4.10 or 4.56 - Opinions?

Hey everybody, I have a manual 98 XJ with 31" tires and I am definitely in need of some regearing. I'm sitting on the stock 3.07s and am getting passed by every 18 wheeler on the highway with 13mpg to boot. I was wondering whether I should get a set of 4.10s or 4.56s with plans of going to 33" tires in two or so years. I drive on the highway a whole lot but do wheel it a good deal too. So what do ya'll think?

i dont now about the 33's but with 31 a 4.10 would be great, maybe the 4.56 would limit your top speed, but not sure of it

with the 5spd, 4.10's would be ideal for 33's and a little on the low side for 31's. 4.56 would be way too deep for 31's with a 5spd.

Completely stock, and keeping it that way...

X2. With the auto 4:56's are perfect for 33's, but with the manual 4:10's will be plenty. If you were staying with 31's you could go with a set of auto axles that are geared 3:55 and be fine.
