my 90s T5 with 44/305. It is surprisingly fast when surface is rough, rolling resistance of those Michelins is then comparatively good. A few weeks ago I passed two mamils; when they catched up two red lights later one of them really stared at the bike and asked where the motor is:-)
Have just worn out the rear rim so need to get another. Alu 28-spoke rims are hard to find.

took a look at the brommies further up in the thread, both of them are likely to have widened fork and triangle; mine are stock. the 44/305s i use are wide enough to be decent on gravel, they also work fine in snow.

btw, in snow bike geometry reveals itself. slack 'modern mtb' geometry and too much trail creates self-steering, and such a bike may hopelessly steer and skid back and forth, as the rider tries to keep the bike on a narrow track/ridge of packed snow for example after a car or people walking. its not uncommon that such a bike just comes to a stop.

the brompton is here pretty good, and even better with the smaller 305 wheels having shorter trail. it runs best if the handlebars are tilted somewhat forward, as to have the effect of a stem. this goes with the 349s as well.

have to say, one of the greater assets of the brompton in my view are the standard tires. they have decent puncture protection, and roll unreasonably well on tarmac. have used my other brommies together with friends with serious racers in 20+ mph peleton club rides, and the difference in rolling is small, not to say minimal. they go best just under 4 bar.

so i would not convert my only brommie to 305s, but having one extra for hikes in terrain or snow is perfect. an extra bike is also handy to have as a backup, or for loan to friends and family

well they are not ultra wide, they are 44, though i think on the fat side for a 44. in this size all kinds of sluggish children bike tyres are abundant; but can really recommend the michelins. they roll fast, and the rubber compound is adhesive to snow and ice, not stiff and slippery.

the ride is very good i think. it is at least fast enough to keep up with or pass any number of mamils on mtbs and racers. i am pushing 60 myself btw, so i am older than most mamils. but i dont wear lycra when commuting

on the brompton as with any small wheel bike its beneficial to position the handlebars forward a bit, this adds stabilty and compensates for the lack of gyroscopic force in the wheels. i like to have them just a bit more forward than when i took the photo. on my summer bromptons i have lower bars angled forward about 45 degrees.

it is then stable also at speed, but as with any brompton with the added benefit of really quick steering response.
