Fish-tailing on grooved cement

[Buickracer455]

Has anyone experienced fishtailing on grooved cement like this? It feels like driving on Bias ply tires. 

 

it happens at speeds as low as 40 and as high as 80. 

 

I am concerned with towing a boat. Trailer whip is no fun. 

 

Per the dealer, GM wont do anything, Truck  is '19 Silverado 1500

 

Tires are currently Michelin Primacy LTX 265/65R18

 

Dealer talked to Michelin and they are willing to change them out to Energy saver A/S. I havent decided yet/ 

 

Has anyone experienced this and found a fix???

Are you towing when this is happening or accelerating.. just driving and the back goes sideways.. doesn’t seem likely for that to happen.. maybe bad tires if it is. Rotate them to see if it’s still happening. Maybe alignment. You didn’t provide enough information though for anyone to understand what’s happening.

not while towing, steady speed, on cruise control.

 

It is a back and forth fishtailing, not kicking out to one side.

That’s usually a tire issue. I haven’t noticed it at all. Do you an aggressive tread tire on the truck?

agree, Service manager said it is tires, but what tire fixes it. 

Dealer is limited on what they can do.

original tire is this

new proposed tire is this tread

i wonder if the new tire has a larger or smaller contact patch given different groove pattern.

keep the LTX,but see if they will exchange them for new one for testing?

That's not fishtailing, that is tramlining. It is a unique combination to the road, tires and vehicle. Wider tires tend to do it worse or very skinny tires (ie Motorcycle tires). Nothing to be worried about, if they will swap go ahead and try a new set but I bet it won't correct it, just a unique charateristic of that particular stretch of road.

my concern is what is it going to do when pulling a trailer. 

 

i will know more once the weather breaks.

i am thinking the new tire will be better having only 4 grooves around the circumference, less edges to grab and less cuts on the tread in general.
