Ok here is my deal. I just had smaller tires put on my truck and my speedo is off my 14.9% by maita's tire site. I have called around and cannot find anywere to get it fixed. The only place i have not checked is a chevy dealership but i am going to call them tomorrow. Does anybody know who or what i can do to fix the problem? I have a 2000 chevy s-10 with a 2.2 in it.
