This question is possibly a better fit in the commuting forum, but we all ride bikes for transportation, so I'll ask here:
Earlier today, I replaced my 2009 Continental Contact 622-37 tires with new Continental Contact tires. (It amazes me that I replace rims every 18 months, and tires every 5 years...) I like moderately fat road tires, because they're comfortable in general, and do particularly well on Seattle's vast expanse of crumbling pavement. The new tires are also 622-37 tires, it says so right on the sidewall, yet they are noticeably skinnier than the old ones. What gives? I mean, they're still good-quality tires, but dammit, I thought I was buying 37s, not friggin' 32s or 34's, fer cryin' out loud... Has anyone else noticed this with other brands of tires, or is Continental the only one trying to cut back on materials costs?
