recommended tire pressure

I just picked a set of LTX Defenders in 265/60/18 and curious if anyone has a recommended air pressure. the shop inflated to 40psi and I think they ride a little stiffer than my Lattitudes. I'm thinking about dropping to about 35.

I'm very happy to report that they are quiet; Cannot tell any difference between them and my latitudes which were worn at 30k miles.

Anyone have any thoughts on tire pressure?

Yes. Use Jeep pressures on door sticker.

Re: recommended tire pressure

Greetings,

Based on the recommendation of my Jeep mechanic roughly 3 years ago, I run the front tires at least 2 pounds higher than the rears. The front of the WK2 has more weight. I am running 38 for the front and 36 for the rear.

I have been doing this since I put on my Nokian Rotiiva AT tires back then. Now at 56k+ on them, they seam to wearing nice. I also like the way the JGC handled.

Others here put in different tire pressures based on the type and brand of the tire. Some add more air to get better MPG.

Best for now.

Re: recommended tire pressure

However, I do add a pound or 2 at the start of winter. Remember, all psi's discussed are at 60F. I drive slowly to the convenience store at the beginning of our development first thing on a 60F morning to do this. Other times I assume 1 lb fluctuation per 10F of temperature above or below 60F.

Re: recommended tire pressure

It might hit 60f here at night in December. I'm running 275/60/18 Nitto somethings with 36psi cold(89f?) they're showing 38 at 93*. They sit nicely and ride better than when installed at 40/42. Stock tires I ran 35. This can be boiled down to absolute fact but it really is subjective unless you go above or below logic. While we're at it can we discuss leather treatment?

Re: recommended tire pressure

I apologize for the hijack, but...

One thing I've always noticed is a discrepancy between tire pressures listed for WK2's. I have an overland diesel, off-road 2 on 18's and it lists 33/33 on the door. I've noticed most other members here say theirs is 36/36. What bumps it down to 33? 18's? Diesel? ORA2?

I believe 18s are 33psi and 20s are 36psi

Re: recommended tire pressure

Tire pressure is definitely something I play with using the cold recommended as a starting point. I never tow, never really have a heavy load and rarely even have more than 2 in the car at a time, so I usually run a bit below the recommendation, with less pressure in the rear due to decreased load on rear axel.

Remember, Jeep has to cover liability, they have to provide you with a door jamb tire pressure that reasonably covers most situations, empty to fully loaded down with people and luggage, as well as play a balance between fuel economy and comfort. So start with their pressure and tweak them down until you feel comfortable. Some people prefer the stiffer ride of higher pressure, others don't. Key is to keep your contact patch at maximum/uniform so the tire can work as designed. Too high and your running on the inner portion, too low and you are running on the outer bands of the tread.

How do you like the Defender LTX on the grand? I just put a set on my Wrangler and really like them, they are a bit rugged so debating on these or the LTX premier for the grand since its a street crawler.
