tires for sand

[franklin2]

A heavy diesel truck is already handicapped for sand driving. Big tires and lightweight are the key, the reason they use those Cherokee's out there in Utah.

As soon as I hit sand I slow down and sink. I need flotation devices. Lol

Even big tires will sink if not aired down. What do you have for wheels and tires now?

I'm running 235 85 16 tires. I aired down to 35 lbs and man what a difference. like I had coils springs up front. The fronts were at 90 psi. My wife even liked the ride. No rattling too. Will get on some sand today.

My first thought when you said you were at 80 psi was man that’s got to be a stiff ride. I normally shoot for 50-55 all around, and only air up the rears if I’m loading a bunch of weight in. I think you’ll see a little improvement at 35, but lower may be better. If you don’t have some kind of compressor to bring along, it’s going to be a balance between sand and street. A wider tire would really help a lot though. The other thing about airing down for sand is treat it like 4wd. That is to say, don’t wait until your stuck to air down.

35 psi will be better, but you will need to get in the 15 psi range before it is really noticeable

I'm running 235 85 16 tires , I live on the beach and have deep sand, I have had to go to under 10psi with my 4x4 to pull a small trailer out on a flat incline in a deep sand area.

Also fwiw
Sand is like snow in that there are several "types" take note on the terrain and how it reacts.
But do HAVE FUN

Yes. This is very true.

Have to remember that I have to drive on the road most of the time. I think 35 is where I'm going to keep it for a little while. So as I was airing down, I broke one of the valve stems. Not the stem itself, but the core inside. Either I find some cores tomorrow or I have to bring it in to be replaced Monday.

Cores can be had at any parts store or tire shop. If you end up getting bigger tires I am running 285/75R-16 and they are quite wide, 33's, and come in all sorts of A/T or M/T varieties.
And in order to have good wear for just pavement driving I'm at around 32psi front and <20 psi rear. So with these pressures and wider, taller tires you might have decent results for the hybrid driving.

It is ******* tires running them too low on the street. Really need a way to air back up, so you can get down to the 15 psi range.

It is h ard on tires

If 35# does not kill the tires on road you win.
I doubt a tire rated at 80-90# will like it tho!
If you start dumping psi for off road often, Get a set of air compressor drain valves and mount them 180* from the schrader.
This will help balance, and you can dump massive amounts of air quick.
But, you will still need air up gear.

Our tires are supposed to be run around 60-65 per the tag on the door. I run my dually at 70psi just because I would rather run a little higher.

At 80psi each, the tires on my dually are rated to carry 11,000# which is 1000# more than the GVWR Of the whole truck.

I don't remember exactly, but I think at 60 they're rated for around 2000# each.

Running them at 35 is not ideal, but it's not likely to kill the tires if he's running around mostly empty. They'll just wear the edges off.

EDIT: Here you go. 35psi should hold fine. That's about 1700# capacity per tire.

Yes but the handling may suffer from the lower pressure.
