RC tire foam gives a nice boost to your RC. But it is really annoying when you need to change the tire foam frequently, right? Then again it is really painful to dry them up when the foams get wet.
So, how can we skip these troublesome procedures? By looking for alternatives.
Now, what can be the RC tire foam alternative?
Hair donuts foams and air pressurized tires can be great alternatives for RC tire foams. Hair donut foams are totally different in appearance and texture from normal foams. Another popular option is air pressurized tires. Air pressurize tires contains air instead of foam inside. But both have pros and cons.
Now let’s dig deeper to see which alternative is best for you!
Why Do You Need Tire Foam?
The RC foam insert is the single most important determinant of how well your RC tires operate. Because an RC tire does not use air pressure. So, to keep it in its form, a foam insert is required.
Unlike air, which maintains the same pressure across the inner of the tire in all directions. A foam insert can have high-pressure and low-pressure areas in the tire.
This may and will cause an RC tire to respond differently at different spots along its length. As a result, it’s critical to work with and understand your tire foams.
Sometimes this foam comes out of the tire and renders the RC vehicle useless. In that case, you may want to look for alternatives to this foam.
Now, let’s take a look at the types of RC tire foams!
3 Different Kinds of Foam for RC Tires
Before looking for alternatives let’s take a look at different kinds of foams that you can use in your RC tires.
There are basically 3 different kinds of foams you can get for RC tires. The requirement of the foams generally depends on the budget and your need.

The most common type of RC foam inserts is regular foam. They have square corners and are flat on the front.

Foam inserts with two stages are called dual-stage foam. These have square corners and a flat surface. These help the wheels of your RC car from getting wet.
Here are some of our favorites when it comes to dual-stage RC car wheel foams:
It is common to have a harder foam band on the outer edges. And a softer one in the center. Some mattresses feature a harder inner layer and a softer outside layer.
Another type of foams that you can see inside RC car wheels are the foams that have been molded.
The foam insert’s face is sculpted to look like the interior of an RC tire. These foam inserts are also molded to meet the sidewall curvature and rim ridges.
These foams are a little more expensive, but they allow you to reuse them. The ability to reuse helps to mitigate the greater price.
