What size(s) are you looking at? 225/50r15 and other similar sizes for the A052s are pretty pricey from what I'm seeing. They seem to be very good tires, but I wonder if it's worth the extra over something like an RT660
I would try a 225/50/15, only a little taller than the 215/45/16 I’m currently running. I have ran the RE71R, RT660, and the Rival S on this car and I would have to say the RT660 is my favorite of the three but my second set had center rib issues, which lead me to try the Rivals which I am currently running.
That being said the A052s seem to be without a doubt the fastest tire for autocross, but it does have its downsides. They work best on cars with large amounts of camber, they wear more aggressively and I have been told they can drop off performance wise fairly quickly. I’m still considering giving the RT660 a second chance but I will also have to find a place that that has them in stock. Last I checked Tire Rack said they were back ordered until June.
