Updates = delete / insert inserts only create dead tuples if they fail. So, assuming no failed inserts, you're creating 55k dead tuples a day. You can run vacuum verbose to get a report on how many dead tuples your tables / database has to get an idea if you're vacuuming often enough. If vacuuming makes the machine too slow look at setting vacuum_cost_delay = 10 and see if that helps. Vacuums will take longer but won't be as intrusive.
