6oz's of weights on a new tire/rim?

allenwhite88 · February 11, 2017

Bought my truck in to the dealer, Had the vibration problems, had to wait about 2 months for my dealer to get a pico scope in. They had my truck a few days, when I got it back it still vibrates as if they didn't do anything to it. However they put 6 oz's of weights on my rf tire, and there is 0 weights on my lf.

Yes, there is 12 1/2oz weights on one tire, talk to a friend and he said thats rediculous that theres that many weights on that size tire. He suggests that the rim/tire might be a problem still or theres another problem they are trying to cover up, keep in mind the dealer says this is normal to have a strip of weights a foot long on my brand new truck. What's up with my truck? no one at the dealer can figure out why it's vibing, I told them i've researched it and now they keep me in the dark. Glad I paid cash for a steel dildo.

By the way guys, they changed both front tires

Sounds like the regular tire balance guy was out sick that day or had laid out drunk (luck of the draw) just take it back and they will fix it LOL

I did, it ended in a shouting match of me being told i have no idea what a tire balance is, thanks for the reassurement

What wheels and tires? Takes more to balance an 80lb combo.

just stock 18s and "factory certified" wranglers

just stock 18s and "factory certified" wranglers

When the dealer had my 15 for a month, they couldn't find a better balance than my stock wheels on my big, chunky Hankook iPike snow tires. The GM tsb allows for them to pull sets off lot trucks and my dealer admitted that they were all in worse shape than the snow tires. At first they blamed a set of aftermarket wheels I had no until I sold those and put the stockers back on. They couldn't argue about snow tires as those were the best ride obtainable.

I selling my Wranglers with 5K miles on them and getting Michelins @ $1300 from Tire Discounters. The vibration was still there. After showing the TD manager the GM vibration diagnosis buletin, he personally spent a few hours replacing two defective (brand new) michelin tires and getting the road force to under 9lbs. It road like it should on the highway, the vibrations are gone.

Long story short,, take it somewhere that has the newest hunter balancer with the latest updates, have them turn off smart weight which saves the amount of weight but on the wheel, but can cause problems with RFB. Have a good road force balance done. They may find that you have defective tires... Which I honestly believe mine were caused by the jack-hammer front shocks these things come with from the factory. My two failed tires were both fronts.

They have replaced my two fronts with brand new wranglers(same as I had) its the same ride, they said my other two tires were defective. However, They had rotated my tires a month before and so that means my rear tires were defective? but it shook and vibed the whole time ive had the truck, I just don't understand why my brand new rim/tire combo needs 6oz's of weights to balance a tire when it never stopped the vibe, I had a 2nd opinion and they same my rim must be bent, or there is something else they realized they can try to cover up by doing this. They said they looked at my driveshaft and it's not that, they literally said there is nothing wrong with my truck even after having their foreman ride with me and admit to me(later to deny he felt the vibration when I was with his boss)

So the next step is I have to go to another dealer, my neighbor told me to buy a box and lemons and park my truck outside their lot and hold a sign that they cant fix my lemon, he says people do that all the time and then they start helping them more.

A road force balance will show if it is within "spec" which I believe is around 18lbs. The two bad tires I had would never be corrected with just weights. The tire was too far out of round.

I have the printout of my specs, supposedly they were very far off annd now theyre in spec, my issue is they did all this work, threw weights on my rims to balance it, and nothing new. All I have to show is a ft long strip of 1/2oz weights leading to 6oz on brand new rim/tire, while all my other rims have less than 1oz

The Wranglers are a POS tire, I hate them. That is the only complaint I have about my truck (right now). Don't forget, GM puts on the cheapest tires they can get.

I have owned 2 of the new style trucks now, both crew cab 4x4 with the 6.2l. Both trucks had the OEM "All Terrain" tires removed at purchase and replaced with Nitto Terra Grappler at Discount Tire, both times I had them road force balance the tires. I put 30k miles on the 2014 truck and other than rotating the tires never had to rebalance those tires again. Same for the almost 10k miles on my 2016, all I have done is rotate them. No vibration issues at all.

If it was me I would push for a couple of things. Have the wheels and tires stripped down. Have the wheels balanced out on their own with no TPMS sensors in them and see if they zero out. Then put the TPMS in them and have the shop mount the tires with the heavy spot of the tire opposite of the TPMS sensor (there is usually a dot on the bead area of the tire from the manufacture indicating the heaviest spot of the tire, it is to be mounted across from the valve stem to offset the valve stem weight).

Then RF balance the setup, if the wheel/tire is out of spec then the tires are bad, the dealer should replace them. If the dealer can get the tires with in spec but the vibration is still there then they are supposed to go thru the rest the of the vibration analysis process per the GM TSB process.

They have gotten the tires in spec(supposedly) but it is still vibrating/shaking. So did they maybe keep doing the rest of the process and couldnt figure it out so they gave it back to me? or did they not drive the truck after they did replace my two fronts?

they literally said to me they cant do anything because they don't feel a vibration, however I know they do and they did while driving with me that they wont admit now. Should I say I don't want wranglers?

GM has a very specific vibration analysis process that uses a pico scope that attaches to the truck, they then drive the truck around and the hertz the scope measures tells the engineer where the vibration is coming from. There is only a couple of places, all easily ruled out. Engine/transmission, driveshaft, rear-end, and the tires. If It was me I would speak with the service manager and have them open a case with the GM TAC center to get the equipment sent out so they can trace it down.

It has been mostly narrowed down to bad drive shafts, rear-ends or tires. I am surprised your dealer is struggling, but then again some techs just don't want to invest the time into the process.

I personally feel like they knew about this and had problems with my truck before. I bought it with 500 miles. I've mentioned i'd like them to look at the drive shaft and they throw it off and say we did its not that, I mentioned the rear end and they said its not that either, so when i brought up why is it still doing it when you changed the two fronts they say theres nothing wrong with the truck anymore, and they cant legally drive over 72 so thats where it ends. god forbid i want to drive my truck 80 on a hwy. So, that's where their scapegoat is with me, "they cant drive over 72 to feel the vibration"

So can't you drive and just have them ride along with you.

Also if you believe it's the wheel out of spec, take the tire off and put just the wheel on the balance machine to eliminate that.
