Tire Pressure Suggestion???
 

Howday alll

I'm having a set of 31x10.5x15 BFG A/T KO's installed today on my '02 TJ.

Can someone make a recommendation for a tire pressure for snow and ice
covered roads. I drive 50 miles a day round trip to work on highway so I
don't want to kill my already wonderful gas mileage. (Note Sarcasm!)

Another question while I am at it...going from 30's to 31's is it necessary
to change the spedo gear or should I just take my gps out and see where it's
at?

Thanks Much!

Re: Tire Pressure Suggestion???
 

For snow and ice-covered roads, you want to make sure the tires are not
underinflated which would increase their footprint size. That would make it
harder for them to dig through the surface snow to better traction below.
The smaller footprint is important, and is why in such areas, tall skinny
tires are what work best.

I would try 33 psi or so, or as high as the pressure can be taken that still
leaves the edges of the tires barely touching the surface. A business card
should fit under the edge but when on a concrete (smooth) surface, you
should not be able to insert it in more than about 1/4".

Hi Steve:

Factory door sticker on my '02 TJ with the factory 30" tire group says 29
pounds. I put 31 x 10.5 x 15 BFG AT's on over a year ago, and have been
running 28 pounds all year. Seems fine for both winter and summer. No
unusual wear patterns at 28 pounds.

I used my GPS to check my speed after installing the 31's and it is almost
perfectly accurate. The speedo was reading a little fast at any given speed
with the original factory 31's. You probably won't have to change a thing.

Also, check for rubbing at full lock turns. My 31's do not rub at all, but
some do. If so, it's an easy steering stop adjustment you can see here:
