Completely disagree with where to put new tyres. New tyres go on the front. This is my personal prefernce. Sure if you have worn tyres on the back the car is more likely to oversteer, but there's a shit load more you can do about oversteer than understeer. It's been proven on track that race car drivers can push the cars much faster on track with the newer tyres on the front. Now in all fairness they were more likely to spin out with the new tyres on the front but they were pushing things. They are also professional race car drivers, which is a fair note. Yes putting the tyres on the back makes the car more "stable" and understeer oriented, but as a car enthusiast I'd rather less stable with higher limits. I think for the average Joe that knows nothing about handling you are absolutely correct, but for me, the front is the way to go.
