To those of you who responded to my stem raiser question, thank you. I installed the Delta that was recommended and it is exactly what I was looking for.
Tire question...If I go from 700x35s to 700x37s, I know that the tire will be wider but is it also taller? Will the wider tire have a larger sidewall giving the tire a higher silhouette? My fender can accommodate 2 to 3 mm of additional width, but not much more than 2 or 3 mm of additional height to have adequate clearance. If it makes a difference, I'm looking at Continental Top Contact II's. I've had good luck with Continental and feel confident with them. I also know that Continentals tend to run narrow.
Typically yes wider tires are also taller, but... You really can't go by the listed width since they are often not accurate, sometimes they are off by a fairly significant amount. You can probably compare the same model in different sizes, but different brands and models not so much.. I don't know about the top contact 2 but some continental models are narrower than their listed width by a couple mm and maybe a good bit more. Also width/height relationships could possibly vary with model. Some models could possibly have a higher or lower aspect ratio, not sure how much of an issue that might be though.
MAK, Continental tires (all of my bikes are on them) measure their size from bead to crown and are generally close to what is labeled when mounted and aired up. Width is often, if not always less than height. The 37 mm TT2K tires on my back-up touring bike are noticeably narrower than the 35 mm Panaracers that I had on my primary touring bike. Both my touring bikes have the same frame, BTW. They're maximum recommended tire size is 35 mm.
