2.5 Roadster / Roadster Sport Tire Thread

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?

Yes. Same wheel, same fender, same everything else. So no problem.

I installed Hoosier A6 205 wide front tires (20 psi). Stock front is a 195. No clearance issues. Stock size Hoosier A6 rear tires (22 psi).

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

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

Toyo Proxes R1R - Summer, 140 wear rating

Can we make this wheels as well? I'm interested in upgrading to something nicer. Would love to know my options; what fits.

Added the Proxes to the summer tires

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