315/30 18 Tire Review Highlights

Nankang NS2R rated 77% while driving a Toyota Supra
Driving on a combination of roads for 2000 spirited miles
315/30R18 (200tw) on the rear and 265/35R18 (180tw) on the front. 600 WHP Toyota Supra. I was pleasantly surprised with these tires. I wasn't expecting much given the price tag but they have performed better than expected. Started them at 40psi all around but have since dropped to 35psi on the front and 32 psi on the rear, this seems to be their happy spot for my car (1550kg) on good roads. I initially just got them to make sure I could fit a 315 on the rear (rims are 18x11) but I did also want to see if they were going to be a viable tire that I could thrash on. They take abuse very well and are lasting way better than expected. Downsides are the road noise and comfort which is to be expected. The straight line grip is NOT as good as I hoped for given the massive 315 in the rear, but lateral grip is good. When they do lose traction I found it to be quite predictable and very user friendly. These would suit an endurance event, drifting or even daily driving as long as you don't mind the high noise levels at highway speeds. I have not used them in the cold as I live in a very warm climate in Australia. The guys from Apex use them a lot on the Nürburgring for their cars, if it's good enough for them then I would say they are decent tires.

Continental ExtremeContact Force rated 71% while driving a Chevrolet Corvette C7 Z06 2016
Driving on track for 1600 spirited miles
I purchased the Conti Forces in 295/30/18 and 315/30/18 for autocross and track use on my 2017 Z06. This summer I ran eight autocross events and about 1500 road miles on the tires and I've been pleasantly surprised by the life they're providing. Should easily be able to get through next year's track season on the same set. As a 200TW track focused tires, the dry grip is tremendous as expected. Wet grip... exists, but they definitely don't inspire much confidence in the rain at any speed. They are rather loud on anything other than a pristine surface, but that's to be expected. I'll probably try another set when these are worn out, hopefully someone has the 345s in stock at that point.

Toyo R888 rated 94% while driving a Toyota supra turbo
Driving on a combination of roads for 25000 spirited miles
This tire is amazing for an every day road tire and the occasional track day. It warms up almost instantly and puts the power down well. When it rains I have very little worry as I can still put down all 600whp, stop extremely well and be very confident in the corners, weather its sliding or gripping. Most other semi slicks I have used recently are just down right scary when it comes to wet weather.
I can't think of a better semi slick road tire for the price.
