2016 Sierra 2500 HD tire pressure

[newdude]

Is TPMS still optional or not required on 3500HD trucks? SRW and DRW. It used to be on GMT900 platform.

 

The GMT-900 3500 SRW trucks were 9900 GVWR. DRW trucks didn't have it as they are over 10,000 GVWR. Federal TPMS standards are anything 10,000 GVWR or under must have the TPMS system. 2011+up, all the 3500HD trucks are 10,000 GVWR or over. Any 3500HD that is 10,000 GVWR can get TPMS, but those trucks are hard to find, as the majority are 10,700 or over.

Some 3500's can have TPMS, if equipped with the 10,000 lb GVWR option.

 

From 2016 Order guide or 3500:

 

RPO code UJM Tire Pressure Monitoring System (does not apply to spare tire)

1 - Included and only available with (C7A) 10,000 lb. (4536 kg) GVWR.

And RPO code C7A GVWR, 10,000 lbs. (4536 kg) with single rear wheels

1 - Requires *35743, C35943, *35953 or *35903 models and (L96) Vortec 6.0L V8 SFI engine or (LC8) 6.0L V8 SFI Gaseous engine. Requires (AY0) single-stage air bags.

If, for example, a 35743 (which is 3500, 6.5ft box, crewcab) is ordered with C7G which is 10,500 GVWR it would not have TPMS, but ordered with C7A, it would be 10,000 GVWR and it would have TPMS.

If it is a dually, it will not have TPMS.

I run mine at 15psi up front and 10psi in the rear, 15 up front so I don't roll it off the rim. The locking rear end and down hill speed control really help here. The speed control acts really weird but it really slows you down. Going down steep dunes was a perfect test. This is Silver Lake Sand Dunes in MI.

Thank you to the OP and others.

 

I have lowered the pressure in my tires and it is really helping with the ride. I waited until the dealer fixed the airbag recall because I knew that if I lowered the pressure they would just air them back up again. Sure enough they put even more air in while it was in there. So right after I picked it up, we lowered the pressures in all of the tires. What a difference it made.

I just threw on a set of 275/70R18 BFG AT KO2's and got rid of the stock 265/70R18 Michelin LTX AT2's. Wow, what a difference. I am running the same 55 PSI in these as I did the stock tires, but the ride is simply outstanding compared to the Michelins (kind of hard to imagine Michelin and BFG are the same company), and the handling on the gravel roads I drive regularly is a world of difference. It is much more sure footed on the bumpy, rutted, loose gravel roads. Nary a slip. And highway ride is darn near as good as a 1500. Not nearly the log wagon feel riding down the road, and the BFG's are not noisy either. Cornering stability is much better also. Wish I would have thrown these on sooner. Like I have a totally different pickup. This winter will be different, I can tell already. I haven't really had them out in the fields yet, since they just went on the pickup Monday, but am confident they will do the job far and away better than the Michelin's did. As soon as farm crops out, I will take the pickup out and climb a few terraces and throw some mud and get a better idea how they are.

 

The speedometer was a tad off with the stock tires. About 1 mph faster than actual speed. These one size up BFG's now have the speedometer dead on.

The Thread looks much more aggressive ... but you say on the highway they feel smooth (?) Are they LT's ?

[Cowpie]

Yes, that is them, LT275/70R18. For me, well worth the cost. Very little road noise on the highway and great ride. Granted, I am running them like I did the previous Michelins.. at around 55 PSI empty and light loaded. Only would air them up for a heavy load. Just feels like I have a totally new and improved pickup compared to the Michelins.

 

The 275/R7018's are the next size up from the stock Michelin 265/70R18's that were on it. So there is a little wider footprint and about 1/2" larger diameter.
