Anyone have any idea what the weight difference is between a 25 vs. 23 in Vittoria Open Corsa CX?

I ride 25's, a pal rides 23's, he asked me what the weight difference was, to which I had no idea. Recent vintage models in 23 vs. 25 aren't on the listings here either.

(Short of taking tires off and weighing them on a gram scale, I thought I'd ask here first.)

Obviously it's splitting hairs, but the number is the number and that's all I'm looking for.

If ya got it, many thanks!

I believe that Vittoria lists them at 210g and 220g, at least according to one chart I remember seeing.

thanks!

duh....i should've gone straight to vittoria site. it's listed right there.

you are correct: 23's are 210, 25's are 220.

(assuming that manufacturer weights are correct.)

My 25s weighed in at 221 so were at least fairly accurate. See what the WW listings say for others perhaps

21: 221g and 212g, both with some mileage on.

Vittoria.com lists as 210gm and 220gm. IME I have found Vittoria claimed weights to be quite consistent with real weights. I just installed a set of 25c 320TPI and they weighed in at exactly 220gm. With only a 10gm difference between the 23c and 25c it is sort of a no brainer to choose the 25c tire...less rolling resistance, more comfortable and slightly more durable. EM3

That, sir, is the nail on the head. I doubt if his bike will fit 'em. It's already ridiculously tight w/Zipp 303's and AX Orion brakes, to the point the brake quick release has to be left wide open. There's no way 25's would squeeze in there.
