Question about TIRES.... several pages back, someone mentioned they put new Michelin tires on their truck and seemed the vibration issues are gone. Couple questions for you....

 

1. Which exact model and size of Michelin tire?

2. Which vibration issue(s) were you having?

 

I've been reading some reviews on Michelins's Premier LTX SUV/Truck tire and one of the common comments is how quite and smooth the tires are. Makes me wonder if these might be helpful for some of the noise and vibration issues we're all having. Maybe not the shaking in the rear end of the pickups, but some of the other vibration and harshness. I realize it would be kinda sucky if one one particular tire was needed to get a decent ride, but there is no questions tires will make or break a vehicle and so far, the endless parade of Bridgestones, Continentals and Goodyears hasn't done the trick.

That was me and sorry it's a poor example because they are snow tires. Michelin X-Ice 17s and they are 1000 times better than the Firestones, they were out of GM spec. My stock tires are Bridgestone 22s and yes they thump first thing due to flat spots. I'm told its the nature of 22" tires due to way they are made dunno if its BS or not.

 

You have to go back and read all my update posts to get the whole story but I'll abbreviate.

Bought truck it was great

5000 kms slight vibration steering wheel 125 kph

90000 kms vibration worse. installed snow tires dealer put new rear end, now bad vibration 65kph and up. RF tires over and over and over, new drive shaft then another rear end, then shake at 65kph gone. Just shake at 120kph... new Michelins installed which fixed that. Then weather warmed up meaning snow melted and able to drive faster.

Now intermittent vib in steering wheel around 80kph and 123kph with drone sound which is believed to be caused by ECM or something. Im currently driving a V4 it seems. Going into service this week dealer agrees something is wrong. I think really the Mechanics miss my truck.. they haven't seen it in couple weeks.

Let's rephrase this statement a little. "It is the nature of CHEAP 22" tires due to way they are made." Which is as cheap as possible. And GM likes to buy them as cheap as possible.

I was told by a GM mechanic because of the narrow side wall on a 22" the cords or what ever, are layered a different way than say a 18" tire. This is what causes the flat spots that at least the Bridgestone Duelers suffer from for the first 20kms or so of driving and worse in colder temps. I asked if it was a Bridgestone thing and he said all are the same, there's no other way to make a 22" tire. Again I don't know if he was BSing me but I have to say I haven't seen flat spotted tires since the Bias Ply's on an old Fire Rescue truck that sat at the station for weeks at time. My truck sat for a week in November and the vibration from the flat spots was probably bad enough the throw a water bottle out of a console. After 20 or so kms it was gone. It was after that I decided it was time to start looking into vibration problems. At that time everything I knew about vibration was due to tires, tires, and tires. Then I found this forum.

But I will add I was also told, a few years ago the only time they road forced balanced tires was when a tire was out of round or defective, conventional balancing was all that was needed. Now it seems every tire needs to be RF balanced, which kinda points to quality issues or cheap as you say.

Anyone have a vibration once they hit 65mph through the gas pedal? Almost feels like a motorized vibration. Like its happening during a revolution time and time again. Like every half a second you can feel it through gas pedal and sort of here it through the cabin.

Not sure about the flatspotting. Sure, I can understand the concept. And I'm sure tires do it to some degree. But why are these vehicles the only ones that seemed to be bother by it out of the hundreds of other vehicles, GM included? Heck, my 2011 F350 with 20" Michelins sits for weeks at a time, outside, summer or winter, and. Jump in and there is ZERO vibration. First km. Last km. And all the kms in between. So I think the flatspotting is a smoke screen for the real issue, whatever it is.

 

OK , I could see this being an issue if we were talking about a Bugatti Veyron, or a Formula 1 car...can't let it sit around on the tires. But it's a fricken' pickup truck. Like. Said, every other passenger vehicle on e planet isn't so delicate and sensitive to minor flatspots...why is this vehicle platform??

Actually, not such a poor example at all. I put 20" Bridgestone Blizzak winters on mine (from 22" Bridgestone Duelers) and it is remarkably better. The ride is much, much quieter and supple. Most of the road noise and harshness is gone. And the buffeting is all but gone. Made a big difference. Didn't solve it, but certainly made a difference.

 

Since when did winter tires make a vehicle ride smoother and quieter! LOL!!

Most winter tires are made of a softer compound which would smoothen the ride.

I think this speaks to the super sensitivity of our trucks due to the stiff frames. You drive over a pebble and you feel it.

Exactly what I was thinking!

Totally agree.

I guess trying to turn a pickup truck into a sports car has not been a total success.

fix 1 = bought a dodge

fix 2 = bought a toyota

fix 3 = bought a Ford

 

Personally, I had great success with a stupid $18 clamp. My truck is vibration free.

If you go back to around page 550 and read forward you can find all this info.

 

Frenchsquared,

 

I can't remember at this moment, I know you have the clamps behind the u-bolts about 8" you said. Have you tried them in front like some others? Just curious if you had what were your results? I had mine 5" in front of the block and didn't like it all that much around town, might try the rear, but wanted to hear the difference if you had done both. Thanks!

I have not tried the front. Mine is softer around town with them.

I wonder if the shorter wheel base of the Regular Cab has an impact.

Not too sure, I have a crew cab short bed. I torqued my u-bolts to 110 ft/lbs before I installed the clamps as well which might describe why mine didn't ride as well with the clamps, and I also have Bilstein 5100's in the rear so I am not exactly comparing apples to apples. I took the clamps off and its quite a bit smoother, might try the rear at some point.

Traded my 14 for a 16 this past Saturday. Within 5 miles after leaving the dealership my wife looked at me and stated "why is it shaking" I said I don't know. Put 100 mile on it between Saturday and Sunday. Could definitely feel it at speeds around 75 mph. Called dealer first thing Monday and took it in at 2:00. They did the normal RFB and stated to try it. same thing and right back to dealership. My salesman and I took 2 others for a ride and neither was completely smooth. After reading all these posts yesterday I went straight to Advance and bought clamps and put them on. Hopefully tonight I will test this fix.

My fault as I didn't drive the vehicle before purchase. Honestly, brand new didn't think is was necessary. No doubt I would not have purchased it.

So now Im at the mercy of the clamps or see if a fix is ever found. How disappointing.

Im lifted so my u-blots were crushed on as tight as possible.

    • Update for anyone following:    Installed everything as shown in diagram. Opted for 8 AWG from Battery Positive to a 50A resettable inline breaker. 8 AWG is tied into to 2x 12 AWG wires feeding a 6 way fuse bus in parallel (manufacturer’s design of what I purchased).    4 of the 6 fuses available for circuits are tied to terminal 30 of each relay. I tied a jumper from one of my spare circuits off the bus to terminal 86 of each relay. The trigger, terminal 85, was pulled from my interior by way of T-Taps from the X61A-X5 pins 10, 11, 17 and 23. This was the hardest part of the job. Even with the X61A unbolted and the X5 removed - there was VERY little wiggle room.  I added back up lights that I want to come on with my cargo lamp - but when I would check continuity between S48A-X1 pin 18 to its respective landing point on the X61A-X5 it triggers the factory relay… Instead I opted for a add-a-fuse on the passenger interior fuse panel (fuse location 10 - cargo lamp) and ran it through the boot on the driver side to my load. Did this to avoid introducing any electrical gremlins.   Note: Please check for continuity between the S48A-X1 and the X61A-X5. In my case wire colours were not the same as other’s who have posted. To do a continuity check you need a Multimeter. Completely disassemble the S48A-X1 and remove the brown face plate off the X61A-X5 by way of a flat head screwdriver - this was the only way I could get any results.   The outputs, terminal 87 of the relays, were fed into a junction box and landed at Individual studs and were labelled Aux 1-4.    At this point, all you need to do is run wire to your loads and bring them to ground. I created a negative bus in the engine bay, all my negatives land here.    For anyone having issues with all of your new aux switch lights coming on with the press of one - I noticed this only to be an issue when the battery wasn’t hooked up to my relays? No idea why, but it was quickly corrected by having my system buttoned up and functional.     
    • Well I ordered the Autel ts508, and it won't work on my truck I tried all the 2023 and everything it just says vehicle not supported lol   I'm able to send this unit back, so I'm going to do that, then I'll just stop into a some tire shops and if none of them are able to do it, I guess ill have to spend a bunch of money to get a good scanner..... Thanks GM lol
    • Don't need the air tube but that's how everyone sells them. Most places won't remove that one piece and sell it alone. No money to be made. Hoping someone swapped theirs out for a CAI and no longer wants it. Not asking anyone to give it away. Offering to buy it but I don't need the tube. It's held on by a hex head screw and nut. Been all over eBay. 
    • Wait, you guys are changing your oil???
    • If you need that mount looking piece.  You need the air tube.       Cheapest one I see on eBay - 2007-2014 GM Silverado 1500 Air Cleaner Outlet Duct Assembly 5.3L OEM 15901934 | eBay     Same price but free shipping - 2009-2014 CADILLAC ESCALADE 6.2L AIR CLEANER OUTLET DUCT ASSEMBLY 15901934 OEM | eBay
