Michelin MXM4 on MY?
Has anyone put Michelin MXM4 AC on their MY? (I know a version of these came with the M3.) Not happy with the OEM tires so I’m replacing them. I wanted the AS/3 but they are back ordered. This is my wife’s car though and she prefers comfort > performance, so I think it’s OK but not finding anyone else running these with the Y.
Thanks!
Update: I ended up contacting Tesla and will be replacing two tires.
Backstory: I had Discount Tire (DT) patch a tire two weeks ago. Thought everything was good until we got on the highway and was going 70+ miles an hour. Car started shaking. Took it to DT again and had them balance again. Same thing on the highway. Intermittent shaking. Unfortunately, now I have to take it on a road trip. Not fun.
So when I get back, I'm like "screw it, replace all 4" (I know, kinda rash).
Anyway, went to DT and the only tires they could get within the next week are the MXM4. The problem though is that their speed rating is lower, and that didn't sit well with me, even though they were pushing it as being OK. Just finished doing a bunch of research on speed ratings and the gist of it is that it is way more than just how fast you will drive. There are other factors, and with it being an electric car with a ton of torque, you really do need the stiffer side walls (especially when not doing winter driving). Additionally, whenever you get a tire patched, the speed rating of that tire is actually lowered. To what exactly, don't know, but it isn't as structurally sound anymore. So my hypothesis is that the shaking on the highway is due to the patched tire. I also wouldn't be surprised if the foam wasn't gutted when DT patched the tire either. That's noteworthy because the foam can separate (if cut) and if it does, it can cause shaking at highway speeds too.
So, just having Tesla replace the two tires (fortunately the patched tire was done on a tire that was 4/32) and doing an alignment. (They recommend doing an alignment whenever you swap tires, but not when you rotate tire).
BTW, the SKU# for the Goodyear Eagle Sport A/S tires that come with the Y is 118255-00-A. 255/40r20.
Sorry for the book, but maybe this will help someone else down the line. In short, I would suggest avoiding MXM4 on the Model Y.
