Expectations too high for ATs? Vibration at 60-65.

I haven’t ran an aggressive tire since my Tacoma back in 2015 (Duratracs), but never had much in the way of vibration due to balancing (they had road noise, that’s for sure, but no balancing issues). My Trxus M/T’s on my old Tacoma were balancing nightmares. Anyways, I just put on Coopet AT3’s after having driven the first 30k on my Dueler H/Ts. I knew the ride was going to be a little more rough going to a more agressive tread and a Load Range E from a P rated tire.

The AT3’s are actually quite quiet and very smooth. Until I hit aroun 60-65mph. The steering wheel vibrates (not violently), but it’s noticeable and a little annoying. Obviously it’s a balancing issue, but my question is this the expectation with tires like this, or should I try to get them rebalanced? I don’t believe the shop I had it done at is going to do them over free of charge, and I don’t think after this, I really want to take it back to them.

Then again, maybe this isn’t out of the oridinary? I just figured that with a mild AT like the AT3, it should ride relatively smooth.

Thoughts?

 

I’ve got nitto ridge grapplers on my tundy and have had it to 80 with no vibration what so ever. I’d try having them road force balanced at a reputable shop

 

I run the AT3 as well, I have to have the wheels/tires dynamic road forced balanced.

 

I’ve had wildpeaks at3 and open country atII’s an neither vibrate even up to 90mph. Take it back to the shop.

 

Take it back to the shop.

 

Initially I had balancing issues with brand new Ko2's. I was pissed. I took it back to the Discount Tire that I had purchased from 5 times !
My wife looked at me and said maybe there machine is fucked up. Took it to another Discount tire location and Bingo ! smooth and no shake at any speed ! I then took her to a movie and dinner...

 

That's what I figured. They don't use a road force balancer at the shop I used so I doubt they will make it better the second time. I suppose I will call around and find someone who does.

 

I just placed my order for Cooper AT3 today, and will be installed on Saturday. I initially was going with LT305/55r20 (E rated), but the owner of the shop that I purchased them through and will have them installed by talked be out of 10ply E rated. Going with 275/60r20 instead, as he told me they would provide a more quiet and smoother ride than the E’s.

 

I am thinking about buying the same for my tundra... what was your otd price on those with the rebates?

 

I was quoted at $190 a piece, but I will know the final price in a few hours when it’s done.

 

$198.98 each, no rebates

 

Thanks. It's actually intermittent. Some days it vibrates a bit at 60-63mph, other days it's just fine. Odd.

 

I had balancing nightmares w AT's as well. Don't assume your DT shop has a road force balancer, not all do, more importantly don't assume the tech knows how to use it anyway I finally took it to an offroad shop who had a road force balancer and they got closer. Still had minor vibrations at 60-70. Took off the wheels, cleaned all the surfaces to shiny metal and this finally fixed my issues. My wheels and hub surfaces had just enough grime on them to cause the vibration. Apparently the techs ignore this grime and fight with the balancing instead??
