    I'm pretty sure that on the 2.0 Sport (USA model at least) the standard tires were the 048 and you could optionally "downgrade" to the 07 (this is what I did).

    Thanks for crediting me for finding that chart.

    The A048 are "sticky as hell" in warm dry conditions though. ( If you want extreme summer performance. )
    But they don't last very long. They are practically track tires, so I can see how some would prefer the AD07 even on the sport model.

    It doesn't make any sense that the AD08s don't come in the same sizes as the AD07s. I e-mailed Yokohama and got a response saying the simply don't make the front tire size for the AD08s.

    I went to Yokohama's website and sent them an e-mail. I doubt it'll make a difference but maybe if enough people contact them they'll produce the AD08s in 175/55R16 size. Even if they only produced a single batch, people could store them in their garage (front tire size at least).

    This is from personal correspondence from Roger Reid for his Roadster Sport... but he also mentions it in one of the autocross results threads.

    That was my thinking in downgrading to the AD07s on my Sport.
    With them I'm replacing the rears twice a year; the 048s would probably more than double that rate.

    I've had my Roadster Sport about 3 weeks now...I opted to go with the AD07's rather than the A048's simply because I will be using my Roadster to drive to work...I don't have the luxury of only using it in fair weather so I felt that I needed to include wet weather performance that the A048's probably wouldn't provide.

    It is my understanding (I asked about them) that the AD08's have not yet been approved for use on the Roadster (probably as dsm posted due to improper sizing at this point in time.)

    I've swapped the rims & 07's for the standard rims & Hankook's for winter driving.

    From the above link
    They added sizes but didn't keep all of the AD07 sizes, including one of the ones we care about?

    At the same link it says:
    Tirerack.com shows the minimum temperature for both 07 and 08 as 14 (not -14) degrees Fahrenheit:

    I just called Yokahama Tires and spoke with customer service to request that they make the front tire size in the new AD08s. They took my information down and said a product specialist would get back with me. Maybe if enough people call, it might help.

    I had thought about that but some people recommend against mixing tire types. I guess I'll just keep using the AD07s until there is a better option. They seem like really good tires to begin with so no problems. It's just that the AD08s are supposed to be better so if they were available, I'd use them.

    Toyo makes a few different tires that fit the Roadster (Sport). Pick your stickiness vs tread life. I'm having the R888's put on my car now. I'll report my findings. The 100 wear rating is right about where I want to be, traction vs tread life, as compared with the 60 wear rating Yoko tires that come stock.

    Toyo Proxes R888 - Summer/Track, 100 wear rating
    Toyo Proxes T1R - Summer, 280 wear rating
    Toyo Proxes 4 - All-Season, 300 wear rating

    Don't remember where, but I read that you can fit the Front 195/50/R16 without problems on the Non Sport Roadster. Can you people share some opinions and toughts about that?

    If 205 wide front tires work, then this tire becomes a possibility:

    Then why this choice in tire size difference between Non-Sport and Sport from the Tesla people on the standard equipment? Can you explain?
