anything I can do about this? It wont stay straight no matter what I try with the air pressure in the tires, have razr tires on there, thanks

 

The first thing you need to check is if the axel is square with the frame.

The next thing to check is stagger of the tire. Take a flex tape or a string and measure around the tire to make sure they are the same size. Most likely it's a stagger problem.

You can also swap the tires and rims from one side to the other to see if it is a stagger problem.
