Just wanted to give everyone here a heads up as to what we have been experiencing at the 4x4 shop I work for in my spare time.

The issue is with Factory Aluminum wheels, with the clear coat type of coating (not sure of the proper name).

 

We have had several customers over the past few months calling and bringing their trucks in due to low tire pressures. Their tires have been leaking air over a few days from 40psi, all the way down to 25psi in a matter of 2 days.

 

It was discovered that the tires were leaking around the bead and it is caused by the blistering of the clear coating on the factory wheels. This is being fixed by removing the tire from the wheel, and sanding the area where the clear coat has started blistering and is affecting the seal of the tire to the wheel. He is also applying some sort of 'special' bead sealer that is ordered through GM. Not sure which brand it is because it comes in an unlabeled container but GM said they are well aware of the issue and it should not happen with the current model of trucks. They claim that the 2014-2016 aluminum wheels use a different coating than what has been used in the past.

 

If you have a GMT-900 you may experience this issue at some point in time. My 2008 is one of the vehicles experiencing air pressure loss on three of the four aluminum wheels. After it was sanded down and had the coating applied, it's been holding air as it should.

 

If anybody here is having an issue where you are noticing a loss in air pressure, this is probably a good place to start looking to find the problem.

      on-wheel cellphone control: 2026 1500 WT (2.7L 4WD std cab)

      By bwiese · Posted

      I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
