Another gearing Q?

Can someone help me out?

I have an 03 5sp 2.7L 4x4 with 3.91 factory gears - mated to tiny factory 28" tires.

In the next 2 weeks i'm going to upsize my tires, and regear the truck.

I have a Cornfed 3" lift.

I Guess my 2 options are 33x10.5 or 33x12.5 - I already have 15x8 black steelies with 3 3/4 backspacing. I'd like to go with a procomp tire, they currently have the buy 3 get one free - and I can get free shipping as well.

Should I go with 4.88's? I am going to add a lockright in the rear at the same time. I don't wheel very often, at most just a few weekends a year.

Thanks again for the help, this in going to be an expensive upgrade session, and really want it all to work well together.

Or would it really be better to just do a 32x11.5 and 4.56's?

I'm running 4.88's with 33's on my '99 4Runner with the V6 and 5spd. I think the few extra rpm's are needed b/c of all the extra weight and drag added by the offroad parts.
How are the 4.88's working out now that you've had them a little longer?? I'm still on the fence...But as you mentioned, the extra weight makes a difference..The only real concern I have about the 4.88's are the highway rpms..I've done all the gear calculations and for the most part I'd be about 3100 at 70mph..
