    OK, after doing some research its looking to me like I have to stay with the 8 inch. OK, so be it, now, do I want load range B or C? Will C give a more bouncy ride considering they are aired to 90 lbs?

    The VXR dry weight is 780lbs, can I get away with Bs? (590 x 2 = 1180 lbs)

    Been all over the page today, but finally made a decision and an order. I have decided that even if its too tight for the 12s, my fenders are only held on with a 1 1/2" wide piece of flat bar. It would be absolutely nothing to cut them off and re weld them back on higher. Not only will I slow my rpm down with the 12s, but I can also use a load range B that is rated for 780 lbs a piece, running 60 PSI. I hope I didnt bother anybody, I learned a lot today even with not really getting any responses.

    When you install a larger wheel+tire, the axle rises by 1/2 of the total increase in tire diameter. For every 1 inch that the new tire is taller than the old tire, the axle rises by 1/2”.

    Are you OK with having the trailer frame (and the ski) also rise by the same distance as the axle?

    On shallow angle launch ramps a higher trailer means the trailer has to go farther down the ramp before the bunks get into the water.

    You'll be fine. It'll ride better and easier on the bearings.
