Searched, but didn't find anything.

Making a trip to Death Valley next week. Lots of warnings to carry multiple spares (as there's a lot of sidewall damage)... which isn't possible for me.

Now, we've got our share of rocks in Colorado, but Death Valley seems to be a level up. Normally when I'm Offroad I'm at ~17 psi. For these super rocky areas, I feel like it might make sense to stiffen up the sidewall a bit and maybe run 20-25 psi.

Am I thinking about this correctly?. Still rocking the stock BFG K02s.

Old post but deserves a reply. D.V. roads are more about washboard surfaces that beat the crap out of any suspension and passenger car tires. I had no issues on my JLR's KO2's but the Rubi shocks failed quickly from over heating and leaking seals.
Mine didn’t fail… the shocks that’s is. My brain was bruised and I couldn’t think straight. Worse washboard roads I e ever seen… and hundreds of miles of them.

I was just out a Death Valley for 5 days, two weeks ago. I found 15psi was the perfect amount, especially with the added weight of my gear. I had 4 other jeeps with me and a Dodge ram 1500 who all ran the same pressure without any issues. We went through some very rocky terrain.

IMO, the tire thing is more about passenger car rated tires. Your tires will be fine at 17 psi cold, it will still be a jolting experience but survivable haha. My stock JLR blew a OEM shock seal near the Race Track but it did not end my visit, I just slowed way TF down. After installing Mopars lift with the Fox 2.5 shocks and 37's, I've had no issues. Just those two mods made a big difference during many similar excursions.

@LooselyHeldPlans Stiffening the sidewalls makes them more susceptible to cuts, not less. 17psi if probably a great place to have them set.

Been to DV multiple times with different vehicles. I usually run 12 psi. Never had a tire problem there nor have any of my trail buddies.

But Id never wheel without a spare. I’ve seen a person need TWO spares so make sure you have plugs snd sidewall patches.

Also give consideration to load rating/ply for your tires. Are you running C, D, or E?

I was Stationed at Ft Irwin for 4 Years with the U.S. Army and have driven cross country in the Mojave with military wheeled vehicles so I may have some insight as to the spare tire deal. Ft Irwin is just to the west side of the ridge that borders DV, so the terrain, vegetation and weather is exactly the same. We are just the military side of death Valley. It is a smart idea to carry more than one spare if traveling overland. Not only can you get rock punctures but what most people don't realize is that you will get just as many flats from the Vegetation as from anything else. Drive too close to the vegetation and you can get a puncture just like a dagger through jello.
