Chevy Silverado 2500HD ride question

[seekingsummits]

I just picked up a used 2013 3/4ton (previous TV was a 1/2 ton yukon xl denali). This is my first 3/4 ton truck and I fully expected a stiffer ride with this set up vs that of a 1/2 ton truck however when not towing, Im notcing what seems to be a fair bit of rear end hop when driving through town etc. I always like the feedback here and figure there are lots of folks with far more experience than me so just thought I would see if anyone had any thoughts or ideas (other than you should have bought a "-------".

Thanks!

Thx for all the info. Very helpful

I double checked and this truck as the 265/70r17s on it with a 75psi rating on the door sticker. For running down the hwy unloaded would folks really recommend running down to 45psi? Ive not ran LT tires before, only P series and have just never under inflated that much other than for offroading so just curious if folks would really go that low

Think of it this way. Air pressure is holding up the vehicle, not the strength of the tire. So if your half ton then a slightly heavier, on the rear axle, 3/4 ton will be happy with slightly more pressure.......with the ability to air up to 80psi to carry significantly more load.

Yes, go for 45psi. If you do not get a full contact patch on the road, go less. If you have full contact patch, then you could go higher, but only do 5 psi increase or decreases. I run 50 on the rear of my 00 C2500 reg cab, I only have 2400 lbs on the rear empty. No need to run 80 with 6100 lbs of capacity. real rough ride.

Yes, softer ride, full contact with road means less tire spin starting out in slippery conditions.

Most 250/2500 trucks can weigh in the 2800-3200 lb range on the rear tires. Thats only 1400-1600 lbs of weight per tire so yeah nothing wrong with 45 psi in my 2500 Ram/Cummins and LT265/70-17 load E tire when not carrying a load.
The Cummins is heavy so 65 psi works best in the front for my particular truck.

Now on the wifes '16 chevy 1500 4x4 crew cab with P255/70-17" I've found 32-35 psi in the rear gives a better ride plus the tire sits flatter across the tread.
And around 38 psi in the front works best. Now if I'm pulling my 10k car hauler with my blue tractor/7' mower then I use the full 44 psi in all four tires.

You have the best riding truck out there.

I recently drove my parents '16 Chevy 2500 truck and I was surprised how rough it drove. So I asked my dad how much air is in his tires and he said 70 psi. In my truck I run 65-66 psi and I swear that my Super Duty may ride a bit smoother especially on the front end.

Stop drunk posting Troy! Only someone inebriated would think a SFA would give a better ride than an IRS.

Like I said I was surprised... Now I'm sure the mass of a SFA on some washboard gravel road will ride worse, but again the truck road very stiff. Matter of fact it rides rougher than his 05 2WD.

Lower pressure to 40-50 lbs in the rear. WORKS BETTER than new shocks from the half dozen 2500/SW3500 GM trucks I've owned! Even my one personal use dually rode better empty with 40 lbs in the rear vs 80 in all four rears!
IF and THEN if it is not soft enough, try different shocks.

Im notcing what seems to be a fair bit of rear end hop when driving through town etc.

Ride quality and "rear end hop" are two different things entirely. Rear end hop is caused by GM's junk factory shocks not being valved correctly from the factory.

If the OP would have complained about ride quality my answer would be different.

Besides Bilstien shocks, lower your rear tire pressure to about 45 to 50 psi when not towing.

I lower my pressure to 60 PSI and I keep my 60-gallon aux tank full and, if I have time, I keep the main tank fairly full too. That makes a lot of difference. I was going to buy a 1/2 inch steel plate and put it in the bed until it dawned on me that a nice extra fuel tank costs about as much.

I'd much rather have Rancho 9000X adjustable shocks. So much better ride than Bilstiens when truck is unloaded and easily as good as Bilstiens when max loaded.

Ditto.

I have had RS9000x shocks on trucks now, both ruck in my signature and my previous truck, a 2002 2500HD.

I haven't done the shocks, but have lowered the tire pressure. Ride is not bad. Heads up on lowering air pressure, my TPMS alarms at about 50psi so I don't go lower than that usually.

go to your local dealer. they can reprogram the pressure limit warning for low tire pressure limit. I had that done on my 2015.5 Denali.
