We choose tyres larger than off road wheel brands in order to have greater traction and travel further off-road. You are now looking for a toy with an aggressive tyre tread pattern and a larger footprint to gain greater grip. For all-wheel drive, tyre pressures should be reduced to 20 psi. As you increase tyre size, you can see that the footprints become noticeably broader and longer. You can travel farther off-road thanks to tyre tracks. Tractors have large back wheels, tanks, and Escalader has full-length tracks because of this. It aids with stability and traction.
