Stirring wheel shake then stops

Hey, so I got new tires. Ridge grapplers 265-75-16

bad shake when they first put them on over 55

got rebalanced

seemed ok, today drove it and it did it again then after a few minutes stopped.

what could be cashing this?

 

If they are still causing your truck to shimmy/shake, then they still aren't balanced. Have them re-re-balanced. You may also have defective tires.

 

Wonder what would cause it to shake some today, then stop after driving a few minutes

 

What tire pressure?

 

35 cold
37 driving

It’s riding ok right now which is weird

it’s happened today right when I first started driving and then seemed to “settle” in

 

Sounds like they flat spotted, from sitting.

 

What’s that?

 

Is that normal

they are brand new

 

Tires were the only thing changed?

 

Some tires, not all will flat spot a bit when sitting a bit. Either from sitting on hot surface, or long time. Also poor quality tires will do it also (which your are not) But no experience with ridge grapples, on terra grappler. Have had ma y set, with no problems.

 

Yes

 

They were sitting on grass :/

 

Ridge Grappler's don't typically flat spot. I've had three sets and my SIL at least 5 sets on different vehicles. They are great tires. I'd take them back to the shop if it happens again.

 

The SuperSwamper Radials I ran on my Explorer would flat spot over night regardless of temperature.... not the best daily driver tire in hindsight but awesome offroad!

 

I get a bit of flat-spotting on my K02s but only if they sit for several days.

 

Make sure the shop that mounted the tires has the proper adapter for Toyota wheels when they balance them. I had an issue like this on my Gen 1 a while back and finally had the dealer balance them and they were smooth like new.

 

It was a ford place. My mom got a discount there.

wondwe if that’s the issue

maybe I should take it to discount tire?

 

Rotors ?

 

Are these your first LT tires?
How old are your shocks?

 

I say tires are flat spotting and after you go a few miles they return to round. Very common in today's tires. My factory Toyos do that every morning on a gravel driveway. Usually notice it more on a concrete or pavement but that's what they are using in belt material today in tires.
