To achieve the same rolling diameter as the tyres originally fitted (175SR14) what size (would like a wider tyre) would I need to fit a 61/2x14 rim?

I'm not sure, but check out www.tirerack.com

They have specs on all tires they sell and lots of technical documents tha may answer your question.

Good Luck

Here's the tool you need to answer your question. It has changed since last time I used it so you will just have to play with it a little bit. http://www.powerdog.com/tiresize.cgi

the original tire size I used as a basis was the 195/70r14 which has a dia of 24.75 , the 175sr14 was very close to this , most tire guides list a rpm rating which can help you get close to the original revolutions , I have a 205/60 14 on mine which was 23.8 and the rpm rating was very close, alot of that info can be gotten at the brands website , good luck
