04moneypit I run 30lbs. on a 230 mi trip (one way) I averaged 17.5mpg. I thought that was pretty good for a lifted aerodynamic brick that weighs 2 tons. But opinions vary.

pismo61 33s I ran 26lbs. and wear was even.Stock 30s recomended pressure is 29lbs.

Hank I don't think that's to bad. I got 19 when it was stock, so if I can 17 out of it I'll be happy.

Buster Hank, on a good tank it is bad...on a bad tank it is I usually avg between 15 and 16.

Hank I'll try the chalk test and I may drop it down to 28psi. Hey Buster what is your MPG like?

Mudweiser For a 33 i usually run 30-35 psi. But with most of my flotation tires sizes i run through water or even the chalk thing and make sure the full foot print is on the ground. Alot of it depends on the weight of the vehicle too. With my Jeep i usually run 15 in my boggers and iroks. Otherwise i wear out the center line of the tread. But every one has their opinions on it.

Buster Hank, 30psi is not to high for those tires. I normally run 28 but when gas spiked earlier this summer, I went up to 30 just to try and help the mpg a bit. I drive about the same mileage to work as you.

Hank Thanks, I'll try to find some chalk and let you know who it turns out.

MR.CLIFFORD Dirt isn't that great of an indicator. Use the chalk method. You will notice a difference.

Hank When I look at the tire with the road dirt on it, I can see about an inch on each side that doesn't look like its touching. Do you think I should dorp the pressure a little more? I'm looking to get the most out of the ride and mpg since I have a 20 mile trip to work one way.

MR.CLIFFORD 30 is close. Just depends on the weight of your jeep. Do the chalk test to see how the tire is riding under normal driving

Tire pressure in a 33?

I just put on a 4inch Rough country lift with 33x12.50 BFG AT's. I was wondering what would be a good air pressure to run for daily driving. I have them set a 30psi and I think this might be to much air. I'm not sure if it will mater or not but I have 8inch wide rims. Does anyone have any suggestions?
