Increasing traction on plastic wheels can be done in a variety of ways, depending on desired outcome and constraints such as cost and weight. One method is to increase the friction between the wheel and the surface it travels on by widening the tires or increasing their radius, thus maximising contact and friction. This can be achieved by repurposing tread from old bicycle tires, which have grooves that grip the road, providing more control. Alternatively, a soft material such as rubber can be coated onto the tires.

What You'll Learn
Increase friction between the wheels and the track
Increasing friction between the wheels and the track can be achieved through several methods, some more complex and permanent than others.
One of the quickest ways to increase friction is to roughen the surface of the track using sandpaper. This will provide more grip for the wheels, especially if they are made of plastic, which typically has less traction than other materials.
If you are looking to modify the wheels themselves, there are a few options. Firstly, you can increase the surface area of the tire that touches the track by widening the tires or increasing their radius. This will increase the contact and thus the friction between the wheel and the track. You can also add weight to the vehicle to increase the force of friction.
Another approach is to coat the tires with a soft material, such as rubber. This can be done by repurposing tread from old bicycle tires. Cut strips from an unused bicycle tire and wrap them around the existing tires. Alternatively, you can apply a synthetic rubber coating to the wheels using a small paintbrush. Allow the coating to dry for several hours before applying a second or third coat to build up a durable layer. You can also create off-road tires by sprinkling fine-grain sand on the wet rubber coating.
It is important to note that increasing traction on plastic wheels can put more stress on the motors and linkages, as plastic wheels are designed to slide. Adding too much traction can cause a bind on the motor, so it is important to consider the power and weight of the vehicle when making these modifications.

Use a soft rubber coating
To increase traction on plastic wheels, one method is to use a soft rubber coating. This is a cheap and easy way to add grip to plastic wheels. The process involves applying a liquid rubber coat or seal spray to the wheels. It is important to prepare the wheels before applying the coating by cleaning them thoroughly with soap and water, and then allowing them to dry completely. Once dry, a thin layer of synthetic rubber coating can be applied with a small, soft-bristled paintbrush. It is important to note that the rubber coating may take a while to dry, and it is necessary to wait until it is fully dry before using the plastic wheels again.
There are a few different ways to prepare the wheels for the rubber coating. One method is to use duct tape to cover any cracks or holes in the wheel before applying the rubber coating. Another method is to use a fiberglass kit to fill in any cracks in the plastic wheels, and then apply the rubber coating on top. It is also possible to use glue on the tires and then wrap them in duct tape before applying the rubber coating.
When applying the rubber coating, it is important to ensure that the work area is covered to prevent any spills. It is also recommended to wear a respirator to protect against any lung or airway irritation from the fumes of the rubber coating. The rubber coating can be applied in thin layers, and it is important to allow each layer to dry completely before applying the next.
Once the final layer of rubber coating has been applied and dried, it is possible to add extra grip by sprinkling fine-grain sand on the rubber coating. This will create a rugged, off-road tire effect. Overall, using a soft rubber coating is an effective and inexpensive way to increase traction on plastic wheels.

Widen the tyres
Widening the tyres on plastic wheels can be an effective way to increase traction, but it is not the only method. There are conflicting opinions on whether wider tyres provide more traction. Some people argue that wider tyres provide more traction because they increase the surface area in contact with the ground, which increases friction. This is especially true if the tyres are made of a softer, grippier compound, as a wider tyre can accommodate a softer compound without wearing out as quickly.
However, others argue that tyre width does not change the contact area, but rather the shape of the patch. They claim that tyre pressure is what affects the size of the patch, and that an infinite tyre width would require infinite psi, resulting in almost no contact with any surface. Additionally, if the tyres are too wide for the vehicle, they may have less traction and a higher chance of aquaplaning.
There are several ways to widen tyres. One method is to cut and attach a bicycle tyre to the existing tyre. This can be done by cutting the sidewalls off a bicycle tyre and gluing or screwing it onto the plastic wheel. Another method is to cut slits in the sidewalls of the bicycle tyre, "splay" them out, and screw them into the plastic wheel. It is important to check the clearance on the front steering when turning.
Widening tyres is not the only way to increase traction. Other methods include roughening the surface of the track, using a different type of material for the tyre such as PU, adding weight to the vehicle, and increasing the radius of the tyres.

Increase the radius of the tyres
Increasing the radius of the tyres is one way to increase traction on plastic wheels. This approach increases the surface area of the tyre that touches the ground, thereby increasing friction.
One way to increase the radius of the tyres is to wrap strips of rubber or flattened bicycle tyres around the existing tyres. This method has been used by users of Peg Perego John Deere Ground Loader toy tractors, who have reported success in increasing traction by wrapping strips of bicycle tyres around the plastic wheels.
Another way to increase the radius of the tyres is to invest in rubber traction bands specifically designed for power wheel tyres. These bands conform tightly to the tyre, increasing both traction and control. They are simple to install and do not alter the vehicle. A similar option is to use a rubber coating spray, which can be applied directly to the tyre to increase grip. However, this method may need to be reapplied periodically to maintain optimal performance.
It is important to note that increasing the radius of the tyres may put more stress on the motors and linkages. This is because as traction increases, the torque on the motor also increases. As a result, it is important to consider the trade-off between traction and power when modifying the tyres.
In addition to increasing the radius of the tyres, other methods to increase traction include adding weight to the vehicle and using tyres with a wider width. These methods can also help to increase friction and improve the vehicle's performance on various surfaces.

Add tread from old bicycle tyres
Adding tread from old bicycle tires is a great way to increase traction on plastic wheels. This method is affordable and easy to do, requiring only a few tools and materials. Here is a detailed guide on how to do it:
Preparing the Bicycle Tires:
Start by choosing an old bicycle tire that is still in good condition. You will need to cut the tire to create the tread. Use a pair of scissors or wire cutters to cut the tire, depending on its construction. Cut off the sidewalls and create slits every couple of inches, splaying them out. You will need enough tread to wrap around the plastic wheel, so measure the circumference of the wheel and cut the bicycle tire to size, giving yourself a little extra to work with.
Attaching the Tread:
Begin by drilling pilot holes into the plastic wheel. Use a drill bit that is slightly smaller than the screws you will be using. You can use outdoor screws made of stainless steel or galvanized metal. Black screws will blend in well with most tires. The screws should be around 1 inch long and 5/32 inch in diameter. Secure the start of the bicycle tire tread to the plastic wheel using these screws. Then, tightly wrap the bicycle tire tread around the wheel, ensuring a snug fit. Drill additional holes and insert screws as needed to secure the tread in place.
Final Steps:
Once you have wrapped the entire tread around the wheel, use scissors to trim any excess tire material that is overlapping. Be sure to check the clearance on the front steering when the wheel is in full rotation. You can also use Gorilla Tape to further secure the tread and reduce bounce and noise on concrete surfaces.
By following these steps, you can effectively add tread from old bicycle tires to increase the traction of plastic wheels. This method will provide better grip and allow your ride-on toy car or tractor to navigate a variety of surfaces more easily.
