Are foam RC tires good?

Are foam RC tires good?

Foam offers more traction on all surfaces. Foam tires are lighter than rubber. Foam tires have the potential to last longer. They WEAR much better than rubber but they can chunk (piecues of foam getting ripped off) easily.

Why do RC tires have foam?

Similar to air in full size cars, foam inserts are needed to help support the tire carcass from the inside and help it to keep its shape. But, unlike air the insert can be shaped and tuned or made from different materials in order to change its characteristics.

What kind of foam are RC Tires Made Of?

To be extremely general, the foam is neoprene. However, as all things are in racing, there are a ton of different variables that are played with to create all the different versions and specifications that we actually use in racing. Some compounds contain natural rubber, others contain all man-made.

What is the shore rating on foam tires?

Shore (or Durometer) test is the measurement of the resistance of the rubbers/elastomers toward indentation. It has two scales, Shore A and Shore D. Shore A is usually used to measure softer materials, like foam and rubber tires used in R/C cars.

What are foam rubber tires?

Foam-filled tires are OTR pneumatic tires (Bias Air Tires) filled with a type of liquid that hardens inside the air tires and converts the air tires to solid tires.

Do foam filled tires need air?

What are some of the advantages of Foam Filled Tires? They cannot go flat, there is no air pressure inside to leak out. The “air pressure” is fixed and will remain constant throughout the life of the tire. They retain approximately 65% of the shock absorption of a pneumatic tire — softer than solid tires.

What are RC car tires made of?

Wheel rim is made of plastic, tire is made of high quality rubber, with foam insert. Tire outer diameter: 100mm, tire width: 40mm, inner diameter: 48mm.

How hard is Shore A 60?

There are different Shore Hardness scales for measuring the hardness of different materials, such as soft rubbers, rigid plastics and supersoft gels….Some D rated examples.

75 Shore D Hard hat (typically HDPE)
80 Shore D Cast urethane plastic
60 Shore D Golf balls
80 Shore D Paper-making rolls

Do foam filled tires get flat spots?

One of the biggest trade-offs is that foam filled telehandler tires easily take on sidewall damage the same as a pneumatic tire. When the damage is severe enough, the foam will start squeezing out of the tire resulting in a hobbling tire and eventually a flat.
