17” vs 18” wheels - pros/cons for 90/10 street/track?

[S14]

Ok now you guys got me thinking 17s. You’re right on 10% being ally, probably closer to 95/5. But isn’t 17” tire availability only going to get worse as time goes on? I don’t really care about aesthetics, I kind of like the meaty tire look.

I think 255 and 275/40/17 have a strong enough market to stay around for a long time. Falken just released the RT660 in 275/40/17 and some say it's as fast as the RE71r in auto-x settings.

C5Z's use the 275s so there will be options. Street tires is abysmal but for track day tires you should be good. I got my NT05's for cheeeeeeeep.
