Thanks Jon! I got put in a bad situation with my newest GYs getting damaged. I bought a set of Hoosier JR fuel tires. Heavy= slow. In talking with Hoosier ,I'm told the next run of their #18350 will be lighter. I have a set of GY 2585s that will get us thru the last race of our season.
Good luck to all and a BIG thanks to to those sharing info here. George
