If there was no problem prior to the tires, and the only thing changed was the tires, then it must be the tires. Bad tires. Have dealer replace them ... either discerner brand or same brand but different.
I recently went to “national chain” for tire rotation and balance and ended up with a vibration that they were unable to resolve inthree separate attempts including road force balancing.Finally the tech took me to the machine to show me that I had a bent rim; after I demonstrated a technique that proved that theory false, he then attempted to tell me I needed a new tire. When I told him that was fine, replace it, it’s got road hazard warranty thru company (in presence of manager) suddenly they discovered that the wheeel hadn’t been centered properly on the balancing machine. Rebalanced with no issues and has driven vibration free since. Moral ... you gotta stay on top of them.
