I am having trouble with changing my tires. I have a R89C Race Car. I changed my tires to sport hard for a B-Spec Race, but now I am trying to use it in the extreme series. I am getting left in the dust. I am selecting my car and going into tuning and selecting tires.... it shows me what tires are available but when I click on them it gives me a descripiton but doesn't change them. What am I doing wrong?? Please help.
