Default 4.56's and 32" tires?

First the background, its '97 TJ with 4.0 and Auto 3 spd tranny, I currently have the very pathetic 3.07 gear ratio. Just realized my rear pinion shaft has excessive slop, hate to put money into rebuilding the dana 35. I currently am running 32" tires, I plan someday down the road to run 34" or 35". This is strictly a trail toy, I put 3000 driving miles on it last year 95% of which is offroad in the trails around Rose City and St. Helen. I do flat tow it behind my motorhome also.

I definately need more gear, was planning on 4.10's but found a deal on a pair of axles all set ready to bolt in (rear is a 44) but they have 4.56 gears. With having to do axles now my flat fenders and 34" tires will be atleast another year off. Looking for opinions on how bad it will be running 4.56s with the 32's??

Am I going to be able to do 55 mph into town to get gas?

with as little as you drive it on the street you will be perfectly fine. The only place you would have a problem anyway is trying to run 80 mph down the freeway.

I would do it. Just don't try to drive it on the e-way.

Like the others have said, you're gonna lose some top end, but it should be fine.
