Changed stock tires and mounted titan 489's on 00 wolverine rear tires will not seal, leaking at bead tried bead sealer at local auto parts store helped but not totally still leaks off after an hour or so. Just as info went to 25x10x12 and 25x8x12 thanks in advance.

 

Make sure the tires seated into the wheel beads.
This can sometimes be tricky when doing it yourself.

If you cant get them to work I would buy tubes.
