Street tires vs. off road tires

[OurJeepLife]

We've been torn between street and off road.. Feeling that we may lean more towards the off road and loose the MPG's in the long run. But lifting is out of the question. So we may considered getting a cross over tire similar to the Michelin LX A/T2 series. Although we are keeping the same general size, we are getting a bit wider tire.. at least to keep a bit more on the road. I just want to know that the tires we get are going to last as well as preform "if" we venture off road again.

I would go with an MT that is less agressive and has a more even tread pattern. This way you get a decent ride and still have a pretty capable tire. Something like the Hankooks I have or the Firestone Dest. M/T, or the Nitto Trail Grappler M/T. These are a bit quieter than something like a KM2 (which I love) or some others.

Not quite relavant to the last post but....

Earlier in the thread the topic of different size tires make a difference on the calculation of MPG. Just wondering if this is a proper way to calculate the difference.

The original tires did 682.75 revs/mile.
My Tires do 638.1 revs/mile.

My current MPG on the dash reads 15.1.

15.1 x 682,75 (what size tire the Computer thinks I have) = 10309.525 (Total revs for 15.1 miles the computer counts)

Now divide this by what I actually have : 10309.525 / 631.1 revs per mile = 16.15 MPG.

Does this sound like the correct procedure to the the Mathmatically inclined? I guess I could express it as a ratio as well which would be 682.75 / 638.1 = 1.069. I can use this number multiplied by MPG to get the correct reading I think.
I have the 4.7L Flex and a lift. Does this sound right for what I have?

The 16.15 is city driving in Houston. I get about 17.7(dash readout) which would be 18.5-19ish, according to the math, on the HWY. (Staying right on the speed limit.)

Seems we have the same set up my math has my display 2mpg under what it really is. That being said I don't get know where near your numbers bro with the correction I'm looking at 14MPG country roads display says 12MPG.

I got the revs per mile from discount tire's tire size calculator which seems to be wrong for my tire (since the size isn't always exactly as stated). Hankook actually claims that it is not 631 revs per mile but actually 651 which actually puts my milage closer to only .5 off instead of 1. That's by my math which is actually more dissapointing because it means i'm only getting 15.6 in the city. Could be worse I suppose. My moms Yukon only gets 13 in the city and it has normal tires.

How did you figure your's out?
