98 z28, on the highway my steering wheel shakes, but the car drives straight I don't need a wheel alignment. I just got some PZero rosso tires, they were balanced.

Unbalanced tires, Warped wheel, suspension part bent/worn???? How old are the shocks??

Rack and pinion worn??? Could be 1 thing or mutiple things....

Could be the tires breaking in.

I would do a couple simple checks, confirm good tire pressures on all the tires and also make sure all the wheel weights are in place. If you feel everything is in order and nothing suspension/chassis wise is worn out or damaged, then I would call the shop that did the mount and balance. There could always be a slight chance that the tires were not balanced correctly.

rotate the tires,if the shake goes to the rear than you know it has something to do with the rims or tires.could have a bad tire!it happens

i'm going to take a drive with the cam, so you can get a more in depth view

not likely. If you just put on tires and now the steering wheel shakes, there is your problem.

never drove it with any other tires on it

Sounds like tie rods. If it's high mileage it could also be A-arm bushings.

it's got an intermediate roll, kinda like a musical beat

my lower control arm is crushed!

your lower control arm is crushed?????? well.. I can only think of one way THAT can happen without hitting something major that you would definitely feel.. and that is if whoever was doing your tires jacked it up wrong... or while up it slipped and landed on the Control arm.
