advice on gears and tires

[greenie]

Hay needing some advice from the pros. I have a 98 tj with 2.5l 4 cyl
With stock gears and tires and I was wanting to run 32x11.5x15 but
not wanting to lose to much power and not lose any mph if possible
would a gear change to a 456 gears help or hurt it's a 80 mile a day
daily driver through the ozark mountains which are pretty steep and
crooked I am also getting 20 mph currently and don't want to hurt that.


Thanks
Greenie.

If you don't want to lose any MPH, or MPG, then don't put the bigger tires on it.

When you add a lift kit ad a set of bigger tires on a 2.5L, you are going to lose somewhere.

The bigger tires, add more weight and rolling resistance, which will cut into the MPG, doesn't matter what gears you choose.

4.56s are a good choice to get you close to stock numbers as far as ratio goes, but the MPH,and MPG numbers are going to change.

You can't have a cool looking ride without sacrificing something in return.
