i dont care. i'm not a gram counter, if i wanted to lose weight, i've got about 80 pounds i could stand to lose out of the engine of said bike. i just dont want to spend the money and find out that they dont fit my bike.

i'd like to get a studded winter tire but the reviews for the Nokian a10 don't read too promising with so few studs. and the Schwalbe marathon winter seems the best bet but only come in as narrow as 32mm.

I think the error is that you guys are using the "c" value which measures rim width rather than ETRTO which measures tyre width.

The type of miscalculation is in the same category as stating the more narrow tyres roll better than wider tires.

See pages 7 and 22 for the width-measuring error and the wide v. narrow difference.
