If you’re actually looking for 40mm x 700c then I’m running 40mm Vittoria Terreno Dry on my Kinesis, they measure 40mm exactly on a 19.5mm internal rim.
Great tyres, fast, floaty, seem sturdy (I run latex tubes, no punctures so far @ 40psi and 85kg). Generally great fun on all surfaces although obviously you can’t expect great straight line braking on wet grass or mud, given that they’re virtually slick.
Easy to set up tubeless as well, I got them seated and inflated using a standard track pump on Pacenti rims with 2 wraps of Pacenti rim tape and Pacenti valves. I just didn’t want to commit to putting sealant in etc. as I’m a serial tyre swapper, so went back to tubes. Reassuring to know how easy it would be to go tubeless if I wanted though.
