I know you posted on my Mrs A Prius Tyres thread - for info the 2010 model has 17s as a standard fit with 215/45 R17 tyres, standard fit is Michelin Energy - which I understand are forgiving enough for Toyota to fit them to the new GT86 Coupe, which seems to be proof that total grip != handling.

I would be careful of fitting "bad" or "crap" tyres on the back, even in an FWD car - the rear does a lot more than just being dragged along, and if grip is the issue then understeer is easier to handle for most drivers - lift off, brake etc. A lot of tyre places here (UK) will only fit new tyres to the rear, and move rear ones to the front and most cars are FWD, very few RWD (BMW/Merc mostly) and very few trucks.

Just my 2p.
