Frequently Asked Questions (FAQs)

1. What do foam inserts do for RC tires?

Foam inserts are used in RC tires to provide support and help the tire maintain its shape. Since RC tires are not inflatable, foam inserts are necessary to keep the tire in the desired form.

2. Should I foam fill my tires?

Foam-filled tires have advantages such as increased durability and suitability for most job sites. However, they can be heavier and harder to push compared to air-filled tires. Air-filled pneumatic wheels are lighter and provide a smoother ride.

3. Does WD-40 soften RC tires?

Yes, WD-40 can be used to soften RC tires. By spraying the tires with WD-40 and allowing it to dry for at least 60 minutes, the tires become more flexible and softer.

4. What makes a tire more grippy?

A tire's grip is enhanced by having a dry contact patch area and sipes that allow the tire to flex around obstacles. These factors contribute to increased traction and grip.

5. What are the disadvantages of foam-filled tires?

One disadvantage of foam-filled tires is that the components are often sourced from different manufacturers, which may not optimize the performance of the tire. Additionally, foam-filled tires can be heavier compared to other options.
