Tire Cheat/Glitch
This may require some patience to get working.
Step 1:
Enter atleast two seperate vehicle cheats so you can have quick access to them through the cheats menu on the phone.
Step 2:
While holding forward alternate between the two cheats. This often works best on angled environments.
Effect:
Typically it effects only the front wheels, however it rarely works on the rear wheels. You will notice, if done correctly, the vehicle has a somewhat melted/streched tire which repairs itself when you enter the vehicle.
