700x28-30-32 kerge ja vastupidav mnt kumm?

90 kg kaaluv isend vajab tsüklokale sügiseks, kui metsaalune tatiseks kisub, siledat kummi . Plaanib siis maanteele kolida. Hetkel tal all 35 mm RoRo võistluskumm, 310g

(metsas 5 bar, mnt-l 6,5 bar), mis kuumal maanteel kulub silmnähtavalt. Et kahvlivahe võimaldab kuni 35 mm, siis tekkis mõte soovitada kerget ja laia kummi - üks silmajäänud variant on shwalbe ultremo zx 700x28, 235g ja miski torkekindlama kihiga:

Mis firma/mudeli suunas veel vaadata?
23mm, 25mm kummid omanikku hetkel ei huvita, kuna ratta esi-/tagakahvel võimaldab laiemat/enamat ja omanikule meeldib alljärgnev laiema kummi põhjendus:
Road racing and open-road riding are very, very different and as a result,
demand different things from a bike.
TIRES - Open-road riding calls for efficient speed and with that, calls for
wider tires in the 700x32 range. The open-road cyclist often rides alone
at a more or less steady pace. As a result, they need fast, efficient tires
that allow them to carry speed, even if the road is less than perfect. In
contrast, road races like the Tour de France are won by acceleration, not
speed.
