Folding Tyres vs Non-Folding Tyres

I can't agree with some of the comments. Tyres from all but the worst (are there any crap manufacturers?- I haven't come across any) brands are very accurately made and are no trouble to get on the rim. I find the wired tyres easier to fit - tube on rim (why are they always too long?!), fit the bottom inside the 'stands up on its own' wired tyre, wiggle the entire wheel inside both beads, bead on one at a time- usually without levers, even on my new excellent Marathon Plus 700C 35mms. Modern tyres are great!

I do get the ease of levering the bead back onto the rim but when new to fitting folding tyres they are horrible floppy things that turn inside out while you watch them and your hands get colder and colder at the roadside.

Like trying to tie the thread on a Christmas tree bauble but without the large glass of something agreeable nearby to take the edge off the fury.

Perhaps it's just me.

In the case of the Durano Plus, there's no material difference in the contruction and quality of materials used between the folding version and the wired bead version. It's purely a cost and weight differential. Wire bead being considerably cheaper than the aramid cord used for the folding tyres.

Unless you're wanting super cheap tyres, always get folding tyres and not the wire bead ones. 

Wire bead tyres are usually of a lower quality, weigh more and are more difficult to fit. £30 for a wire bead Durano Plus is taking the mickey, spending £3 more is definitely money well spent. 

Unless cost is a concern, always go for the folding version - lighter, better road feel, easier to get on and off (you'll want that while fixing a puncture at the side of the road in the cold and rain).

I have Continental GP400 folding. No tools needed for getting the tyre on and off the rim, which is probably a benefit because of the suppleness of not having a stiff bead.

Weight is the main difference if everything else is equal, but manufacturers often also use a lesser construction for the wire bead compared to the folding version - less threads on the casing, less supple rubber etc as a wire bead will never be "premium"

Yes, non-folding ones which are also called wire bead tyres are cheaper as compared to the folding ones. Also, the weight of non-folding tyres is higher due to which rider would have to spend more rotation to run a cycle.
