|mike3770||While were on the topic what about 31" Goodyear all terrains? I have them at 28psi right now but should I be higher?|

Please, take JYJeep's advice.

|JYJeep||^^^ do the chalk test.|

Every jeep/tire combo is different, you can do the chalk test or experiment. When I went to 35s on my Rubi I tried 18 to 28 psi.
I like 20 for the ride and wear. I've went up to 24-26 to see if fuel mileage picked up, couldn't tell much if any difference, gets around 15 on the highway. I use 8 psi on the trail and redrocks.

|TJNewbie||I started out with the higher pressure, but the steering felt like I was riding on over inflated beach balls. I dropped it bit by bit and settled at 26 psi with a good contact patch and smooth ride.|

|kluckr||I have had the duratrac for about 8k now and have run 34 psi without any problems nice humm and great even treadware...|

|TJNewbie||which Courser tire is it?|

|nissanman1||I've got a related question, I have Coursers on my Sahara but one has a hole that can't be patched... long story short, to keep from buying a mismatched tire since the AWT is not available I put my Goodyear Wrangler spare one and plan to buy a used cheapo for a spare. Question is: the Coursers have max PSI of 50, the Goodyear has max of 32 psi. Is that going to be dangerous or ride bad. Don't want to kill myself cheaping over a 150.00 tire. but the next full set i get will be more aggressive tread, so i hate to throw money down the drain because the other three are 60% tread|

|InvertChaos||Since you have 30s go with whatever the door frame says. 31-32psi I think|
|01-06-2012 01:10 AM|
|TJNewbie||it depends on the tire, and the weight of your vehical. the 33x12.50x15s run best between 28 to 26 psi on a TJ.|

|suggerdaddy||I thought having lower tire pressure makes it so u have worse mpg|

|suggerdaddy||I have 30's|

^^You should never have to run max. Assuming you have aftermarket tires...For 33's you should run about 30-32 PSI. For 35's, 28-30. If your tires are stock, go by your door placard.
If you really wanna dial it in, do a chalk test. See post #54 in the link below.

And here's a visual representation of how the chalk test works...without the chalk.

|InvertChaos||What tire size are we dealing with? You'll most likely want to be running less than Max that's for sure!|

Is it better to have the max psi in my tires or less
