Can only seem to find WTB Nanos - anything else?
Landcruisers
Landcruisers + 1
Schwalbe Smart Sam
Landcruisers very heavy though. Would prefer folding, don't need puncture protection etc.... Tread wise thought both those look great.
Ah - now you're modifying your requirements....
Refining, scotroutes.. refining.
Seems to be loads of stuff available but ONLY in heavy wire beaded puncture proof versions..
45c or more preferred.
WTB Nano
Doh!...
Solid centreline is usually marketed at the leisure / casual user as it re-assures them that there's less rolling resistance. I reckon that's why the tyres tend to be heavy/cheap.
I think I'll give up on 700c, looks like 29x2.1 or 2.0 is going to be best. Way more choice in what I want.
The reason I want solid centre line is because I think it'll wear less on road.. but there are quite a few nearly solids like Crossmarks. Sounds like Nanos don't wear that well anyway.
Hmm...

Clement Xplor USH.
Halo twin rail
I've got those vee rails 1.75 set up on the crosser, pretty good. Tiny bit of overlap at 45c, more of a buzz. The nano have a better centre line though.
I have a pair of the Challenge Gravel Grinders and they are 38c good enough off the road and great on the road - well worth a try.
What application is it for?
Gravel bike? MTB that you ride on road as well?
Do you have any other requirements than not heavy, long lasting and >45c?
Rigid 29er that currently does mixed road/off road without rocks or roots. I'm taking it to the US this summer where it might be called upon to do road duties with some friends who ride road.
I've only got two sets of tyres: Spesh butcher/purgatory for normal MTB and some Bontrager Team Issue race things that have a sort of centre line but are 2.35s. I'm now wondering if I should just get some actual road tyres if I do need to go on a road ride, then change to the Bonties for the mixed stuff. I don't like them that much so if I wear them out then good 🙂
Or, just not worry about it and have the roadies wait for me. Or just train more and be so awesome that they can't keep up with me anyway.
I'd go with something like a race king 2.2. Inflate to 50psi for the road and let air out again for your mixed ride. The black chilli compound seems to tolerate road abuse quite well. Got >1k miles on my Xkings, and they will probably die due to cuts before the tread wears out.

Boom, I ride these:

Folding, black or skin wall, 510g. Finest quality, made by Panaracer in japan.
I bought them in the states, but veto vitality here can get them:

They are also spectacular puncture magnets - on paper they look great, but had 2 work colleagues try to commute on them, and punctures were a daily occurrence for both.
Mike Hall seems to have the vee rail on his Pivot. Wonder if he's doing the divide on them.
+1 for file tread CX/gravel tyre rather than solid centre line which tends to be the preserve of cheap commuter tyres. Currently got Challenge Alamanzos on my CX bike as they were silly cheap at P-X, doing lots of mixed on/off road rides and they are spot on.
Negligible rolling resistance on tarmac, useful off road when dry.
The answer is Maxxis Raze :

Raze: not the most robust tyre. My record is three punctures in less than ten miles 🙂 Nice otherwise. I've been putting up with their failing.
@franki
Yes, yuo are quite right. I dint spot that. Just searched for an image, but its pretty close.
@fifeandy
Not had a puncture in 2 years of gravel leisure ride/commuting on tarmac/light offroad. i do run them tubeless tho', so maybe thats why. Good job i haven't actually, as they're total buggers to get on-off rims.

Ooo they look interesting. Don't suppose you've ridden nanos to compare on / off road?
I'm generally happy with the nanos but they do seem to wear fast on the tarmac bits
I've come to quite like the Schwalbe Smart Sam's on my Peregrine (47-622 or '28' x 1.75's). They seem to roll quite nicely on tarmac with a bit of pressure in them.
They've not proved to be [i]especially[/i] robust riding through the stuff left after hedge flailing tho' - but that's a pretty tough test for anything ...
Maxxis Rambler looks pretty good. Nice and light/tubeless (tubeless is essential I think for this sort of thing)

This guy has tested both in many conditions:

http://ridinggravel.com/gravel-news/wtb-nano-40-tcs-tires-at-the-finish/
They are more road biased than the Nano. Probably a great choice if you are looking to be faster on the road with better wear than Nano, and are willing to compromise some off road ability for it. Quite a few people set them up tubeless.
I would warn away from heavy stiff tyres like land cruisers if you want to enjoy riding your bike. Go for high volume, supple casings and lightweight.
The high TPI version of the Clement MSO might be a shout too, but thats 40c.
