If the Spider Trac's are a 22" then you will appreciate dropping a tooth on the front sprocket. I have the Spider Trac's and they are a great mud tire but are way stiff for just regular trail riding. Adding a pipe and rejetting with a one tooth drop will make a huge difference. I ride with the stock Ohtsu tires until a dice run then throw the Spider Trac's on.
Welcome to the Bomb club, you'll never ride another Atv. Are there any other kinds? Oh yeah, the ones you will pass!
