the problem is as stated before, your best traction does need to be on the rear of the vehicle exactly as shown in that video. but you also need to rotate your tires.

just yesterday i had a customer come in with a $1200 set of LT tires where two had worn out after 12k miles.. i called up goodyear, the first thing they asked was for history of tire rotations. after verifying the tires had been rotated, air pressure was correct and the alignment had been periodically checked, goodyear gave him an $700 credit towards new tires. in my experience if you dont have documented rotations, you can kiss any sort of mileage warranties goodbye

also the video shows the lesser of two evils. think about it, the way the rear tires give out on the "wrong" car... do you really want those tires on the front of your car? you may not spin, but you still have greatly reduced steering control and stopping ability.

The tire guy selling you the tires and working on commision recomends buying 4 tires instead of 2? Gee I am sure that doubling his commision has nothing to do with that. That attachment is copied right off the Michelin web site. I am sure if there were a safety issue they would mention it. On all sites I checked it never stated you must replace 4 just recomended and then if you replace 2 put them on the rear. Seems tome since tires dont wear at the same speed you can always rotate them based on vehicle wear. After all if all tires had to be the exact same size you would not be able to rotate them at all.
