So my 2018 M3 LR AWD will be 5 years old this November. Recently started hearing weird road noise, which I thought was related to the recent work that they did (rear drive unit failed, they replaced it). I took it back (walk-in), had a tech with me on a test drive in my car, I demonstrated the noise (which was like a helicopter), he thought could be tires, but not sure. I scheduled an appointment for them to look into it further as "rotational groan". On day of appointment, tech (someone else) rode with me again to diagnose. He thought it was tires. They asked me to leave the car to diag further.
Day later, they said I needed new tires at 27.5k miles (I was still on stock 18inch Michelin Primacys), saying my tread was almost gone. The said, the placed loaner wheels (with its own set of tires) on my car and the noise went away. I asked them if they could put my wheels on another Model 3 and see if the noise is still there, but they wouldn't go the distance on that request. They quoted me upwards of $2k to replace tires and performing a wheel alignment. I declined service, I picked up the car and paid a diagnostic fee, which was negligible.
I then did two things:
1. Took the car to Goodyear for the free alignment check (image attached)... They don't think car needs alignment, according to them alignment is spot on, but I think it can still be tweaked further. Tech was fairly knowledgeable and said the wear is mostly due to vehicle weight and the instant torque.
2. Bought a tool to check my tire tread. Fronts at 5/32, Rears are 4/32 and 3/32, and never did rotation, so I do agree tires need changing. Settled on Vredestein Quatrac Pro.
So my question is: Before/After/When having the Vredesteins being put on the tesla 18" aero wheels, should I have the alignment tweaked further. If so, what would I want to tweak to maximize tire life and have even wear (I will be performing rotations every 5~6k miles after the Vredesteins are on). I don't feel the car pulling. I drive with the steering in sport mode, mostly as a hyper-miler with chill-mode accel, but perhaps I don't feel the car pulling even though it may be very slight (not sure). I don't really launch the car, unless I am demoing to someone who hasn't sat in the car, which probably is once in a year (tops).
My goal here is to minimize tire wear and extend tire life, and I bring my car to a relatively slow speed before cornering/turning and consider myself to be a good judge of when to release the accelerator to allow for one-pedal drive (rarely put foot on brakes). Any recommendations/suggestions. Please let me know ? I'm very keen to get the Quatracs on!
