Blackandwhitetoranado- Sorry to hear that your troubles continue. Did you play around with tire pressure? I am running between 30-32 lbs PSI depending on the outside temp and got good results. The other thing I would suggest is make sure they have RFB as close to 10 as possible and ask for the results. Also, are you still on the Bridgestone's? I went through 11 of those tires before I had a full set where the RFB numbers came in at respectable numbers. This will sound dumb, but the last thing I did was reduce the pressure in the air bladders on the seat bolsters (I had mine cranked up because I like the support). That effectively mitigated some of the road feel that was coming up through the cabin as the 22's tend to amplify any road imperfections. Next week if I have some time I am going to switch back to the 20's again to see if there is any difference...I'll let you know what comes of it. Good luck.

DisgustedWithChevyGM- when your vehicle is at the dealer make sure they have applied the Chevy service bulletin "PIT5404B Buffeting Vibration Droan type noise exhaust". This is an exhaust system replacement that eliminated the buffeting issue in my vehicle (the symptom is like having your back window rolled down and getting the rhythmic pulsing that causes fatigue/headache, most pronounced in V4 mode). That was a big improvement for my vehicle while working through the tire/vibration issue. Hopefully the tire pressure adjustment provides some relief as well. Good luck.

Basically the 20" rims solved my vibration issue...I have been posting my experience on a different related thread (that has some additional good info): http://www.gm-trucks.com/forums/topic/194602-2017-tahoe-premier-noise-in-cabin-same-as-others/?view=getnewpost In a nutshell, I ended up calling Bridgestone and talking to their tech support. Turns out that the 35 lb PSI with the 22" tires appears to be overkill based on the GVW of the vehicle (7300 lbs). That, combined with the stiff suspension amplifies road imperfections and is a major contributor to vibration. I ended up swapping back out the 20's for the 22's, and aired down tire pressure to 30 lbs PSI and the truck rides great. Can't speak to long term tire wear at that inflation, but I was ready to give up on the truck based on the vibration, and at 30lbs PSI, it is well within spec for GVW and tire rating. I think the aired down 22" rims gives me the best compromise on overall ride and handling. Not sure why this isn't being communicated through GM's dealer service network as a possible fix or mitigation where vibration is an issue. For anybody experiencing the vibration issues with the bigger rims, I would give this a shot. Good luck and let me know if you see similar result.

Here's the latest for me. Took my buddies 2016 Tahoe LTZ out that is equipped identical to mine, but has no vibration. Test drove it for a while. and the only noticeable difference was that his tires were inflated to 31-32 lbs (versus the 35 lbs recommended on the door frame sticker). Noting that difference, and that my vibration problem went away when I switched to 20" rims with Continental 275/55-20 tires, I decided to contact Bridgestone regarding the Dueler 22" tires and spoke to their technical support. They informed me that at 35 lbs pressure, each Dueler 22" tire supports 2,337 lbs of load, for a total GVW of 9,348 lbs. As the Tahoe LTZ has a GVW of 7,300 lbs (which factors about 1400 lb for fuel, passengers, cargo, etc), he started doing the math regarding load ratings at various tire pressure levels. Bottom line is that the tire has an operating range of about 26-45 lbs of pressure, and if you inflate them to 29 lbs, it has a working load of 2,077 lbs per tire, for a GVW of 8,308 lbs, which is still 1,000 over the GVW of the Tahoe. With that data, I put the 22" rims back on and aired down to 30 lbs of pressure. What a difference in ride quality- huge improvement and no vibration and less chattering over bumps at speeds between 25-45 mph. Took the vehicle out on the highway and got it up to 75-85 mph with smooth ride and no vibration. Got as fast as 93 and no issues. Outside temp was about 45 degrees...running it up to speed on the highway brought tire pressure by 2 lbs (to 32 lbs), but it came down to 30 lbs when cold. Overall, I am pretty happy with the current ride now with the 22" rims as it maintains the handling characteristics with less road feel and chatter. I'm going to play around with the pressure a little more and see how the vehicle behaves, and will report back to the service manager at my dealer.The only investment here was a TPMS relearn tool for about $45 on ebay, which I'll need if I swap back and forth or rotate tires. Overall, I'm pretty happy now as this is the $70k+ truck I thought I was buying. Let me know if anyone else has similar results. Good luck.

True...I now have the option of going either 20 or 22 inch. The 22 rims were checked and they are true to within .001 of an inch, so on the 22" configuration, it vibration appears to be coming from the Bridgestone tire with the stiff sidewall. But to your point, why spend money when it's not a guaranteed fix. At least I have that with the 20s.

Sorry to hear about your issues. As outlined earlier, I had a similar experience w my LTZ, noting I have a buddy with the exact same truck with no issues at all. After 11 Bridgestone tires on the 22's, I ended up buying the 20" rims and Continental tires for short money from the dealer, and the issues for me have gone away. Decided to keep the 22's versus trading back for credit as they will go with the vehicle when I sell or trade in. The other big fix I got was the exhaust system replacement (GM service bulletin) that eliminated the buffeting. On the 22's, my RFB numbers were between 10-13, below the 15 lb spec. Overall, I would still like to get the 22's riding better as they are more responsive (and look better) than the 20" continentals. but at this point I am relieved that the vibrations are gone as it was really frustrating. Got a lot of good info on another thread from SierraMyst: The topic can be found here: http://www.gm-trucks.com/forums/topic/194602-2017-tahoe-premier-noise-in-cabin-same-as-others/?view=getnewpost that you may find useful. SierraMyst thinks that upgrading to Michelin Premier LTX tires will be a big improvement over the Bridgestones, and I'm debating whether to get them for the 20's (on sale at Tire rack for ~$150/tire) or take a shot with the Michelin's on the 22's that are about $100 more per tire. As a side note, my dealer would not replace the Bridgestones with the Michelins as they had them within spec and they were not authorized replacements by GM, but I thought that the 20" replacements were a reasonable compromise. Good luck and let us know how you make out.

I have about 50 miles on the 20's with the Continental CrossContact LX20s, and finally got a chance to get on the highway with them yesterday.Ride is smoother, got the vehicle up to 86 mph, and vibration has appeared to have gone away at all speeds. Want to do some more driving around town to ensure this truly fixes the issue, I did lose some of the handling characteristics of the 22's-better cornering and firmer ride.Can't really comment on MPG or braking as the road conditions outside Boston have been all over the place this week. One day it's zero degrees, and yesterday it was 60 and raining. My experience with the 22 inch Bridgestones was good traction and braking in all conditions, including snow and ice. Would be nice to find a solution with the 22's, but at this point the switch to 20" rims would suggest that the vibration comes from the original tire/wheel combo, noting the dealer did everything they could with the Bridgestones to get RFB numbers below 15 (but couldn't eliminate the problem). Will post again later in the weekend with an update,

Contacted my dealer yesterday. They have a set of factory take-offs- 20" chrome wheels with Continentals (not sure what model), but I assume it's the CrossContact LX20. Going to give them a try for a week and see how they behave, and then make my decision on a tire/wheel combo. Will let you know if they help.

Wrench589- my 2016 Tahoe behaves very similar, but I do not have the 2nd vibration...so I'm thinking that the Bridgestone tires are a major part of the issue as they ride hard and amplify any imperfections in the road, and that seems to trigger the vibrations. I can go over the same stretch of road and get a smooth ride or get the vibration driving at the same speed. What tires are you running? Again, I have the Bridgestone Dueler H/L Alenza 285/45-22 tires, and I am considering either replacing them with the Michelin Premier LTX, or downgrading to 20" rims and getting the Michelin Premier LTX in 275/55 R20. From the different threads I am on it appears that this will have the biggest impact on ride quality.

SierraMyst- Thank you for the comprehensive response! Very helpful. I would like to keep the 22's as they look great. With those, upgrading to the Michelin's would be my choice. But if that won't eliminate the vibration completely, then 20" rims and Michelin's would be the appropriate route to take. The dealer already opened a case with GM, and currently all tires are below 15 for RFB (noting the spec is currently 18- that's why they went through 11 tires). The dealer has been pretty good so far, so maybe I can get them to cover one of these two options, and maybe test the vehicle w 20" rims before going forward. Probably doesn't help that I'm outside Boston and temps are at/near freezing and making the tires stiffer and creating more road imperfections. I guess the other steps would be to ask the dealer to replace the body mounts with the upgraded units. I do not have the roof rack cross members installed, but if that helps I'll buy them and install blocks between them and the roof.My exhaust has already been replaced per the bulletin, so nothing to do there, and the dealer already took vibration readings on the engine and drive train, and those readings were minimal. Can I ask where/how you ended up with all this information? I suspect you may have gone through the same thing. If so, sorry to hear...but thanks for all the data.

All- I am an owner of a 2016 Tahoe LTZ- purchased in October with about 3k miles now. Been experiencing the same buffeting and vibration issues as in the other posts. My LTZ is configured with 22" rims (chrome inserts), Bridgestone Dueler H/L Alenza 285/45-22 tires, tow package with 2 speed transfer case and 3.42 rear axle. Vehicle has been in for multiple diagnostic sessions. First time, dealer recommended road force balance- result was 3 bad tires that were replaced. This helped but did not eliminate the buffeting and vibration in the seat, steering wheel and cabin (most pronounced at 30-40 MPH and in V4 mode). Went back to dealer a second time- they said there is a Chevy service bulletin on the problem (PIT5404B Buffeting Vibration Droan type noise exhaust) and replaced the exhaust/muffler. Drove out of dealer and got on the highway...buffeting 95% gone but still had vibration at various speeds, most pronounced around 60-70MPH. Third trip to dealer, and they did road force balance and vibration meters on engine and drive train. This resulting in identifying 3 more bad tires that were not within spec (engine and drive train was minimal). Fourth time to dealer to get the 3 tires replaced, and they were only able to replace 2 of the 3 because the third tire could not get within spec. Waiting for the one tire as they are always special order. At this point not sure what to do. Vehicle is going on it's 11th tire this week. The 22" wheels ride hard (you feel everything), but should not account for all the vibration. A buddy has the exact same truck with no issues. I have little confidence that the last tire change will fix the issue, and I'm thinking of either getting off the Bridgestones and going with one of the two Michelin choices (Pirelli is another option), or moving down to 20" rims that were on the 2016 Denali I test drove that did not have any of these issues. Love the size, fit and finish of this truck and don't want to dump it at a loss...wondering if anybody else has switched off the Bridgestones or downgraded rims and seen an improved ride. Not what I was banking on for a truck that lists out at over $72k. Any feedback would be appreciated and good luck to everyone in the same boat as me. Update as of 1/4/17- dealer replace last tire...in all the vehicle has had 11 tires now in the 3 months I have owned it..Still experiencing mild vibration, most pronounced at speeds of 35-50 mph (but have not had it at highway speed yet). The vibration is too steady and constant to be feedback from the road surface, but is definitely fatiguing. If anyone has tried tire or wheel swap and eliminated the problem, please let me know. The only other guess I would have is the magnetic ride control. Would be interesting if you could disable the feature and see if the problem persists. From what I have read on other posts, the hypothesis is the combination of magnetic ride control and 22" rims is probably the main contributing factor, but it's unclear if the magnetic ride control can be tested. I also wonder if a road force balance would test magnetic ride control and get it into a situation where it would start to vibrate.
