Can anyone give me a idea on tire pressures for a 3500 SRW running stock tires? On my 2001 2500 I was running 50 psi in the fronts and 35 psi in the rears just everyday driving not towing our 5th wheel. I have mine set at that now on the 3500 and the tires appear to be wearing nomal but I only have about 1200 miles on it. Any other suggestions? Thanks

Look on the driver's side door jam. It will tell you

I know mine recommends 60psi front, 45psi rear (unloaded) or 60-70psi rear fully loaded.

I run 70 psi all the way around and I run empty 99% of the time. My stock tires have 43,500 miles on them and they have worn perfectly. I expect to get at least another 20,000 miles out of them....if not more.

I run 65-70 psi all round. Tire wear is perfect.....also better fuel mileage!!!

Thanks guys. I walked out at lunch and looked at the door jam and it says 50 psi front and 45 psi rear with a light load. I have been running 50 in the fronts and they look good. I had the rears to 40 and the outside part of the tread looked like it was not making full contact. In other words it looked like it was over inflated. I guess I will run them up to 45 and not worry to much about it. Thanks again.

Hunter11,

Sorry if this is a little off-topic . . .

I'm looking at a Cruiser 29 with the center kitchen and I have a 3500 SRW as well. How is the ride height of the Cruiser with your 4x4? I know the trailer comes with the axles already flipped. Does it ride pretty level when hooked up? Also, how much bedrail clearance do you have?

Thanks,
Neil

Neil, It rides pretty much level on our truck and I have about 6 to 7 inches of bed height when hooked up. There are a couple of pictures of the trailer hooked up to the truck in my photo album.

Ive been running 50psi all the way around, unless im pulling. Then I up my rears to 75 or so. Tires are wearing well now. When I first got it I was running 75 all around all the time and they were wearing fast due to overinflation. 50 seems to work well to me now.

Hoss

If they're rated for 80 psi then how can 75 psi be over-inflated?? Running 70 psi I've never seen any signs of wear due to over-inflation. In fact, I've never had a set of tires wear as well as these have.

Empty truck in the off towing season I have always ran 40lbs front, 36lbs rear.

My truck came with a book from Dodge on tire presures for different trucks and load. It stated that you needed more 10 more psi for speeds over 65 mph.

I know I'm not a 3500 guy (only 2500) but I'm running 60 all the way around with the BFG rugged trail tires. Tread wear is great. I only tow a light trailer, and some light weight in the back, maybe 1500 lbs max. Even then I leave them at 60. If I load up the bed, and tow, I'll kick the backs up to 70psi. I don't ever get up to my max load, no where near it, so I don't run higher. But 60psi is working great for me. If I hit my max load capacity I may run up to 75, I was actually thinking of running 65 all around, but the fronts are wearing good with 60 in them. Tire pressure is odd, it works different for different people, speeds they run, tires the run, loads, etc.

Per the Tire Inflation Guide in the glove box, the front are set at 55 MT and 65 loaded. The rears are 40 MT and 75 loaded. Of course yo want to adjust the rears and front for the best ride when mt and also best trie wear. The key to getting good tire wear is inflaton and balance and rotation. You need to make sure you get them balanced and rotated every 3 months or 7500 miles whichever comes first

I am not a tire expert, but my understanding of the issue is that over inflation of the rear wheels relative to load lessens the footprint of the tire on the road and effects traction. Thus the recommendation for less in the rear wheels than the front because of the heavy diesel engine. The larger the footprint the better the rear sticks on corners, better braking, etc. So when empty I follow the chart that was in the glove box and run light in the back tires.
