Car Tire Issues

I have my car all set up and everything and it works fine. im using a wheel alignment script to align the car tires to the orientation of the wheel collider. the issue im having is that when my car reaches a certain speed either both rear or both front tires jumps in the air depending if the car is front or rear wheel drive and i dont know why they are doing this.

Due to the high speed, the wheel raycast is hitting the car and moving the wheel up to the 0 point. You can fix this in 1 of 3 ways:

1) set the car body in the ignore rays layer

2) place the wheel colliders outside of the car model collider

3) alter the alignment script so that the offset is never less than the wheel radius (so it wont jump up beyond the minimum suspension position)

To keep your vw tire good, you have to check the vw polo tire pressure every week.
