Tyres

I've been pondering tyre choice for some time.  I want enough width to protect the rims and enough pressure to be fast.  Both the folder and the MTB (when running road tyres) run at 6-7bar on 1.5" tyres.  In the 700c size few tyres seem to go up that high unless you go much narrower. 

The Mavic wheels have a 15mm inside width which Sheldon Brown advises is OK for up to 32mm width but goes on to say that wider is probably OK too so perhaps 35 and 38mm will be OK too.  That is probably not a bad thing as it means the tyre will fit between the brakes on the front wheel - something I worried about in my earlier post.

I've liked the Schwalbe tyres I have elsewhere so I think the obvious choice with my likely usage mode is the Marathon Racer, which goes to 6.5bar in 35-622(700x35c).  The next size up is 40-622 but that only goes to 6bar and is rather strangely classified as being a narrower 700x38C - what's a chap to make of that.
