Well I was replying to OP, no intention to hijack the thread. I’m glad to see that I do not have to stick to the high load value as this gives more selection. I also have had only Michelin‘s on the car and as the originals were 102 I thought I need to stick to it. Just recently had to get replacement for the Michelin PS 3 and was not able to get as soon as needed and selected Michelin Premacy 3 instead. One thing I might have noticed is a bit quieter ride but not yet sure.
It’s nice to see that new alternative have arrived, I used to use Sailun tyres on my other vehicles, bot bad at all!
(commenting in general rather than at any specific reply): Once you know how to read a tire and the index information on the door of every car, it becomes a LOT easier to figure out that OEM tires are often weird sizes that are NOT the cheapest selections out there, with little (or none!) change in performance by selecting a slightly "out of spec" alternative.
The factory size for the Model S is indeed 245/45 R19 with some variability of load index and either a V or W speed rating.
The reason I selected 235/45/19 which is 10mm narrower (about the width of your index finger!) was that they were $50 cheaper PER TIRE. V speed rating is still excessive, as different tires WILL NOT have any difference in performance over long durations far below those speeds. Since there are ZERO public roads in the USA where you can drive at 150mph, any car that has tires rated like that is for bragging rights not for performance.
What IS important: Having a load index that is more than sufficient to carry over 1/4 of the vehicle load, and when considered as a pair, near or above half the vehicle's full load. Under extreme maneuvers, nearly all the weight of the car can be carried (momentarily) by just two of the tires, so it is beneficial to have that kind of strength available for consistent control. Outside of that, tires are selected for a vehicle to carry far more (oversized) so that they can be pressured far LESS than the maximum, for a soft ride (or because the owner doesn't pay attention to the pressure loss over time). So it is an added "idiot factor" to oversize the weight limit. If you aren't an idiot,
then you can choose from a wider range of acceptable sizes.
The MOST important thing on any tire is how it handles everything OTHER than a dry sunny day. Wet traction. On this, the CrossClimate2 seem to be punching far above their class, b/c they have not been phased on my cars by snow or rain at all, and only marginally less grippy on ice. Very impressed with them, and as I said - I am NOT a Michelin fanboy. I actually hate their tires, or have until I tried these. Now I have them on four different family vehicles.
FYI: "noise reduction" foam inside of a tire doesn't seem to do anything other than make it impossible to fix a flat, and more expensive of a tire. Noise profiles are controlled by the outside tread shape, and the CC2 are also pretty good in that respect.
