If everything was fine, you swapped a tire, and now it's not fine, I'd def suspect that tire. It's the only thing that changed. If it was a wheel balance issue you would get the vibration at a certain speed, regardless if you were pressing the brake or not. How old is the front tire you didn't replace??? If it has substantial wear on the inner shoulder of the tire that could cause a shimmy under braking.

This has gone back and fourth a few times here. Bottom line is that if you're not stepping on the brakes and you're getting a vibration at different speeds you have a tire / wheel / balance issue. Take it to a tire place that has a "Road Force Balancer", have them check the new tire first, it will show you if you have an out of round tire and it's one of the best balancers out there.

Don't know if you're the DIY -type, but I would swap the wheel that's been worked on for one on the rear (or the spare, if the vehicle is so equiped, Well, unnecessary to say, but if you still have a vibration, you can give the wheel and tyre a lower priority in the culprit stakes.

One other thing road force balancing does is tells you the optimal way to mount all 4 tires (match balancing). If you went to a place which doesn't have RF balancing and they simply balanced that single tire separately you may get less than optimal result if the previous tires were match balanced.

if they overtorqued the wheel, ive read that can warp rotors, but honestly, it sounds like bad tire or balance job.
try putting spare tire on and leave new tire off and see what happens.
