I know this subject has been brought up before but it always seems that people veer off subject. Without sending me a link to another thread (i have read those) can someone answer this for me

I know there is no REAL answer to this just opinions... but id like to hear those.
I go off-roading maybe once every month and the rest of the time is commuting. That being said id like to get a tire that wont hurt my highway and city miles (better would be nice) and not blow while going over Mild to Moderate rocks. I don't do anything crazy "yet".
How long have your stock tires lasted? Mine are at 29k and the tread is almost shot.
