Vibration 80+ MPH

[mrichard02]

I have a vibration at 80+ mph. Tires have been balanced multiple times. I’m convinced it’s not a tire balance issue. It’s a slight entire vehicle shake/vibration. It’s not tie rods or steering while. The entire truck just shakes slightly at 80+. It’s very annoying.

anyone have the same issue? What else could it be ?

My 2022 Tremor does that right around 80mph as well. I've read it could just be the stock tires it came with since it's an off-road style tire, but I've only had it a month so I can't say if that's the case for sure.

Have your tires road force balanced.

Sounds like tires, but could be driveshaft balance. In any event an out of balance that declares itself at high speeds.

2021 Powerboost Lariat with 49k and stock Pirellis. Neglected to properly rotate and towed heavy. Had a good vibration since about 43k miles between 80 and 85 mph, felt in the steering wheel and pedal. New Michelin Defender LTX Platinum tires and now smooth as butter.

So basically bc the stock Dynapro AT2 Hancook tires have weak sidewalls, they add more weights to balance out the weakness?

What were your tires before the Michelin Defender LTX Platinum

No tires are not balanced because of a sidewall weakness

Their balance because there is a heavy point in the tire carcass.

I have a set of the factory Perelli’s, 20 inch
Just over 21K miles
Absolutely zero vibration all the way up to 103

I've never needed road force balancing in the past for any tire i've ever had. So why would I need it now with Dynapro AT2s.

Also other manufactuers don't have road force balancing and they drive smooth as butter.

Road Force Balancing

Dealers don't road force balance beyond 65 mph.

I've worked at a tire store, 65mph on a balancer is darn fast. If the vibration doesn't show up by 60mph, it won't happen at a faster speed.

Went to yet another dealer, and just got my truck back.

Issue was bad tires from the factory. The put a different set of Dynapro AT2s on and no more highway vibration. smooth up to 100mph
