Kdw, I am sure that the majority of class racers have tried both the 92 and 94 inch tires. The rpm difference will be 150-200 …As far as ET , there are so many variables from car to car…..is your first gear a 2.52,2.75,2.85,2.91 ??? The same holds true for rear end gear …Weight of car could also determine what tire it likes. It’s something you just have to try at the track …
