Hello all,
Thank you for contributing to this thread!
Here is an update. Colorado Tesla Service Center will ONLY let me put on the Michelin Primacy MXM4 P245/45R19. I asked if I could put on the Continental ExtremeContact DW. Response was NO, he replied:
"I have seen that tire cause vibration and pull issues historically. The Michelin in our collective experience is going to be your best bet."
I asked it I could put on the Bridgestone S-03. Response NO, he replied!
"The Michelin MXM4 family of tires has been around for quite a while, and has been subject to continuous improvement. The one that Tesla has selected is a fairly recent update to that family of tires, and has the ability to withstand the weight and performance of the Model S.
The Bridgestone is not an approved tire by Tesla, and I personally have no experience with it. As an unapproved tire, we wouldn’t be able to service it nor would we be able to service any aspect of the wheel that would require us to mount or dismount the tire – such as the TPMS sensors or valve stems. We also would not be able to source them nor install them."
So along with only using Tesla wheels, there is only one tire I am allowed to put on 19" approved Tesla wheel. What are peoples experience with the Primacy? I have been running 21 inch wheels and am switching to (Tesla only!) 19inch wheels and tires with all the snow and potholes here in Denver.
Thanks!!
The Primacy is mediocre. I just replaced mine at 40,000 miles with the Michelin Pilot Sport A/S 3. It is superior in every way that you can actually feel. Ride is smoother, much quieter, little or no tramlining versus the Primacy, and surprisingly, much softer over bumps and road imperfections. Cornering and acceleration are vastly superior with the A/S 3. The Pilot Sport A/S 3 is a newer technology than the Primacy, however it is not LRR (low rolling resistance) which means that your energy consumption may increase. Pilot Sport A/S 3 has the same 45,000 mile tread life warranty and is a less expensive tire than the Primacy. Except for the LRR thing, it's a total win.
I read an article recently that asserted drivers are eschewing LRR tires due to the inferior handling and performance of LRR tires. It seems manufacturers are putting LRR tires on their EVs and PHEVs out of a desire to squeeze every last drop of range/mileage from the car, not necessarily picking the best performing tire. This is why I would not necessarily put much stock in what your service center is saying with regard to the Primacy. From my experience, the Pilot Sport A/S 3 is superior in every way, so why not use that tire instead of the Primacy? Oh, right, the LRR of the Primacy allows Tesla to advertise a higher EPA range.
