I was planning on getting the Goodyear SC3 (non R) but the size I need 305/30R19 has been on backorder for a while. Anybody got some insight on the section width versus tread width relationship of these two tires? The Contis seems to have a really wide section width and narrow tread. Is this for real? I think I may be stuck with the Conti ECF based on my mission and availability but I'm not sure which size to go with. I run 19x11 ET50 wheels square with 25mm spacers up front.

I'm not looking to set records, and all I do is HPDE. I've had Hankook RS4s before and I liked them, so if I could get something similar that would be good. The latest tire I tried was the NT01 in 305/30R19 and I was extremely unimpressed. Pace is less than half a second faster than RS4s on a 2 minute track but lasted less than half the time and get greasier faster.

Couldn't pull the trigger on ECFs. Not many reviews, and some of what I could find weren't exactly positive, awkward sizing.

I decided to take a risk and order the SC3s from Simple Tire despite hearing stories about them shipping old date codes (and they wouldn't confirm date codes for me). They showed up and I'm happy with the dates, but man are these things massive. Maybe closer to a 315.
