Our place insists on us tapping wheel nuts in a morning and at night and then torque em up once a week or if they’ve been off do em after 100 clicks. Steering wheel doesn’t get done as regular coz there ain’t as much chance of it killing someone if it falls off 
once a week, always one or two loose 
. if wheels been of it’s 100km and the following two days
our place like you to check the nuts once a fortnight, personally i do the ones on my motor once a week as it goes off road a fair bit doing these generators
