I just bought new Dick Cepek FC II tires they are 305/70/18. I am worried about wearing them out too quickly. The door and the tire say 65psi. Should I run that exactly or less. I had Toyos before this and felt the wore out really quick plus the wore weird from outside in. I was told that it was a tire pressure issue that caused this. Spent a ton on the dick cepek don't want this to happen again.
