Jul, I forgot to mention the Panaracer options:  They offer a 26 x 1.75 Pasela PT, but also, in the Gravelking range, a 26 x 2.10.

I tried the Gravelkings on my Mercury in 2025 (650 x 48 mm, 46 actual).  They worked very nicely on tarmac and easy gravel.  BUT, I had to remove my rear tire when the expensive TPU tube valve said "Enuf!" after 500 kms.  At that point, I found that remounting the Gravelking on my tubeless-compatible rim was beyond what my arthritic thumbs could manage.  (Front tire, with my Thorn alloy rim, was no problem at all.)

That problem is mine, obviously -- but if that sort of thing is no problem for you, I'd recommend looking at the Gravelking option.  (My cycling buddy, Ron Séguin, who posts here, uses 26" Gravelkings on his Raven.  I think they're 2.00, but am not sure.)

Hope that's helpful -- good luck!

The measured weight of my 2.0 x 26 Dureme is 600g (agrees with Martin) but Schwalbe quote 750g…….   

What about Panaracer Gravelking SK ?
26x2’10 for 610gr each

Not looked at those, from UKTony's description they seem to be a bit more like Duremes than Supremes (more grip off road, more rolling resistance and a bit heavier than Supremes). The weights I noted for the 3 tyres I use most in the 559x50 size are :

Supreme 565g
Dureme  590g
Mondial folding bead 740g

And the Continental Contact Urban are 590g, probably because of the wire bead, I haven't found them with folding beads in 559x50, but they exist with folding beads, at least in the 16" size for Brompton folding bikes. 

The website https://www.bicyclerollingresistance.com is usually quite good at comparing different tyres, but sometimes I haven't agreed with their findings, notably when I try to extrapolate their results to another size of the "same" model of tyre.

There are a lot of good tyres in the "modern" sizes 29" (= 700C) and 27.5" (= 650B) , but choice is much more limited in the "old" 26" (= 559) size.

The irony of that is that I can now find very nice tyres for my ancient 650B utility bike.

I emailed the owner asking the size and he just said it was 'medium' and he was 5' 7" tall. Someone else with a different 485L for sale (with a rare Nuvinci hub) also said he was 5' 7" tall and it was good for him. I drilled down into Thorn's Sherpa brochure for January 2012 ie the Mk2 version. The 485L is listed on the site table as small. Pity as I might have taken it further.

Supremes are my choice for the best compromise weight/performance and durability for use mainly on tarmac. I don't yet need to replace the Supremes on any of the family bikes.

But I did check out the available alternatives in August 2025.

If they are still around when I need replacements, my current choice would be the Continental Contact Urban wire bead tyre. This is a bit heavier, much cheaper, and according to https://www.bicyclerollingresistance.com it is pretty much the same as Supreme as far as rolling resistance is concerned. And reasonably easy to find on German websites.

I have Continental Contact Urban in the 16" size on two of the family Bromptons, so far the tyres have performed very well and seem to be reasonably puncture resistant.

My favourites for mixed on/off road use are the Duremes. I still have a pair in use, but it is a long time since it was possible to buy any.

Last year, Marathon Mondial 50x559 were still available, both in folding and wire bead versions. I bought a pair of these for one of the  bikes I maintain for a nature reserve, where the bikes are used quite a lot on rough tracks. Mondial are a bit heavier than Dureme, probably tougher, but they don't roll so well as Dureme. But if they are still available if/when I need replacements for Dureme, Mondial would probably be my choice.
