    Thanks. If I only get 10% more miles from the AD08s I will be disappointed, given the extra cost.

    The price seems to vary. The AD08's were less expensive than the AD07's when I bought them last. I expect better performance, but not longer life out of them.

    The Pilot Super Sports may be rated one level below the AD07 and AD08r but they perform more like an extreme performance tire. In fact I would say better than most extreme performance tires. Most days I can't tell the difference between Michelins and the Yokos. Unless it's raining, and then the Pilot Super Sports get much better range and performance.

    The Michelins last longer than any of the other choices, are slightly quieter and currently on sale for $134. It may sound like I'm advocating for the Michelins. I'm not. I'm just offering my own experience.

    Note that I was talking AD08r, which is actually different than the AD08, at least according to Yokohama.

    Finally it is spring so I just changed to new summer tires from winter's Blizzak WS80. We had saved the original tires planning to put them back on in summer, but then upon realizing they were 7 years old (even though only about 7500 miles) we decided the safest thing to do was to replace them.
    Original tires were:
    Front: Yokohama A048 ultra high performance (streetable track) 195/50/R16
    Rear: Yokohama AD07 225/45/R17
    We got a quote from Tesla for $1200 for tires and installation. Furthermore, they said they would use AD07 in front and rear, but AD07 do not come in the 195 width so they would have installed 175 in front. We didn't want to get the A048 because they are not good in rain so we were worried about safety since I won't be taking the Roadster to a track.
    Instead, on TireRack we purchased Yokohama Advan Sport V105 Max performance summer (195/50/R16 and 225/45/R17) with installation at local NTB (all for ~$700).
    TireRack does not seem to know that Roadsters can have 195 front so this tire does not come up in the search for tires by type of vehicle so you have to do the search manually. Do all Roadster Sport models have 195 front width or was that optional (perhaps only with A048)? What have others done?

    Yes, that was the optional fitment for the A048. I'm running DZ102's in the sport size on my base Roadster and all is well. It really opens up your options if you run the optional fitment.

    We've been through 2 sets of tires mainly for autox use. Both sets were Bridgestone RE71R

    2016 season
    F: 205/50r16
    R: 235/45r17
    Tall sidewalls, but fit according to manufacturer spec.

    2017 season
    F: 205/45r16
    R: 245/40r17
    This year we decided to pinch on tires with a shorter sidewall in an effort to bring the motor's powerband inline with the low speeds of an autox course. The pinched tires seemed to like higher pressures than recommended (+3-4 lbs). We'll probably stick with this size next season unless different sizes are released in a different compound.

    Here's a list I made of competitive autox tire sizes, and if they are similar to the stock staggered circumference
    Code:
    Stock
      175/55r16
      195/50r16 (alt)
      225/45r17
        Circum: 74" (74.3” alt) 78.4" +5.9%
    
    2017 Season
      205/45r16
      245/40r17
        Circum. 73” 77.6” +6%
    
    2016 Season
      205/50r16
      235/45r17
        Circum. 75.6" 79.5" +5%
    
    
    Optional
      205/50r15
      245/40r17
        Circum. 72.4" 77.6" +6.9%  MAYBE?
    
      205/45r16
      225/45r17
        Circum: 73” 78.4" MAYBE?
    
      195/50r15
      225/50r16
        Circum. 71.2" 78.1" +9.7%  NO
    
      195/55r16
      245/40r17
        Circum. 76.8" 77.6" +1.2%  NO
    
      205/50r15
      225/50r16
        Circum. 72.4" 78.1" +7.8%  NO
    
      205/50r15
      225/45r17
        Circum. 72.4" 78.4" +8.2%  NO
    
      195/50r15
      225/45r17

    I forgot to mention that in my quest for autox tires I did a lot of research on fitting 15" diameter wheels on the front. Long story short, a 15" wheel wont clear the brakes (the rotor is a larger diameter than on a Lotus Elise). CCW was the only manufacturer that said they could build some one off wheels CNC'd from a solid block of aluminum that would fit, but that exceeded what we were willing to spend. So, that is why there are some tires for 15" wheels listed above.

    If only they made Pilots to fit the Roadster's front wheels.

    I am loving my Dunlops however. They just work - hot, cold, rain, (stayed home the 2 slightly snowy days we've had this year so can't comment on that), you name it.
