My point exactly. I always go with doctor's recommendation. I also go with Jeep's recommendation for the same reason ... especially on OEM tires.

The only problem is Jeep doesn't build tires. Anymore than your doctor does.

This is good stuff and a shame at the same time...

Re: What Tire Pressures Do You Run?

Billt,
It almost seems like you wanted people's opinions only to go against what everybody is saying on purpose. I guess I'm just not seeing the point of this thread as you clearly seem to know more about tire pressure than what the manufacturer of your Jeep does. So why ask all of us? i have always gone about 2 psi above what the door sticker says. I would never run at the max rated psi because that just seems stupid to me, but that's just my opinion.

Re: What Tire Pressures Do You Run?

I used to run my factory tires at 35-37psi all around. Overtime I bring it into service they fill them up to 45 psi, no matter what time of year.

That's weird that a shop will overfill your tires. Discount Tire which is the only place I would ever let touch my vehicles for tire service fill only to recommend pressures.

Re: What Tire Pressures Do You Run?

The door says 36 psi when cold. I typically set mine to 39 psi cold. The weather changes enough here in New England that I set it a bit higher so that the tires do not fall below the minimum if/when it does cool off at night.

I simply asked what pressures you run, not for opinions on why others shouldn't run what they do.... Or what "seems stupid" to you. You're chasing everyone around the thread, trying to convince them they're overfilling their tires, if their preferred pressures are higher than yours.

What are your tires rated, and what pressure do you run in them?

Also, this is the first vehicle I ever had that has tire pressure monitors. How do they work? Does the valve stem send a signal to the car? I see a lot of the tire stores offer "rebuild kits" for them when you buy new tires. They're quite reasonable. Do they have a small battery?
I run at 37 PSI on my Yokohama Parada Spec-X (295/45/20's). Smooth ride, nice and cushy over bumps. Then these get taken off for some snow tires in the winter (which I have not decided on yet). Not sure if I would run the same PSI or go higher for those...

The TPM's in the tire are at 499Hz and updates the EVIC very quickly after making any adjustments to the PSI. It says within 45 minutes but I find that the system quickly updates.

I thought you were the only one that runs the tires at max rated PSI in this thread? The only other person was someone who said a shop put them there. Either way it's all good. I was just under the impression that the side wall max rated psi was not what you want to run at normally because it's just that...maximum the tire was designed to run at. I personally wouldn't want to push a tire to its max on a regular basis especially during the summer when it's easily going to increase 4-5psi when hot.
Again, I have no proof behind my statement, but considering what the people that designed and built my Jeep say to do is good enough reason to me not to run a tire at its max designed pressure.

Fair enough. I've had several tire places fill all of my tires to max. cold pressure over the years, after having a puncture leak fixed, etc. A few have told me it's their standard practice, because they see so many tires come in severely under inflated. Usually from a lack of attention more than anything else. I'm willing to bet if a 1,000 vehicles were pulled over and had a spot check done on tire pressure, far more would be under inflated, than over inflated.

I do it because as I said, 45 years of driving has convinced me I get better fuel economy, as well as the longest tread life doing so. I also like the handling and firmer ride it gives me. If this was "dangerous", or in some way causing undo premature failure, I would think I would have seen it by now. Especially living in one of the hottest areas of the nation.

Just curious, since you are in such a hot location, what do your tires end up going up to with them set at 44/45 psi cold? Those things have to see 50psi eventually right? assuming you aren't running nitrogen.
