Wheel tires
Tire specifications:
- Inner rim diameter: 2.8" (~71mm)
- Outer diameter: ~125 mm
- Width: ~70 mm
- Typically described as for 1/10 scale Monster Truck RC vehicles
The dimensions may vary +- 10mm with no compatibility issues, remember the tires are made of rubber, they can stretch.
You can always look for different outer diameter tires, but it will change the rover's speed and force (slope/climbing ability). You can as well find different rubber compounds: softer or tougher ones. Keep in mind that softer compounds will affect Leo Rover's turning resistance, but on the other hand, will help it climb obstacles.
Higher outer diameter = higher speed & lower force
Lower outer diameter = lower speed & higher force
It's always a matter of compromise.
