Any advice would be appreciated has there been any probs with changing the spec from 215/50/17 to 225/45/17 they just seem to be cheaper ?

Many threads on this - have a search and you'll find loads. Basically no problem in changing and you'll get more choice of tyres and a little less expensive.

does it handle a bit better ?

You'll feel a slight difference yes due to the stiffer sidewall - nothing major though.

Dosent it affect insurance if you have diffrent tyres on ?

Shouldn't do as its a listed size in the owners manual

But you are changing it from when it left the factory, might be worth checking, insurance companys just need the smallest of excuses not to pay out !

Changing to the alternate size will make your speedo over-read. ie, at an indicated 70 mph you'll probably be doing something like 65 mph.

Also as the tyres are slightly smaller in circumference your mileage will increase slightly more than compared to someone who still has 215/50/17's fitted.
