2003 Ford Focus Tyre wear

I live in a country with fairly bas roads for a start, some of the mechanic professionals are a bit iffy to say the least and I am on the point of putting 4 new tyres on my car. Bit concerned about the wear on the front ones, I had previously a mondeo and the wishbones were changed about this sort of milage as they had caused abnormal wear on the tyre as they themselves were worn. Is there a simple way to check the focus ones before I spring to the expense of new tyres. Thanks
