also, there's nothing wrong with starting in second. it's not like there are rules about always having to start in first. you'll love that extra leverage of first every time you're hauling anything heavy.
also, also, if I remember right, 3.73s and 31s are the exact same as 3.07s on stock tires so 4.10s is only 1 step up from that (and the rule of thumb is that you want to go one step more to accommodate the extra weight of the bigger tires.)
