I have been mounting own my tires for over 20 years. I have always had 700x6 on the mains of three different strait tail 182's. I just bought a set of 800x6. I think I have been using Air Tracks. Well this time I went a bit more expensive and bought Good Year.
Always in the past the tires went on the rims with ease. This time the tires are really tight. I did manage to get one mounted but had to use soap and use a piece of all thread rod and spanners to pull the wheel haves together. Tightened the bolts and aired it up and it looked as if the tire went on the rim all the way. After letting out the air the tire pulled away from the edge of the rim about 3/8 of an inch. What am I doing wrong or is this standard for some tires.
