Hi I'm replacing all 4 tyres on a Ford Fiesta 1.3 Flight and have decided to use National Tyres. I put the same tyre size I have now into their website (175/65 14) and it quoted £160.00 fully fitted price for the Avon CR322 which is the one I've decided to go for (has a speed rating of T). However when I don't specify an exact tyre size and just put in my registration number it comes up with the same tyre but instead size 155/70 13 T. This size isn't specified in the owner's guide whereas the other, more expensive first one is. This 155/70 13 T option is also £20 cheaper in total too.
Therefore what I'd like to know is whether the 155/70 13 T is appropriate or I should just stick to the owners manual and go for the more expensive 175/65 14 option. And why does the website give you an estimated tyre size which isn't specified by Ford? I decided on the CR322 due to its high performance and chose National because of their BOGOF offer.
Any help would be greatly appreciated.

You mean you can't put a 13" tyre on a 14" rim? I would never have thought of that
