I'm looking to run my bike in 300ft dirt drags. Currently I'm running 22" 4 SNOW tires that actually do pretty good. But I want to try some cut knobby tire like the STI Tech 4 or Turf Tamers but I don't know what would be better... The 20x11x9 or the 22x11x9. The bike they are going on is a HJR 4 mil cub 39mm carbs shearer pipes fully dressed plastics. Any help/advice would be greatly appreciated. Thanks in advance!
