Wow! Thanks to all for your help. To newer drivers like me and my son, the wealth of knowledge you all share is invaluable. We now have many ideas to help us next time out. This type of assistance will help keep this sport alive in the future. Trying to constantly improve is half the fun. By the way, the front tires are 26x7.50-15LT. Any suggestions? The are also Mickey Thompson's and say maximum pressure is 40psi with a suggested 30 psi. What do some of you run?
