Which tyre would you have and why?

Also if you've got a preference tell me what it is and why you like them over the above two

I'm looking at 215/35/18 or 225/35/18, had some good prices and have found a cheap site online which is cool, but i'm undecided on which one to go for?

Avon ZZ3's are another one i've enquired about and seem a good price...?

Cheers
