I assume you mean re-lipped? The barrel is the back part of the wheel. It would all depend what size lip you fitted, currently they have 3 inch lips. Just to give some idea, the following should be a good estimate of what you would get:

4 inch lip: 9.5 ET22
4.5 inch lip: 10 ET16
5 inch lip: 10.5 ET10

etc.
