Inconsistent Rumble/Vibration at 80MPH...
I recently got new wheels and tires. From what I understand, the stockers are 215/45/17's mounted to 17x7 wheels with a 50mm offset. My new wheel/tire combo has 205/40/17s mounted to 17x7's at a (I'm guessing) 40mm offset. With the new wheels and tires, I get a very pronounced vibration through the steering wheel when I hit 80. Not before, and not after, but at 80, and 80 alone when it happens. It's not consistent, though. Sometimes it's there, sometimes it's not. It's similar in feel to when your tires are hella worn and the wheel wobbles, but this is "tighter" and more controlled somehow. I don't think:
1.) the tires are worn, because they're brand new.
2.) the tires are unbalanced, because WheelsNext claims that they're "Roadforce Balanced" and I can see the little weights glued to the wheel.
I can't help but think that if it was the wheels/tires at all, that it'd always be present to some degree regardless of speed. Perhaps it's just enhanced feedback due to the smaller tires? It's only at 80mph, but I only hit 80mph on the same freeway.
Does it sound like the road surface or does it sound like a wheel/tire issue??
