Strong vibration on highway..... help

[Jedurso]

Hi all. 2010 yaris. 105 thousand miles. 500 miles highway weekly.
So, I have a strong vibration and pulling to the right. Most notiable on highway. Took for an alignment, didn't help. Took back 3 days later, realignment, didn't help. Say it's suspension.... okay. Tire rods are fine, control arms are fine. Where am I looking????? I have new spark plugs, coil packs, fuel injectors, and belt. Also took off and cleaned my throttle body and rear breaks are a month old. I do need tires.... can it be that simple?. Please help, this is my only vehicle and it has to last.

Try rotating tires around, check tire balance, you can have them put the car in the air and with the car on accelerate spinning the tires to a speed to see if the what wheel is shacking vibrating

You overlooked the tires. Check for dammage. Balance check. Good luck!

Yes it can. If you've had an alignment and checked the suspension as you say then that's what we have left. I would have started there first.

Get some new rubber.

Thanks everyone, ordering a set now. I'll update when I have them

And the only reason I didn't go there first is because I still have some meat on them and this came on kinda sudden. Not night and day sudden, but progressive over two weeks or so.
