For everyone looking for a true performance alternative to the F-1's, I finally found the first new alternative that is NOT an SUV or truck tire.
Nitto Tire now has a 255 45R20 and a 275 40R20 available.
Nitto – Fueled by Enthusiasts
The 275 is not even listed on the website yet, but the product code number is 203180.
Pirelli also makes a 275 40R20 in the Pirelli P Zero Rosso line, but there's not a corresponding 255 to fit the fronts. With the Nitto we can now get 4 matching tires to fit.
