4.10's should be fine, but if you want to go lower 4.30's would be better suited for 31's. You may want to consider what you may want to do to it latter and decide what to go with. 4.88's are a little low for your application but if you ever decide to go to a 33 inch tire 4.88's are a perfect match for those and 5.29's and 35's would be nice.
