Re: Tire pressure question

CB, the digital gages tend to be a lot more accurate/consistent than the "stick" type and you can get a nice one for under $30 from Amazon and other places. Many are accurate to a half psi. The one I have (labeled Crafstman surprisingly) can account for different front/back pressure targets and has both a light and a handy bleed down button so if you go over you can expel air while watching the gage. I could never get very consistent results from the "stick". Even the gage on my filler from my big compressor is more accurate that the "stick"!

Like this or u prefer the digital for accuracy?

The reason I bought the digital gauge is my dealer's service department uses the sliding stick kind and after getting my Jeep back from them my tires pressures were always all over the place. As far as digital vs. analog is basically a matter of opinion and your eye sight. I think the digital is easier to read and for me that makes it more accurate.

Re: Tire pressure question

Most stick gages are pretty inaccurate. Remember, placement on the valve stem is important. I use a Monkey Grip circular analog. It seems to correspond almost 100% with the Summit. Now all I have to figure out is what exactly is "cold"? Is it overnight in a 20-30 F degree garage . . . or a 90 degree garage?

Re: Tire pressure question

"Cold" is seasonal..sadly, lots of folks don't adjust their pressure accordingly. The swing is amazing sometimes!

Andddddd, that's my next question.. Obviously, you adjust according to temp, so during the depths of winter, where should they be?

As a side note, my last long drive with 35 in each only want up one pound in each tire to 36 and that's with highway driving around 85 air temp..

Re: Tire pressure question

Yes, I see the same thing happening. I guess 36 and forget it. Obviously, no matter what tirerack says, it is NOT an exact science.

Re: Tire pressure question

Stock pressure is 33psi. I've been running 36psi since we bought it and tire wear, handling and ride comfort are all darn good. Usually goes up to 38 when cruising on the highway.

It's the same, but you'll need to add more air as the weather cools and remove some when it gets hot...

Gotcha.. Well, along the same line of questioning, do you ever air down in heavy snow? I know you do for mud bc you want to ride on top of it, but how about snow.. Also, I was thinking about keeping 35\6 in gear round , good idea or no?

Re: Tire pressure question

I air down for deep sand if needed - but only to 20 pounds. Not sure if this would be good idea in snow or mud. Widening the footprint in sand works great. In mud or snow it might have the opposite effect. In fact, serious mudders often run thin and deep tires.
