Varonha Frameworks winter bike / FW Evans 650b conversion rat bike fun

Tyres arrived - stated as 48mm but really only 41mm tall x 46mm wide on these rims.

Starting to get too many punctures with the above Gravelkings.

What are my other options for 650b x 48mm ish tyres with better puncture protection?

(Mainly for roads at the moment but would like them to be okay off-road as well)

The Dynamic choice would be Cavas.

Terravail tyres also exist in a durable version.

Cavas

I have been riding around on a pair of those for a few weeks and haven't had any punctures yet, plus they look cool.

Thanks all.

Are there any cheaper options? Cavas and Terravail are a little out of my league (for a beater, anyway).
Probably only looking to spend about £30-40 per tyre.

Cavas do look cool though : )

Same for me, only a few eight months.

I would also consider Schwalbe G-Ones.

Cheers @Tijs : )
The "raceguard" G Ones look pretty much perfect if I can find some in the right size.

Bit of a saga but now realise my mistake was to modify the frame around 1.9" Gravelkings with awful puncture protection.

A lot of other 650b tyre options come in 2" and are too big for this frame. If I could fit 2" tyres, the choice would be endless... but as it is there are very few options.

I've ordered some 47mm Vittoria Tereno Zeros. According to Rollingresistence they have much better punture protection than Gravelkings, and okay grip on and off road.

We shall see! I used to use Vittoria Rubinos until they broke my leg.

Anyway, If I could start all over, I'd have clearance for 2" tyres... and if I was designing it from from scratch I might even go with 26" wheels.

Hopefully this is of some use to anyone else considering a 650b conversion.

Schwalbe Marathons come in 27.5 x 1.65 and they are almost impossible to puncture in my experience

I like 26”, but you basically have only one choice there.

Continental contact urban?

Marathons are the dream! They were what I used for years on my old Galaxy. I actually bought some 27.5 x 2.0 Marathons but couldn't quite squeeze them in. I didn't try the 1.65's as I was worried about BB height... they might've been fine but I was keen to get something as close to 1.9" / 48mm as possible.

I've done no research, I just assumed mtb tyres were more common than 27.5s.
(I do like Contact Urbans though, I have them on my kid bike):

Took the Gaz bike out to France last week and went on a few very pleasant rides exploring the local lanes. We have a toddler now so touring holidays are still a while off, but it was great to dip the toes back in and be reminded that nothing is more civilised than a village bakery and a road without any hedges.

(Ended up replacing the Gravelkings with 47mm Vittoria Terreno Zeros... noticeably heavier but still very quick considering how tough they seem).
