What is the reasons to uneven tire wear in a four wheel drive vehicles?

I am not a mechanic but through having driven a four wheel car for the past 7 years, my experience is such that there are generally 3 reasons for uneven tyre wear: 1) Unadjusted Toe of tyres
2) Unadjusted camber of tyres
3) Bad driving habits (Making Tight corners at speed, breaking hard)


Solution: Check wheel alignment regularly

1. Check tyre pressure as recommended by car manufacturer
2. Negotiate tight corners gently
3. Avoid breaking hard as much as is possible.
