4x4 tire chains Nissan Patrol

4x4 tire chains Nissan Patrol. Testing to see what's better? 2 wheel drive vs 4 wheel drive, 4 wheel drive vs 2 wheel drive with chains? Or: how much better is 4 wheel drive with tire chains all around that just four wheel drive?? Today is the day to test & prove what I suspected. Tire chains on 2wd seems to be more effective than 4x4 (with these poor tires anyhow) How much better would it have been if my old diesel wasn't blowing so much black smoke?? Thanks for watching. And for those who ACTUALLY read the description - congratulations!! You are likely not only your mother's favorite child - but possibly my favorite viewer!
