OK little problem, rears are running extremely thin and need to get a new pair without spending a fortune...

At the mo the cheapest I can find is Goodyear F1's £130 each and SO-2's £135 each...

I don't want to put crap tyres on the rear being wheel drive but need to find a cheap good alternative, anyone know of any or know a cheap place to buy tyres ???

Need 225/45/16's btw
