Need some help swaying issue with the car

Ok here's the issue.
I just put 2 new tires on the rear. My front tires are pretty much due for new ones they have about 35%tread left.

All of a sudden just after puttung the new rear tires the car is swaying real bad At high speed. It feels like the back is tracking more than the front.

???
40psi all around

Here are the specs
front 235-35.19 30-35% tread
rear 265-30-19 brand new less than 2 miles

I'd try reducing psi to the factory recommendation (32 front, 35 rear for us C32'ers... you're probably the same) and see if the problem goes away. Otherwise, perhaps have your alignment checked?

if you are experiencing a change at higher speeds, it is almost certainly a balancing problem. I think any balancing machine can do staggered wheels. Get your wheels balanced.

Also, Costco is usually more expensive for tires, but they have free balancing/rotation if you buy there, and no hassle dealing with defects. Plus, they only use nitrogen.

thanks but balancing is a vibration issue. The car does not vibrate all all. The cars does not pull or sway at all. Only when at high speeds if you make a swift turn of the wheel the car starts to sway like if it had no swaybars. Went under the car all links look good.??

I am just reminded of how much of a difference on a car's overall handling tires can make. I just put new tires (all the way around) on my car and I am shocked at how good the car rides and tracks.

My guess is the swaying/tracking issue is due to the differential in tread wear. Put new tire on the front and the rear will behave.
