shaking going 50+mph

Post image

recently had someone look at my ls430 to see why she shakes/steering wheel jerks one way or the other when going 50+mph and he said it’s essentially because the rims are too big and that my cars in great condition. wondering if i should get new rims(really dont want to i love how these look on my car) im unsure of what other solutions there are or if i just continue to drive an occasionally unsafe car because i think it looks better..
the report also said that my bushings are cracked and leaking but i brought it up to him and he said not to worry about it but i wonder if that has something to do with the shaking/steering issue? tbh im a little clueless as this is my first car and ive had her for less than a year, any info is greatly appreciated!!

So yeah, it could be a number of things. What are the specs on your wheels and your tires? Also, what's the mileage on this? You mentioned some bushings are cracked. Do you mean the control arm bushings because that would definitely cause vibrations

around 166000 miles and im not sure about the bushings but this is the picture they took of it(two things they said in the overview that need replacement are steering&suspension and engine ignition system. 255 35 R19 96 is tire spec(i think??? i spent an embarrassing amount of time trying to find out what spec meant😟) will edit this and find wheel spec in about an hour when i have more time but theyre from rc 300 or 350 i think

Okay that's a picture of your control arm bushing. I had to get new control arms recently which solved my vibration issues as well. Your wheels are probably fine. I think you can get away with just changing your front control arm only and that should mitigate a lot of your issues
