One other thing that you can try. Run the Hoosiers without the tubes. The tubes weigh 8 lbs a piece or so. I ran that 26x8.5 Hoosier without tubes for a couple of years with no issues. You may have to check your air pressures more often. I found that I lost a few psi when they sat for a week, which is no big deal, I always adjusted air pressure before each pass anyway.I agree. The Hoosiers are 6lbs less per tire and less contact to the ground.
