Any of you have 275/60R20 tires or larger? If so, what brand? Improvements to ride quality? I've been all over this forum and a couple others. Mostly curious.

Yes. Toyo A/T close to that size for the first 55K miles, BFG A/T KO2 for 14K miles since. Smooth all the way. Fuel 20 inch wheels since day one.

 

I've driven about 20 Silverados and Sierras, 14-16 model years, and all have been smooth except for one 16 Silverado crew with 5.5 box. Currently have my 14 Sierra crew 6.5 box and 16 Silverado crew 6.5 box. They're both 4x4. The Sierra is non-Z71 with aftermarket wheels and tires, the Silverado is a stock Z71. Sierra has 69K miles, Silverado 2,500. Both smooth. Both 5.3 6-speed. Both averaging about 20mpg overall.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Could a few of you give more input on how much vibration you're experiencing? I started out with my center console shaking to the point where water was splashing around at highway speeds and my passenger headlight flickering. After 2 visits to the dealership and having 2 tires replaced and all road force balanced I'm only experiencing minor vibration in the steering wheel. It's it even worth it to make it absolutely smooth? How sensitive are these trucks to road imperfections? I feel like I might be being too picky. I mean it is a truck after all, not a sports car?

According to them, GM does not warrant tire balance. They people at the dealer aren't being assholes about it but I will drop it right back off if it isn't fixed.

Bullsh*t, Ive had my tires balanced 3 times and 10 different replacement tires (not including the originals) and never paid them a dime.

 

Keep the receipt because it will feel great for a few days and slowly return. Get your money back when it does!

Don't pay them to begin with, ask them to let you test it fora week or 2 then if its fixed maybe pay them.... or dispute it on a credit card haha

 

Yeah I believe GM covers the tires, from having to replace them or to rebalance them, up to 12k. My dealer ate the cost of rebalance at 34k, they are awesome

exactly

 

I don't see how they can charge you. I just had two replaced and all 4 road force balanced. Plus the front 2 re-road force balanced after I still was experiencing vibration. I left the dealership today and I'd say it's 98% fixed. I maybe just looking for it so much now that I don't know what fixed even means anymore. I swear I'm paranoid about the issue now, especially after reading this thread lol

I think everyone is paranoid about it haha

These trucks have proven to be extremely sensitive to everything

I'm with you here. They've balanced these this down from an obvious steering wheel shave to minor trembling on the steering wheel.

 

If I hold the steering wheel with both hands, it pretty much reduces the trembling to an acceptable level. So much that I think the tech would think I'm being OCD.

 

There moments when this changes, I can have a cold morning and it drives great. And I can have a really hot afternoon and it will tremble.

 

Considering how much has the vibration has gone down since the road force, and how the trembling varies with temperature, I'm really tempted to say it's the tires.

 

Even though I want BFG KO2s, I'm strongly considering just switching the tires out to Michelin's LTXs. It'll have to be better than it is, maybe even squash the problem.

Back again, I do mostly highway driving.

 

I am looking for someone with some mechanical advice on the vibrations that I experience.

 

The vibration moves around. Seat uphill and steering wheel downhill. Comes and goes. Sweeping highway turns seems to be aggravate it more than other things.

 

I would say tires but I have had them balanced and RFB countless times.

 

Any mechanics have an idea what would cause the issue in the turns? That is where I want to start.

I got call from the dealer. They are saying 3/4 tires are bad. One is a 3. The two are just above 20 and one is 40. Unfortunately I did not buy my tires at the dealership. So I called the place I bought them and they are saying that the road force balancing is not a definitive answer that a tire is defective. So now I have prove to them that something is bad with their tire.

I have feeling eve

You took the words right out of my mouth. Two hands on the wheel and it drives really well. Driving with 1 hand, I'm about to lose my mind with the vibration even though it's minuscule. I wish I could drop the coin to try out new tires but it's not in my budget at the moment. Also I feel like I vibes more when in AFM (V4). I just went on a 30 minute drive and it feels like I'm getting steering wheel vibration at most speeds. If you buy new tires please post if it helped or didnt. I think we have the exact same issue.

Well my vibration is completely gone. Was tires of the dealership excuse. So I decided to try a few things myself. I started with swapping CV axles with new ones from the parts store. No change so I returned them. Then I replaced the drivers side hub assembly(wheel bearing) And all I have to say is POOF it's gone. Rides smoother then new. 8c5c6e32e09155dc17a492ca515ccdf8.jpgd8ad7df6819b239b4b3752e473a97836.jpg

I own a schizophrenic 2015 Silverado 1500 4x4 Z71 Crew Cab. Bought new in October, 2015. First 300 miles I thought I was driving a Cadillac. Then hit 76 mph on the interstate and got the shakes, bad. At 1600 miles dealer replaced 2 tires and 2 shocks, RFBd the wheels/tires and things got much better, in particular the 75-80 mph highway vibe. Now have 9000 miles and intermittent vibrations/shakes/jiggles anywhere, anytime/ any speed / any road surface. And sometimes the gear shifts feel like an old first generation auto transmission from 50 years ago. Went to dealer, drove a 2016,and 2017. Unfortunately I feel the same underlying shimmy/jiggle at any speed, just not as severe . Cannot believe GM gets away with selling this crap. I'm done. Life is too short to dance with ugly women or drive a POS truck . And we taxpayers bailed these charlatans out. Ughh.

Where were you getting vibrations and what did it feel like?

I wear crocs when I work on vehicles sometimes, unless it's something like a transmission or rear end or something. They're like clouds for your feet #noshame

There actually are standards for RFB tires. 40 is way over, 20... depends on where withing 20 it is. If i remember right 23 or 25 is the standard high. 3 is very good, and a very stiff sidewall

      It's possible the two trucks are using different body control modules which is why yours works and the OP's doesn't.   So much in these newer vehicles depends on model/trim configurations, production date. They don't all use the same modules like back in the day.

      I forgot to answer the question as per what market mine is set to and yes I finally found that area on mine and yes its also set to America.   So here's something I realized as I wasn't looking at that part in the Sierra section until now, your right that what I see here as choice 3 under Sierra which says 07/2023-06/2026 ( 433 MHz 13542523 ) it has no choice 5 for tire pressure selection. Where as it does under the Chev choice. However I kept going down the list within the Sierra and I am really wondering if choice 9 will work for your truck as it has the same model number and hertz sensor as my truck. I would say try that choice first, if that doesn't work then jump over to the Chev section and again choose that same model and hertz choice as for some reason the Chev section gives the choice 5 of tire type/pressure selection for going back a number of years. Could very well be an Autel thing that they just didn't get the updates all done properly under Sierra but anyway first try that selection 9 I suggested under Sierra and then go from there.

      Anyone have a spare?

      Looking for this piece that holds the hose clamp in place. I have the hose clamp just not that other piece. Dealers and wrecking yards in my area will not sell just that piece. They want you to buy the whole air tube $100 +/- to get that $5 part.  that piece isn't molded to the air tube as I looked at my friends truck. It's held on by a screw and nut. I'm trying to put the OEM parts on the truck as the previous owner butchered things up installing an aftermarket CAI. It really looked homemade. 🤣 Thanks

      Ok I missed that part that yours is a GM. The strange part is that the choice for year ranges and within the year of 2026 is different on the Sierra then on the Chev for some reason as I am looking at my tool at the Sierra choices. Now I am guessing you see as to your sensor part number as it may be different on your truck for some reason and a call to GM should get you the part model number of the sensors you should have as well as which MHz your sensors are. I know mine are the ones as per what I listed but there are other choices in the Autel and got me wondering if by some chance they put different ones in your truck. Having said that, did you try using each of the choices starting from No 1 and going on down the list, not sure if that would mean shutting off the engine each time and resetting the tool and going at it again each time. Also I thought of something else which may sound retarded but if there was some stupid chance that the chev choice would work. The reason I say that is that the Sierra is showing a range up to 06/2026 for the various choices of sensors it could be where as the Chev has one choice that has that 12/2026. By the way it is possible to not run the truck and you may know that as per not pressing the brake but pressing and holding the start button for a few seconds and it lights up the dash ( its called service mode ) but that sucks battery power and if it were me doing it that way I would be throwing on a decent sized battery charger before doing it that way as killing your battery won't make you happy at me at all !.    Like I say, just a thought to try the Chev choices if you have already exhausted the Sierra choices but first it would be nice to know for sure what exact sensor model and hertz your truck uses as I assume only those choices that mention the sensor would work unless a choice that does not mention the sensor model would somehow work. Its frustrating when one is trying to use tools like this without the experience of the tool and the vehicle, as I am sure dealer techs themselves struggle with it when starting out or a new model year comes along that is slightly different.

      I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?
