I know I'm opening up a can of worms as far as tire makers. I have a 1972 Dart strictly strip car with a 360 in it. The wheels are 15x7 Auto Drags with 3.25 back space. Not sure which tire to get Hoosier slicks 26x9.0-15 or ET Drags in 26x8.5-15 any in put? Also how much would I lose in gearing going from a 26 inch tire to a 28 inch I currently have 4.10 gears
