Explain to me Y u would run a harder tire just to soften it? Idk this and I feel like I need more explanation lol
Like said above in a post, the 22 or 33's when prepped down will roll better and make more speed if you can get them to hook up. Try finding an old set of 33's first and give them a try with a prep that gives you alot of bite. You may also try running a little less left side weight in the kart to help make some sidebite in the turns and give you a little grip, but if it were me, id make the grip with tires and leave the chassis alone if your setup is good.
