New tyre question

[slythgoe]

... okay so it's probably not new, but I couldn't find the answer to my tyre size question in the search...

Can a standard Tuscan can run on:

Front:235/40/18 and Rear:245/40/18
Front:235/40/18 and Rear:255/35/18
Front:235/40/18 and Rear:255/45/18
Front:255/35/18 and Rear:255/35/18

and ... if so...

what's best???

I want something that looks good and handles well... he he he... there's a new concept.
