I bought continental contact 700 x 32 tires because I wanted a wider tire than the 28mm tires I currently have on my bike. To my disappointment when I mounted the contacts and pumped them up they measured slightly narrower than 28mm. With my bike and fenders, 32mm is about as wide as I can go. It looks like the next size up in the contact is 37mm. Does anyone have these and what is their true width? Thanks.
