Thanks for the input. I'm going to start with your suggestion and see how
things work. Most likely will try to find some middle ground between your
suggestion and Tom's. The town where I work does a great job of plowing
the streets but a lousy job of applying sand or salt so the place is a
skating rink.

Tom

Thanks for your input too. I found a calculator somewhere on the net this
morning that calculated when changing from 30's to 31's resulted in 55mph
turning to 56.something mph. Not enough of a difference to mess with
changing speedo gears

Thanks again Guys!

Steve: Hi Jimmie Here. Just one state below you here in IOWA. Hey my
brother John run's 28 P.S.I. in his T.J. 2ooo and I looked at them this
Friday and it's sure looks like he could stand to run them at 25 P.S.I.
You have to remember that Jeeps don't hardly weight anything. I've seen tire
dealers put in way to much air because most vehicle's weight in more than
Jeep's, CJ 's ,YJ 's and T.J's do. Back when I was running 31's on my C J.
I always ran them at 25 P.S.I. Heck I 'm running 33= 12:50= 15's on her now
and I run them at 18 P.S.I . I run them at highway speed's and in town and
have been for about 3 1/2 years or so and they are wearing just right. In
fact I'm always getting people asking me how I get all the mileage out of my
tire's and it's all in the air pressure. If you start out at 25 P.S.I you'll
be glad you did. If you try it you'll see with I mean. It is way more
important to run higher pressures in vehicle's of heavy weight's and also
narrower tires do give better snow traction on most unit's.
Good Luck; Jimmie; V.P. North Iowa Off Road Club

CJimmie

Thanks for the input. I still have't taken the time to see what Sam's put
in them for pressure. We're getting all kinds of snow today....It's pretty
easy to finds all kinds of "errands" that need to be done when you have
brand new tires and brand new snow! :-) I am completely amazed at how well
these things ride that the 30" GSA's that came on the vehicle.

Where is the North Iowa Offroad Club based out of? I'm in Rochester.
