You're right. When I looked at first, I looked at the 265 size which is $299. That's interesting they make the 245/45-17 for $100 cheaper.
The AD08s are looking a lot better now if they make zero difference for street driving (non-track use).

Sorry, you're right - I read the wrong line. In fact the AD08 rears are $199 versus $354. I'll edit my earlier posts.
And yes, if you go to a Canadian source the price sucks. I've been ordering my tires from TireRack in the USA.

Thanks for the feedback Bob. Didn't realize you still had the Yoko's up front. Could be an interesting compromise to keep stickier tires up front and cheaper tires in the rear...

I am confused again... Tirerack has this comparison:
Consumer Survey Results By Category
Now I am starting to like the Bridgestone Potenza RE 11's:
BridgestonePotenza RE-11
Looks like they are better all the way around when compared with the Yokohama's and they are $212. Anyone have any experience with these tires? I saw someone was asking about them earlier in this thread, but I didn't see any positive or negative feedback.

Here is my conversation with Nolan at Tire Rack. I am really getting close to pulling the trigger on these Bridgestone Potenza RE 11's...
Thank you for choosing Tire Rack. A product specialist will be with you shortly.
You are now chatting with 'Nolan'
Jordan: Hi there, I have the Yokohama AD07 on the back right now, but am looking for a more cost-effective solution.
Nolan: Hello Jordan, how may I help you?
Jordan: I was considering the AD08's but someone suggested the Direzza Sport Z1 Star Spec
Jordan: The car is similar to the Lotus Elise, but is about 30% heavier at 3000 lbs.
Jordan: I was told that the Dunlops are actually stickier than the AD08's. What can you tell me about their weight-handling ability?
Nolan: I can help with that
Nolan: Both tires have a focus on the dry grip and are not going to be the best in the wet. Do you have the Yokohama AD07 on the front and back currently?
Jordan: I don't track the car, and most of the time I don't drive too aggressively (but I do like to accelerate from the light from time to time ;-)
Jordan: As far as I know, the AD07 is the only tire available on the front.
Jordan: I live in Florida, so it doesn't get too cold here, but it does rain. Normally, on rainy days, the car stays in the garage, but I do get caught in the rain from time to time.
Nolan: The Dunlop is a great tire and one of the top rated. What is the front and rear sizes you are running?
Jordan: 225/45R17 in the back and 175/55R16 in the front
Nolan: one moment while I take a look
Nolan: You are correct, the only matching are the Yokohama. We don't recommend mixing tires as it will cause more unpredictability in the handling of the vehicle. It can be done, but not recommended
Jordan: I have read this also. A lot of other owners are going with the AD08's in the back as they are significantly cheaper and give a little longer life. I was told the Dunlop's are even better at traction and life expectancy. The problem, as I understand it, is because the Roadster is so much heavier in the back and has such incredible torque, it eats the rear tires (6-7K miles, if you are lucky!)
Jordan: Another issue is that the Roadster uses a sensor on the front wheels to monitor rotation. If the rear wheels rotate too fast, it engages traction control. As long as the rear wheels are more sticky than the front, I think this will be OK.
Jordan: Sorry - too fast in relation to the rear wheels.
Jordan: Can the Dunlops support the extra weight?
Nolan: Yes, this can handle the weight
Jordan: And would you agree that the Dunlop's are stickier than the AD08's and may last longer?
Nolan: They will both be a very stick compound. The AD08's currently hold our track record in the dry. The Dunlop
Nolan: The Dunlop would be better in the wet
Jordan: Ahhh so how "close" are they in dry and wet conditions?
Nolan: Click here for the survey ratings
Jordan: So if I'm reading this right, the Yoko's are a little more comfortable, better in steering response, quieter, and have a better treadwear?
Jordan: As far as steering response goes, if they are in the back, this does not apply, right?
Jordan: How much are the Potenza's?
Jordan: When I go to the Potenza page, there is no price.
Nolan: one moment and I will take a look
Nolan: The RE-11 is $212 per tire for the rear size
Jordan: I assume they don't have one for the fronts?
Nolan: Unfortunately they do not
Jordan: how do the AD07's and RE-11's compare as far as stickiness and composition?
Nolan: The RE-11 is going to be the stickiest tire with the most grip available for a street tire.
Jordan: And they can handle the weight also?
Nolan: Yes
Jordan: Excellent! I am posting in the Tesla forums now to see if there is anyone with experience with these tires. I know there are many who are using different front/back tires. This may be the solution for me. Thanks very much for your help. When I go to purchase them, should I mention your name?
Nolan: Please do and I will be able to monitor your order as well. If you have any further questions, feel free to contact me at 1-800-428-8355, option 3, ext 173 or [email protected]

He was talking specifically about the AD08's and the Dunlop Direzza Sport Z1 Star Spec's not doing as well in the rain. According to their chart, the Bridgstone's are best in nearly all categories.
The AD08's are definitely quite good in dry conditions, although not nearly as good as real "stickies" like the A048. They are decent in the wet, like the AD07's. The A048's absolutely suck in the rain.
In my somewhat limited experience - one autocross day in the rain w/ the S2000 - the Direzza Sport Z1 Star Specs are pretty good in wet conditions. In dry conditions they are excellent - I've done 3 full day track events, 2 evening track events, and a bunch of autocross days and not only did they grip really well, they're still in great shape after all that abuse (enough abuse that my S2000's front pads are shot).
I have Michelin Pilot Super Sports on my Inifiniti. I recently ran it at Le Circuit Mont Tremblant because my S2000 didn't meet the bimmer club's (over-the-top) convertible rules. It was dry the first day, and they did very well considering the weight of the car. It rained buckets the second day and they still did a great job. In fact my instructor said that's what he uses for his rain tires.

Michelin Pilot Super Sports update
Today I replaced my Michelin Pilot Super Sports after only 5,000 miles. They were past the wear bars. Michelin honored the 15,000 mile warranty and I only had to pay a small fraction of the new tires. Although I was disappointed with the tread life, these tires had performance comparable to the AD07, better when wet, for about half the price. Actually if you count the warranty comp and assume I'll get 5k out of the replacements, they work out to about 1/5th the price of the AD07s per mile.

Interesting. I wonder how long they'll let you keep that up (getting 66% off due to tread warranty)?

OK - you have my attention!
Here are some questions:
How do you use your car?
Do you notice anything strange (from traction control mostly) about dissimilar tires?
Do they squeal or chirp at all?
Are they about the same noise level as the AD07's?
> Today I replaced my Michelin Pilot Super Sports after only 5,000 miles. They were past the wear bars. Michelin honored the 15,000 mile warranty [hcsharp]
LOL!! I just put on the same, but Discount Tire gave me a 30k mile warranty. Guess I'll have to run these down to the steel mesh, fishtailing & sparks flying at every lauch. Its the least I can do in the face of such confidence.

How so? The tread life sounds better than what I've been getting with Yokohamas.
Face it, any soft compound tire intended for high performance cars are not going to have high tread life, especially when we beat the crap out of them with an electric motor.

I just replaced my AD 07's with the AO 48's...noisier, but more fun on dry pavement...when it's wet,
I just scale back my driving aggressiveness...not that hard to do and more than a fair tradeoff for the improved dry weather performance imo...

The warranty says you can only do it once. I don't know if that means I can pay full price for a new set and do it again when they wear out. All I know is I cannot do it again with the pair that's on the car now.
I don't think I drive all that aggressively but once in a while I floor it and occasionally take corners fast. Never on a track (yet!). Not a problem with AD07's on the front but I have a version 2.5. No squeal or chirp (with TC on). Acceleration is comparable to the AD07, better in rain, range is slightly better with the MPSS. I do notice a slight difference on initial turn-in but ultimate grip is virtually the same as the AD07. The MPSS noise level is lower on a smooth road, louder on rough roads, and louder when you hit things like expansion joints.
I got better tread life than with the Yokos too. My expectation, and consequent disappointment was based on the 15k warranty.
Just keep an eye on the wear. When your rears get low on tread these tires hydroplane at a blink of an eye, especially at 100 kph. Also they have terrible rolling resistance when the temperature drops close to freezing. But for grip nothing beats them on hot dry pavement!
Discount tire doesn't warranty anything. Michelin does. And if you read the fine print it's only 15k miles. A couple other points: Most tire shops won't handle warranty claims if you buy the tires online. A Michelin dealer has to be able to measure the tread depth in three places across each tire to ensure that your alignment is good. So if you run them until they're bald, you have no warranty claim. You also have to make sure the installer signs your mileage log when installed to verify the odo.
I just checked the tread wear on my MPSS and I'm down to 2/16. Based on previous measurements I'm predicting I will hit the wear bands at around 7K miles. I got 6K out of the last pair of AD08s and I wore those well past when they initially hit the wear bands, so it looks like I'll get somewhere between 1K - 1.5K more on the MPSS than the AD08s. I replaced my initial pair of AD07s at 7K, but those were pretty far past the wear bands as well. Looking forward to seeing how the warranty works out on the MPSS when I replace them (probably not until next spring).
Okay, my AD08 rears are spent. They lasted 8,500 km (5400 miles). That's about 50% better than the AD07s.
My (original) AD07 fronts have approximately 20,000 km on them (they were off the car for about 10,000 km while I was using T1Rs) and they still have plenty of wear left.
(Yeah, I have a heavy foot.)
