Damn I had my tires at 30 psi with the stock rubi tires

 

I know this is a dumb question but when is the right "temperature" to check my pressure?

Last 2 mornings it's been in the low 30s and I check the tire psi before leaving for work and they are showing 36psi at that outside air temp.

I am going to try lowering the psi and see if that helps - but at what psi does the low tire sensor kick on? I don't really want that on all the time.

 

Always check pressures cold. Not sure about the sensor though? I have been told 26 psi is when the sensor starts going off.

 

I think he means the outside temperature, not the tire temperature, I've often wondered this myself. At 30 degrees outside my tires might read 34 psi, at 50 degrees outside, the tires may read 37 psi. Do you need to constantly change the pressure in your tires as the weather cools and warms to maintain the 35 psi recommended?

Also keep in mind if you check when the sun is up you'll get yet another reading. The tires in the sun will record a slightly higher number than the tires in the shade.

 

Keep the pressure in your tires at 35 regardless of temperature. Air is a gas and contracts when cold and expands when heated. The rule of thumb is for every 10° Fahrenheit change in air temperature, your tire's inflation pressure will change by about 1 psi (up with higher temperatures and down with lower).

 

Still not clear - you state to keep temp at 35 regardless of outside temp? I would surely think that the pressure first thing in the morning on a 28 degree morning will definitely be different than an 80 degree morning with an expected temp high of 95...

 

Compared to the 2010 JKUS we just traded in, I have noticed our new 2014 JKUR seems a bit looser on the road. I think a lot has to do with the aggressive tread on the Rubi MT tires versus the milder AT tires on the Sahara. I could be wrong, but I was expecting the Rubi shocks to provide a much stiffer ride than the Sahara, but that's not the case at all. Off road, the suspension on the Rubi is surprisingly squishy and soft.

 

You might want to go to a dealer and test drive a Wrangler similar to yours, compare the handling on the same roads if possible. That might help tell you if something is wrong.

But even new my 2 door handled like crap compared to say. my Firebird or wifes Grand Cherokee.

Not surprising. Tall tires, straight axles, box shape.
