thinking about faster rolling tire for Brompton in budget

Anyone try Primo Comet on your Brompton before? Are they really durable in term of puncture resistant?
The current Schwalbe Marathon HS are pretty tough but they are heavy and slow...
Have been heard that Kojak has quality issue lately. Not very durable anymore?
Schwable One tanwall is very nice BUT $80 per bicycle tire! I think that is how much I pay for my car tire just saying

I have been running them for years. They are very supple tire. They are fast and efficient. Rated at 85 psi. I run 80 psi rear and 70 psi front. Most of the time the pressure is under that amount. They become more susceptible to flats as they wear down. I end up replacing them before they wear completely due to more frequent flats. I ride in the city so I am more exposed to glass and metal shards. A few years back I could get buy them cheaper than I can now.

The Schwalbe Marathon HS420 'Green-Guard' actually rolls pretty well for a touring tire - better than the Kojak.

The Kojak is lightweight and look nice but performances wise its low level: doesn't roll fast, wear fast, limited puncture protection.

Indeed, the Marathon Green Guard has a good rolling for a touring tire but its heavy.

I think the best compromise is currently the Continental Contact Urban: as strong as the Marathon, good rolling, weight much less.

Been using Primo Comets for years; they're decent.
Rolls fast like Kojaks; about the same puncture protection level:

Faster rolling in ISO40x349mm: try Greengear Scorchers (120tpi) or TruBlu (120tpi). No personal experience with these tires; they're fat for 16s; recumbent cats and kittens say they're fast; less expensive than Schwalbe Ones.

I have a set of them on my folding recumbent, replacing a set of marathons. They're much faster than the marathons but I can't give a comparison to Kojaks. I've been happy enough with the durability but I only have ~800 miles on them and no cuts/punctures but this is mostly loops around Central Park, which is pretty light on puncturing debris.

You might also consider the new Conti Urbano tires. I had tried to put 406 Schwalbe Pro-Ones on my Birdy but could not get them to seat on the rim after hours of trying. Replaced them with the Urbanos, which have a notably stiffer casing than the Pro ones but don't feel especially different when on the bike. Again, not a lot of insight on the durability: 400 miles without issue.

Scorcher are indeed very fast but they are 40x349 and too wide for the Brompton.

Without mudguards or with modified mudguards it seems possible: https://jnyyz.wordpress.com/2018/06/...-the-brompton/.

Note that the link above is for the Scorcher kevlar, not the faster Scorcher 120. I do not know if the actual width+height of the Scorcher kevlar and Scorcher 120 are the same.

It will also depend of the rims width (wider rims reduce the tire height which is a problem for the rear wheel).

Now about the performances, I had Scorcher 120 on my Birdy with ETRTO 349 wheels.

They are indeed super fast and I had no issue of wear or puncture on roads.

But they are pure road tires, do not use them on trails or unpaved roads.

I tried the Comets for about a week but gave up after a couple of flats. One was a pinch flat after I didn't see a pothole so I suppose that doesn't really count. But the second happened just a few days later and was due to a very typical shard of glass that one might expect to encounter on any northeastern city street. I decided they weren't up to daily commuting use and put the tires on my partner's bike instead. They've since been fine through a few beach trips and trail rides.

The Scorcher 120 also do not like shard of glass.

And, BTW, aren't cheap tires !
