Cadillac CTS-V - steering wheel shake

after i changed to nitto 245/40/18's i keep having a shake in my wheel around 60mph so i got them rebalanced an still was there then i got them balanced for the 3rd time at another shop an its still there what else can it be besides tires?

Bent wheel or warped rotors. Try swapping the front wheels to the back and see if the shake in the steering wheel goes away. If it does then one of the wheels is bent.

Warped rotors can do the trick! But if its just now coming about, like said above it is most likely a bent wheel! :(

Assuming balanceing was done correctly, bent wheel or warped rotors. If it shakes when you're NOT braking, then it's the wheel.

If it didnt shake before he got new tires its not a bent wheel. More than likely its a defective tire that is out of round. Road force balancing can detect that.

ive seen tire shops bend wheels but i agree. prolly a shit tire

check the date codes on the tires to make sure they are current and not shitty old stock tires they dumped on you.

Got them road force balance had ten balanced 3 times an the one tire was odd outa the other 3 an I have a slight bent rim but it's in back an if it other is slight bent it's balanced an when I'm goin like 80 100 an hit brakes they feel warped but drivi g around there fine

Why didn't you say that you had a bent wheel from the beginning, that's your problem not the new tires. Until your get a new wheel it's not going the get any better.

No I always had it even with older tires it was fine that slight bent one is rear
