Shake @ 50+ MPH

I own a 2016 Toyota Tacoma SR5 4x4 3.5L V-6 Automatic with 30,000 miles on it.
I have recently replaced the 245/75Rx16 tires to a set of 265/70Rx16 General Grabber ATx W/L tires.
Ever since I replaced the tires, I have a shake in the vehicle @ 50+ MPH.
I have had the tires rebalanced and checked for out of roundness.
My husband has also greased all the u-joints on the vehicle.
What else should I be looking for to eliminate the shake?
Thank you.

 

I've heard General Grabbers can be tough to balance, but it's anecdotal.

I have a shake around 45-65 mph on my 2021 SR5 stock tires that I'm hoping goes away when I get a new set of Cooper Discoverer AT3's and a full balancing. Toyota dealer pretty much ignored me when I complained about it.

 

A few years back my tire shop got a new Coats balancer. It did not have the correct arbors to hold these aluminum Tacoma wheels.

 

I normally wouldn't say to jump the gun, but I had nightmare issues with balancing a different brand of tires a couple years ago, so firstly, I'd recommend contacting whoever you bought the tires from, filling them in on your issues and see what they advise. If its a reputable seller, they'll recommend a specific shop for install/balance. Even if its inconvenient, make a visit to them and keep paperwork/receipts. If issue persists, keep your case open with the seller and go from there.

FWIW, I went through way too many tires mounted and balanced at multiple shops, only to find one recommended by the seller that could road force balance them, and after about 9-11 tires (I forget), they finally got a set of 3 tires that weren't deemed out of round by their recommended shop. Call me unlucky I guess, but at that point, I switched tire brands completely and all issues resolved. I DON'T think this is your case, but save yourself the headache and just use the shop they recommend so the seller can assume responsibility and warranty/replace them if needed, even if you know your guy can do it better.

Edit: shameless plug, @Discount Tire is my new go to after that horrible fiasco.

2nd Edit: I wouldn't chase other issues just yet. If your vibes didn't start until the exact day you changed tires, its most definitely your tires, even if they "balanced within spec" whatever that means. Just keep composure and professionalism with seller, and things will work out. Good luck!

 

Discount tire also fixed my out of balance tires.

 

I say rebalance again. If it wasn't there before the tires then I say it the tires.

 

Road force balancing may solve your issue.

 

This.

My local Toyota dealer was the only place that could get my wildpeaks to balance.

I know most dealers have a special adapter for the large center bore of our wheels.
