I need help with finding why my truck is riding rough.

Last week I got brand new tires and wheels put on. Every since I got them put on it’s been riding very rough, the steering wheel shakes and the whole truck bounces. They said my wheels are good. Could it be my leveling kit because I still have the stock shocks?

 

What new tire did you buy?
Did they road force balance the tires?

 

I got General Grabber and yes they did a road force balance.

 

Just out of curiosity, what is the weight of the new tire/wheel combo compared to the old ones? Heavier tire/wheel with stock shock is a non starter.

As I've said before folks take a completely stock suspension that's been engineered by pretty smart folks, then start changing things and wonder why the ride and handling change.

 

Depends on how aggressive the tread is will also affect how it rides

 

The tire/wheel combo is definitely heavier. Do you recommend getting new suspension?

 

The tread is aggressive, they are mud terrain‘s

 

When the suspension was designed they took into consideration the stock tire/wheel weight. Now that you've changed that you'll need a different shock. Talk to several suspension shops and find out what they recommend.

 

Unless its shaking excessively I'd say its that vs anything wrong.

 

They are likely load range E which is gonna ride noticeably different. I’ve also seen places inflate them to 50 psi, when really you want them closer to 30

 

if the only thing U changed were the tyre................

Ur truck then rides ruff !!

must be the tyres

 

The steering wheel shake is likely caused by a tire(s) being out of balance. The rough ride is most likely caused by over inflated tires.

EDIT: note also that excessive snow, ice, and/or mud in the wheel can cause the wheel to be out of balance and cause the same steering wheel shake.

 

I’m very skeptical the OP needs a new shock absorber for his new tires. I would check wheel balance and tire pressure first.

 

Tire shops usually over inflate the tires. It's dumb, but maybe it helps when balancing??

Definitely check your tire pressure. 30-35psi should be about right for street driving.

Also, "recovery" probably isn't the best place for this thread, lol...

 

With E rated tires 30-35 PSI is about right on a Tacoma. Those tires are normally used on 3/4 ton trucks where 50 PSI is minimum. Tire stores see E rated tires and put 50-60 PSI in them.

And if they are a taller, wider tire with a more aggressive tread they will ride rougher regardless. There is no free lunch, if you run tractor tires on a truck don't complain when it rides like a tractor.

 

My dad would always complain about the tire shop setting the tires (not E rated) on his Sequoia to something like 50+ psi.
