At 65 feet you don't need to oversize for distance, so your hots and neutral should be run in #1 AWG copper. The ground wire is #8. Oversizing will only help if you plan to have very heavy loads running for extended periods of time, over time heavier wire will save a bit of power usage.

Just to be sure:
when you said "outside wire" did you mean to infer a direct buried cable? or simply that it was outside?

The #1 is the size if you are using UF. If you use other types of wire, the size may very well be different.
