As said weight might be a consideration for folding but other than that there's not much benefit if its the same tyre. Foldable might/ might not fit easier its probably more down to the rim.I only ask because there are 2 options for Durano Plus tyres, I don't envisage needing to carry a spare tyre so thought I'd just buy the wired ones.
Must be a big pocket , how do you stop the chain from getting your clothes dirty ?Folding are much better.
Easier to get your bicycle in your pocket if you fancy walking for a bit.
