister type of cracking which goes deep into the inner part of your tyre, compromising its integrity. Cracks that go into the inner, or structural, part of your tyre increase the possibility of a blowout.
