Used the old Bubble wheelbalancer to balance the "new" Jeep Cj wheels. Works quite well, though it is old technology, but often that's best! These wheels are 15" and the tires 30/9.50, so they are wider and smaller and slightly wider than the oversize 750's . They have been cleaned, sandblasted and painted with care by a good friend, so I better not damage them soon! I noticed the Jeep rolls less and the gears are more suitable for this size. Much better! It comes close to the stock diameter.
