What can you put on tires to prevent dry rot?

What causes tires to dry and crack?

Tires naturally degrade over a period of time because they’re made from rubber. When a tire ages, it loses the protective resin which keeps the rubber from oxidizing and drying out. As those oils evaporate, the tire becomes brittle, and starts developing cracks and begins to break apart.

Is cracking on tires normal?

Tire – cracking is common on tires that don’t get driven that much, like trailers, motorhomes, classic cars, collector, performance cars, grandma’s, and the church van. That’s because tire rubber contains antiozonant, a chemical additive that slows tire cracking by protecting it from harmful UV rays and ozone.

How do you rejuvenate old tires?

How to Restore Old Car Tires

  4. Add another layer of gel if you want a shiny or glossy appearance to your tires.

Is it dangerous to drive with cracked tires?

Visible cracks between treads, or anywhere on the tire is a dangerous situation to be in. These are commonly referred to as dry rot. This also happens next to the bead surface adjacent to the rim.

Why do tires crack on the sides?

Oils and chemicals in the rubber compound start to evaporate or break down because of UV exposure. The rubber loses its flexibility and begins to crack at the surface, and the structure becomes more and more brittle (think of a really old rubber band), leading to sidewall damage and eventual failure.

How long should Tyres last before cracking?

Cracks on the sidewall are a sign that the tyre is ageing. This can mean that the rubber is becoming stiffer so the tyres won’t absorb shocks as well and you may be risking a blow out at speed. Generally speaking, tyres should be replaced when they reach five years old.
