This is another one of these countless threads on the internet dealing with vibrations, but here is an issue I am having. New 2018 X5 came with a set of OEM Michelin Latitude Tour HP ZP Star RSC BMW, Run Flat tires, 255/50R-19 on style 449 rims. They served me well and lasted until May of 2024, when they were worn out. All these years the car drove silky smooth with zero vibrations.
In May of 2024 I got a set of the same exact tires from Tirerack, with the same RSC BMW Original Equipment designation. Had them mounted by a local reputable tire shop that I've been coming to for decades, balanced on the Hunter 9700 machine. Drove the car and felt vibrations at 55+ mph. Not anything major, but I'm very particular, and even the slightest vibrations bother me.
I took it back to the shop, they put the wheels back on the balancing machine, checked them with all the old weights still attached, and all four were out of balance by as much as 1.5oz. They took off the old weights, rebalanced all the wheels, but the vibrations persisted. I didn't have the time to go back, so I was just ignoring the vibration as they were rather minor. I thought that maybe something is wrong with their machine, as all 4 tires were out of balance two weeks after the original balance.
I have since put on maybe 5k on the car, and today I decided to address the issue, and took the car to a different shop. All four wheels were out of balance when they put them on their Corghi machine, but to make matters worse, all four of them would not zero out - the machine shows the initial amount of weights to be installed, and after they get installed it keeps asking for more and more. The technician said he has never seen anything like this, and he was completely puzzled on what could be causing this.
I know my rims are not bent as I've never hit any potholes, and old tires were butter smooth. I've seen threads of people having issues with acoustic foam separating inside the tires, but I don't believe this particular tire has such foam? I've read Michelin moved their production to a different country, maybe I got a set of subpar made tires?
As a last resort I can take these tires back to the shop with the Hunter 9700 and ask for road balance, but i don't know if it's worth the bother. Maybe I should just get a set of non run flats?
