Consumer Reports does not know a performance tire from their *ss. Check out Tirerack.com. They actually have people with track experience testing tires not people who also write about washing machines. The primacy is a no-grip all season tire, not a high performance tire. The Conti has less grip and the PS2 is an older design than the PSS.

I contacted Tesla and they said that resetting the TPMS would re calibrate the speedometer. The representative mentioned it could take 25 mi of driving.

Your reasoning makes no sense. You do know that different people test the tires than do the washing machines, right?
Tesla also sells T-shirts and wallets. Does that make their cars any less awesome?

The issue under discussion was rolling resistance, not performance or grip. Tire Rack does not rate rolling resistance. In fact Consumer Reports was the only place where I could find ratings of rolling resistance after 30+ minutes of web searching. And the reason I picked those 4 tires for comparison is because the bottom 3 are the ones that Tesla offers and posters here were interested in how the Pilot Super Sports compare in rolling resistance.

The nice thing about having so many game MS owners is that we will (should.. better??) have a consensus of the affect of moving from PS2 to PSS on MS. I know that I will generate a re-produceable route before I change my rears out and then document running that same route several times with new PSS'. If others do the same the sample size will make up for the inherent inaccuracies in non-professional testing 
We will get a good answer soon enough.
Hats off to the ones that took the plunge first as it paves the way for those of us that will follow.

I drive the same 15 mi route to work every morning. I am usually slightly under 4 kWh consumption. This morning I used 3.9 kWh. I have averaged 259 Wh/mi for April. I noticed the last 30 mi I averaged 262 Wh/mi. My speedometer may still be reading a little high. I will keep evaluating the energy consumption for the PSS that I had installed yesterday.

I just had PSS's installed on my rears today, replacing stock Conti's that were worn down to the fibers.
So far feeling GOOD, running smooth and quiet, with no more fears of having a Blow-Out on the highway!
I will also keep an eye on ongoing energy consumption, affect on range, and rolling resistance...
Uh, how do I evaluate that last one exactly?
LOVE this commercial...

Yep, I am reasonably sure most MS owners only care about rolling resistance for its effects on range so having a good feel for how the tires impact your range would be most helpful.
And going slightly faster or accelerating up a hill will eliminate the rolling resistance gain between tires. To really see the advantage you have to also drive in a manner conducive to getting low Wh/mi numbers.

I skimmed this thread, but didn't see any mention of tire bubbles/bulges on the Pilot Sports.
I bought an 8000 mile inventory P85+ in March with staggared 21" rims and Pilot Sport tires. They each have about 6-9/32 left on them.
Shortly after buying the car (1-2 weeks), I noticed a small bulge on the rear right tire. I've been told that that's a serious problem and the tire needs to be replaced before a blowout. Ok, no problem. I luckily found someone selling two used 21" P85+ rear tires on ebay, ordered and received them.
Today I'm out washing my car, and I notice ANOTHER bulge on the front left tire, and it's bigger than the rear bulge. I go back to look at the rear bulge, and there are now TWO bulges on that tire. I've only put on about 1,200 miles since I bought the car, and haven't, to my knowledge, hit any potholes. I did have the car valet parked last night at Mohegan Sun casino, so maybe they hit a parking bump or something? Who knows.
But does anyone else have this much problems with the Pilot Sport producing bulges like this? I'm pretty sure I'm going to sell these four rims and get 19" Rials or TSTs and some good all season perf tires (like the Conti DWs).
I can't afford to replace $500 tires every time they develop a bulge!

I've got almost 12k miles on mine and I've had no bulges. I've hit several pot holes as well...
No issues with bulges on the 21" staggered and non-staggered setup with PS2's. I looked at Ebay for used tires, but decided against it. Don't know if any tears in the beed and most of them are patched tires. Tires could be worn unevenly since most of the tires on there are probably repaired Tesla tires that may have been flats (in other words, riding on the sidewalls of the tire). I don't know of many / any other manufacturer that uses the 265/35R21 sizes except for Tesla. Spent this much on the car and value my life, I'll spend the extra on new tires.

I had 13400 mi on my Pilot Sport 2 with 5/32. No bulges. I like the Pilot Super Sports better for ride quality and they will probably last longer.
I have a P85 that had the21 inch Tesla wheels with Michelin Pilots. I found the Pilots to be very easily damaged from potholes and even speed bumps. Where I live, speed bumps are located every few hundred feet. In order to avoid damaging the tires, I would have to stop just before the speed bump and then proceed over it at less than 10mph.
I recently replaced the wheels and tires with the Tsportline 19 inch turbine wheel and Michelin Pilot A/S 3 tire. My initial impression is that the A/S 3 tire is quieter, and handles the potholes, speed bumps better that the 21 inch Pilots. However, the 21 inch Pilots have better traction from a stand still. Flooring the accelerator with the 19 inch A/S 3 tires causes the traction light to flash repeatedly. This does not happen with the 21 inch Pilots. I also like the appearance of the low profile 21 inch tires better than the 19 inch tires. However, I feel the 19 inch tires are more practical in the DC area, due to the potholes in the roads and the speed bumps where I live. I have not noticed any difference in range with the 19 inch tires. Maybe that will change after I put my mileage on them.
I haven't decided whether to sell or keep the 21 inch Tesla turbine wheels and Michelin Pilot tires (with the TPMS sensors). The tires have between 6/32 and 7/32 inch of thread left after 8500 miles. As I said above, I like the look of the low profile tire better than the 19 inch regular tires.

although not on a model S I have run PS2, PSS and now just put the A/S 3 on an M3 (19 inch, 35 series). The super sports were much better than the PS2 for both grip and longevity. Both were noisy and seemingly transmitted every bump.
As of all of 2 weeks experience on the A/S 3 I think they are quieter but seem to have lost some grip/ roadfeel. Seems like the sidewalls aren't as stiff.

1. Are you sure it's a bulge and not an indentation? An indentation is an indication of a carcass ply splice and is not a problem.
2. Are you keeping the pressures up? Your only defense against pothole damage is the pressure you keep in the tires. The 21" tires are particularly vulnerable as there is little sidewall to absorb shock. The vehicle placard pressure should be the minimum you keep in them for normal street driving.
3. 19" tires are far more robust and about half the price.

I'll check the pressure tomorrow.. I've only had the car 2 months and 1200 miles, but good idea to check.
In terms of 19" tires, I have a terrible dilemma to sort out. I just can't decide what to do!
I *really* like the look of the 21" (staggered) rims, but do not like the $550/tire replacement costs. So I'm thinking of keeping the 21" rims with different tires for summer driving, but go 21x8.5" all around.
Scenario #1: Buy two 21x8.5" rims for the rear, sell the rear 21x9" rims. Widens the selection of possible (matching) tires at a much lower price point and allows rotation
Scenario #2: Scenario #1, but also buy 4 19" rims (Rials or Sportlines) with all season tires for cold winter driving (but not in snow, I have an ICE for that).
Scenario #3: Sell all 4 21" (staggered) rims, and then Scenario #2 for year-round driving (say, with the Michelin Primacy tires or maybe ContiProContact DWS)
Right now, I have bulges on the Front/Left and Right/Rear Pilot Sports. I have a replacement for the Right/Rear tire. So to be safe, I need to find one 21"x8.5" tire (waiting on ebay for that -- I can't fathom buying a new one!). So to buy two 21x8.5" rims (for the rear), they're about $600 each on ebay (only one available now, so I'd have to wait for another), then buy 4 new 21" tires (maybe the Continental ExtremeContact DW).
I hate to compromise the design considerations of the P85+, but I think I'm leaning toward Scenario #3 as much as I hate to not run the 21" rims in the summer.
Such is life in New England. I think in the short term, I'll get one more Pilot Sport to replace the Front/Left tire for this summer (assuming no more bulges!), and then replace them all with Rials+Michelin Primacy (or Conti DWS) for year-round driving.

245/35ZR21 will work on a 9 in wheel; so, there is no need to replace the rear 21" wheel. We suspect the Pilot Super Sport will be available in a 265.
