schwable tire rating

[Jay in Tel Aviv]

All this talk about tires has me looking at options for the Sam I use
for my 15 but soon to be 25 miles RT commute.

Schwalbe's website rates the Marathon Supreme as 5 for speed and 5 for
puncture protection. Kojaks get a 6 for speed and 4 for protections.
Ultrego DDs, a 23/25 mm road tire, get 4 for speed and 5 for
protection.

Does that mean that the Supremes are as fast as the DDs, and that the
Kojaks are even faster? Do DDs beat Kojaks and equal Supremes for
puncture resistance? Or is the scale different for road and city/
touring tires?

Cause if the numbers are as they seem I'm thinking about trying 25 mm
DDs on my commuter Sam.

I am using 32 mm Supremes at the moment, 60/80 psi front/back. 165-170
lbs of me + ~ 5-10 lbs of gear most days.

If you're thinking of the Ultremo, you might want the ZX, which comes in 700x28. I use those with light wheels for my go-fast road bike and they have been great. Good traction and no flats. I also have Marathon Supremes in 700x40. They are also a great rolling tire, and they have the cushion of being 40 wide. It's hard to compare directly with the Ultremo because of the size and weight difference. I haven't tried the Kojaks but I've heard good things about them.
