Continental is notorious for exaggerated sizing. No surprise. My 700x32 Twister is also considerably smaller than the stated size - and at 450g for the wire-bead model seems excessively heavy - but other than that it is a GREAT tire, with low rolling resistance on the road and great grip in all conditions from pavement to gravel to even gooey mud.

"this thing is gonna pedal like peanut butter" I am shocked it rolls as well as it does Thing is I was looking for a 37-42 for off road singletrack tire. Oh well. Ever measured a Michi Jet they clain 30 but the thing is nearly 36 on open pros at 72lbs? Ya think these guys could get it staight.

the hutchinson acrobats i have are labeled 37 but are really 30's...and they weigh a ton.
