Autocross / Solosprint tire size

Hi all, I am looing for DOT race tires for solosprint and can't find anything listed in any size that's close to the stock diameter... Anyone has some ideas ? What do you use ? I have to buy wheels, so 17" or 18" will do...

Thanks !

I found the Falken Azenis RT-615, size 255-45-18 which has the same diameter, has anyone experienced this size ?

Why do you need to have the stock diameter? I run 275/40/17 Kuhmo V710s. Everybody in my class runs this tire in various sizes.

I thought you had to have more or less the same diameter for ABS and the various TCS sensors (obviously the speedo is not a concern). Thanks for your help !

If you have an SCT tuner, you could enter the different tire size. I've done this, but didn't notice a difference, so I don't bother with it anymore. Also, if your ABS is kicking in frequently, you might be braking too hard, too late. As for the TCS, I now keep a post-it on my steering wheel while at the track that says "TURN TCS OFF!". When I forgot to turn it off, my times would be almost a second slower.

That and using that size is like putting on a set of 3.73 gears, don't worry about the ABS since you'll only be using them on an Autocross course, also you should have TCS turned off when you run.
